Version 2.0.01
BMC Performance Manager Express for EMC Disk Arrays is an
agent-less Performance Manager for the BMC Portal environment. It
allows you to automatically discover and monitor every aspect of
EMC disk arrays, from the general health of the array to the
performance of the LUNs and from the file systems space usage to
the mirroring and snapshots mechanisms latency; and to consolidate
diverse monitoring needs within the Portal framework through a
single solution.
To setup a complete monitoring of the disk array, we strongly
recommend you to also use BMC Performance Manager Express for
Hardware that covers all the physical aspect of the disk array
(status of the disks, ports, temperature, power supplies, power
consumption, etc).
Being a Performance Manager specifically designed for BMC Portal,
BMC Performance Manager Express for EMC Disk Arrays uses the
Portal’s web-based interface and features for installing, managing
and monitoring your infrastructure.
Getting Started
Version 2.0.01
This chapter describes the prerequisites and the procedures you
must perform before installing BMC Performance Manager Express for
EMC Disk Arrays. Please follow the given instructions carefully in
order to ensure a successful integration of the solution within the
Portal environment.
Minimum Requirements
The computer on which you install BMC Performance Manager Express
for EMC Disk Arrays should already have:
1. BMC Performance Manager Portal version 2.5.00
2. Access to an RSM i.e. Remote Service Monitor
The RSM program must be installed on a Windows platform. This can
either be same as the server where the Portal is installed or, any
other Windows computer on the network.
Once you install BMC Performance Manager Express for EMC Disk
Arrays, you can add as many elements as you require in your
monitoring environment.
Enabling the statistics
On EMC Clariion and VNX storage systems, the statistics need to be
enabled to allow BMC Performance Manager Express for EMC Disk
Arrays to collect statistics and to monitor performance.
Using Navisphere
· Open Navisphere
· Click Properties.
· Be sure SP A and SP B are in the Storage Processors section
· Click the box for Statistics Logging under the Configuration
section
2. For locally attached CLARiiONs, check if authorization info is
present
3. Run the dv command from EMC TestSMIProvider. Make sure all
arrays are discovered without any errors
4. Make sure performance is turned on in the Profile for storage
arrays
5. Make sure there are instances for the
CIM_BlockStorageStatisticalData class:
· Run Tek-Tools testProvider or EMC’s testSMIProvider
· Type ein for command
· If no instances are returned, reset EMC Provider
6. Once complete, resume steps 1-3.
If you are using a version older than SMIKit 6.4.2, the EMC SMI-S
Provider does not recognize changes in the array when a LUN or RAID
Group is created or deleted from Navisphere. It is thus recommended
to upgrade your EMC SMI-S Provider to version 6.4.2 or higher to
benefit from the auto-synchronization mechanism set by default to
one hour after the last update. If you do not upgrade your EMC
SMI-S Provider, you will have to run the refsys command from
testsmiprovider each time you create or delete LUN or RAID groups
from Navisphere.

Version 2.0.01
Overview
To integrate a Performance Manager into BMC ProactiveNet, you need
to first install and configure the solution in BMC Portal,
automatically enable the application classes and create a specific
adapter. An adapter for BMC Portal facilitates pulling of
performance data from existing BMC Portal solutions into BMC
ProactiveNet. Using an Adapter, you can import BMC Portal
application classes (provided in a Performance Manager – PM) into
BMC ProactiveNet. The Adapter periodically synchronizes the
performance data collected by these application classes into BMC
ProactiveNet.

of a single PM independently.
Once created and imported, the Adapter will be displayed in the
Devices folder of the BMC ProactiveNet Operations Console.
Managing Baselines and Key Performance Indicators In order to
facilitate the detection of abnormalities on your monitored
environment, BMC ProactiveNet calculates baselines per parameter
(metrics or attributes) based on values collected over a specified
period of time to determine a normal operating range. When the
collected values for these parameters are out of range, an alert is
triggered.
Some parameters are identified by default as Key Performance
Indicators and therefore automatically included in the base lining
calculation.
42Managing Baselines and Key Performance Indicators
BMC Performance Manager Express for EMC Disk Arrays
Version 2.0.01
Managing baselines
The baseline is the expected normal operating range for a metric or
attribute of a monitor.
The baseline is calculated by collecting the values for a monitor’s
attributes and metrics over a specified time period and
establishing a low baseline value (consisting of the 10th
percentile of all the values for a given time period) and a high
baseline value (consisting of the 90th percentile of all the values
for a given time period), taking a weighted average of these values
over time. A higher weight is given to the latest data being
factored into the baseline average. The accuracy of the baseline
improves over time.
Requirements for baseline generation
For baselines to be generated for an attribute, that abnormality
threshold means that the threshold exists and is not suppressed.
Additionally, if the Key Performance Indicator (KPI) mode is
active, only those attributes that have an active abnormality
threshold and are also KPI attributes will have baselines generated
for them.
Absolute thresholds (with "outside baseline") or signature
thresholds do not satisfy these requirements.
Managing Key Performance Indicators
The KPI attribute of a parameter can be activated or deactivated
manually through the BMC ProactiveNet Administration Console. In
this PM, some parameters or attributes have been designated as
important indicators of performance (KPIs). We do not recommend
that these default settings are modified.
However, advanced users may activate or deactivate KPIs from the
BMC ProactiveNet Administration Console.
To add or remove Key Performance Indicator (KPI) attributes for a
monitor type
1. In the Administration Console, from the menu bar, choose Tools
> KPI Administration. The KPI Administration dialog box is
displayed.
2. From the Monitor Type list, choose the monitor type for which
you want to add or remove KPI attributes. A list of attributes for
the selected monitor type is displayed.
3. In the KPI column for the attributes that you want to add or
remove as Key Performance Indicators:
· select the KPI check box to add the corresponding attribute as a
KPI
· deselect the KPI check box to remove the corresponding attribute
from the KPIs for that monitor type
For complete and detailed information on this procedure, please
refer to the BMC ProactiveNet documentation available from BMC Web
site.

User Guide
Version 2.0.01
BMC Performance Manager Express for EMC Disk Arrays monitors all of
the performance metrics and usage statistics of your EMC disk
arrays, such as file disk space usage, storage controller
utilization, I/Os on the disks/controllers/volumes, etc. It
continuously monitors the activity of each array and is also able
to build reports on past utilization statistics.
To setup a complete monitoring of the array, we strongly recommend
you to also use BMC Performance Manager Express for Hardware that
covers all the physical aspect of the EMC disk arrays (status of
the disks, ports, temperature, power supplies, power consumption,
etc).
This chapter explains how to use each monitoring tool i.e. a
separate application class within the BMC Performance Manager
Express for EMC Disk Arrays by Sentry Software solution.
BMC Performance Manager Express for EMC Disk Arrays is a
Performance Manager specifically designed for BMC Portal;
consequently, it uses the same common features and procedures of
BMC® Portal. This document assumes that the user knows how to use
the Portal and therefore explains procedures only related to BMC
Performance Manager Express for EMC Disk Arrays, and not on how to
add Elements, Element Profiles etc. Please refer to the BMC Portal
documentation for details on how to use the Portal.
Checking Available Spare Disks
To avoid any loss of critical data, it is essential for a disk
array to always maintain a pool of spare disks that can replace the
faulty disk when a disk failure occurs. A disk array without any
left spare disk will not be able to keep the level of data safety
and performance in case of a disk failure.
The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports
the number of spare disks available for each disk array monitored
with the solution. By default, a warning is triggered when no spare
disk is available (Spare Disk Count is set to zero).
Verifying the Number of Available Spare Disks in Your EMC Disk
Arrays
49Checking Available Spare Disks
Version 2.0.01
1. Select an element group in the tree view (the main
Infrastructure group, for example)
2. Click the Reports tab. Create a report for the last 24 hours,
bottom 50 values of the Array| Spare Disk Count parameter of the
EMC Disk Arrays application class for the BMC Performance Manager
Express for EMC Disk Arrays by Sentry Software solution.
Report – Available Spare Disks
Detecting Oversubscription Situations (Thin Provisioning) We call
an oversubscription situation when:
1. The storage pool is configured for thin provisioning (“thin
storage pool”)
2. The storage pool is oversubscribed, i.e. the total disk space
visible to the hosts (subscribers) is greater than its actual
capacity (this situation is normal for a thin pool since it is its
very purpose)
3. The storage pool actual consumed capacity is nearing 100%
Such situation is highly critical because the inability to allocate
additional space to a LUN when requested by the subscriber host
will lead to catastrophic data loss and corruption.
When the conditions described above are met, the solution sets the
Oversubscription Situation parameter to 1, automatically raising a
warning. By default, the warning for Oversubscription Situation is
issued when the Consumed Capacity Percentage parameter goes above
100%. This threshold can be configured in the input properties of
the solution.
50Detecting Oversubscription Situations (Thin Provisioning)
BMC Performance Manager Express for EMC Disk Arrays
Version 2.0.01
Configuring Oversubscription Threshold
1. Click the EMC Disk Arrays icon and then the Configure tab.
2. Edit the Oversubscription Situation Threshold (%) property to
the appropriate value. When the Oversubscription Situation
parameter triggers a warning, it is highly recommended that the SAN
administrators add capacity to the storage pool as soon as
possible.
Diagnosing Slow LUNs
If a system administrator complains that his servers are
experiencing slow I/Os performance and that it is caused by the
SAN, you may want to verify the actual response time of the LUNs
the server is relying on.
The Response Time parameter of the SEN_EMC_VOLUME class represents
the average time it took to complete the read and write operations
on the LUN during the collection interval. Typically, the average
response time is below 10 milliseconds. You may also want to
compare this value to the response time of the other LUNs to see
whether one server is really getting worse I/O performance than
another.
Volume - Response Time Parameter
If the response time is low, you will need to check the amount of
data that is written and read on this LUN. The bad performance may
simply be due to an abnormally large amount of data to process.
Otherwise, the problem is maybe between the disk array and the
server, in the fiber links.
51Enabling the Debug Mode
Version 2.0.01
Enabling the Debug Mode
By default, BMC Performance Manager Express for EMC Disk Arrays
sends only the most critical information, warning and error
messages to the Application Collection Status parameter. Most
often, this information is accurate enough to ensure that BMC
Performance Manager Express for EMC Disk Arrays is functioning
properly. If you encounter an issue and wish to report it to
customer support, you will be asked to enable the Debug Mode and
provide the debug output to the support team.
1. In the Configure tab >, under Tasks, click Elements
2. Select the Element whose debug output you require and click
Edit.
3. Scroll down to Application Classes > click the Application
class for which you want to enable the debug mode > click
Edit.
4. Select Yes from the drop-down Debug Mode list > Save By
default, BMC Performance Manager Express for EMC Disk Arrays sends
its debug output to: %
RSM_HOME%/RSM(xx)/server/rsm/log/sen*_debug.log".
5. Wait for 15 minutes and then disable the debug mode by selecting
No.
6. Send the debug file to the support team.
Pay attention to the file size -the debug output of BMC Performance
Manager Express for EMC Disk Arrays could be very large if enabled
for several days.
Identifying the Hosts that can Access a LUN In most SAN
configurations, each LUN belongs to a storage group whose host
members are the only ones authorized to access the LUN. This is
called LUN masking. For each LUN, the solution displays its WWN,
the storage group to which it belongs to as well as the hosts
member of this group. In most cases, identifying the storage group
of a LUN is sufficient to recognize the server that is using
it.
52Identifying LUNs not Owned by their Normal (Default) Storage
Processor
BMC Performance Manager Express for EMC Disk Arrays
Version 2.0.01
Identifying LUNs not Owned by their Normal (Default) Storage
Processor The Owning Storage Processor parameter reports the name
of the controller that handles I/Os for each LUN. If a LUN is not
currently handled by its normal (default) storage processors, the
name of the default controller will be indicated as SP_B (default:
SP_A)”.
To identify LUNs that are not owned by their normal storage
processor, you simply need to list the Volume objects where the
Owning Storage Processor parameter contains the string
Default.
Identifying Most Busy LUNs
To identify the LUNs that generate the most traffic on the disk
array, use the Read Byte Rate and Write Byte Rate parameters of the
LUN class that expose the data throughput for each LUN. Use these
parameters to report on the total data traffic (per hour or per
day) on each LUN in GB.
To make sure that traffic is displayed cumulatively per hour,
select a time window of at least 12 hours in the graph window,
select at least 7 days to visualize per day cumulative data.
1. In the Status tab, click the Volume for which you need to check
the LUNs activity, then expand the LUNs object to display the
Read/Write Byte Rate parameters.
53Identifying Most Busy LUNs

2. Click the History icon to automatically display a graph that
shows the Read/Write Byte Rate values collected for a selected
parameter during the previous six hours. You can customize the
chart and table to show parameter history for different time
periods.

Version 2.0.01
View ing a LUNs Read/W rite Byte Rate as a graph
Identifying a Storage Processor (Controllers) Overload To visualize
the activity of a controller in an EMC disk array, use the
Processor Utilization parameter of the SEN_EMC_CONTROLLER class. A
warning is issued when the processor utilization goes too high,
which means that the controllers cannot keep up with the load on
the disk array. It is then important to identify what is
overloading the controllers.
The Response Time parameter of the SEN_EMC_CONTROLLER class
represents the average time it took the controller to process the
read and write requests of the hosts. The higher the Response Time
goes, the slower I/Os the servers will get. By default, the
solution triggers a warning when the controller takes more than 10
milliseconds on average to complete the I/O requests and an alarm
when the response time reaches 100 milliseconds.
Monitoring the Efficiency of the Caching Mechanism Each controller
in an EMC disk array can be configured to use a specified amount of
memory to cache the read and/or write operations. The solution
reports the amount of memory configured by each controller for the
read and write operations.
The Write Flush Byte Rate represents the rate in MB/sec at which
data is committed to the disk (i.e. physically written). This value
is to be compared with the Write Byte Rate of the disk array.
55Monitoring the Efficiency of the Caching Mechanism
BMC Performance Manager Express for EMC Disk Arrays
Version 2.0.01
Comparing W rite Flush Byte Rate w ith W rite Byte Rate
The Cache Dirty Pages Percentage parameter represents the amount in
percentage of the write cache that has been modified by host write
operations and not yet flushed to the disks. Reaching 100% means
that write case is too small and cannot handle the flow of write
operations.
Checking the Cache Dirty Pages Percentage
Reclaiming Space of Unmapped (Unused) LUNs Over time, as servers
connected to a SAN get decommissioned, administrators find an
increasing number of unmapped LUNs, or volumes that are no longer
used by any server. These LUNs, while unused, still occupy disk
space in the disk array. Being able to identify such unmapped LUNs
and reclaim the disk space uselessly consumed by these LUNs will
help administrators avoid unnecessary upgrades and extensions of
their disk arrays.
56Reporting a Disk Space Consumption
BMC Performance Manager Express for EMC Disk Arrays
Version 2.0.01
Reporting a Disk Space Consumption Making sure that a disk array
has enough remaining disk space available is critical for several
reasons:
· SAN administrators want to make sure to be able to provision disk
space for new servers when requested, as quickly as possible.
· The disk array itself may need additional disk space for specific
features to work properly, like automatic snapshots, mirroring,
etc.
· If thin provisioning is used, the remaining disk space becomes
dramatically critical since the inability to allocate additional
space to a LUN when requested by the subscriber host will lead to
catastrophic data loss and corruption.
The disk space used is permanently monitored for each storage pool.
The Subscribed Capacity parameter of the Pool class represents the
amount of disk space that has been made available to the subscriber
hosts, or in other words, the amount of disk space that is seen by
the servers connected to disk array.
The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class
represents the actual space usage in the storage pool. For thin
pools (when thin provisioning is enabled on the disk array), this
value is normally lower than the Subscribed Capacity, as it is the
main purpose of thin provisioning. For traditional pools, the
Consumed Capacity parameters has the same value as the Subscribed
Capacity parameter, as the entirety of the subscribed disk space is
fully allocated in the storage pool.
The Consumed Capacity Percentage parameter is the most critical one
as a storage pool usage nearing 100% means that SAN administrators
will not be able to create new LUNs in the storage pool. By
default, no alarm or warning threshold is set on this parameter as
the fullness of a storage pool may be a normal situation. However,
you can set alert thresholds on this parameter as it fits your
needs.

Report – Disk Space Consumption
Reporting the Total Traffic on an Hourly or Daily Basis BMC
Performance Manager Express for EMC Disk Arrays not only monitors
the traffic and activity of the disk array, controllers, LUNs and
physical disks in MB/sec, but also in GB per hour or per day. The
exact amount of data that was read or written to the disk array,
LUN or physical disk is calculated for each hour of the day and
each day of the week.
Each data rate parameter in MB/sec is accompanied by a non-rate one
in GB. These parameters are “cumulative”: their instantaneous value
has no meaning and they need to be visualized in a long period of
time. (instead of Read Byte Rate or Write Byte Rate).

Viewing the Overall Activity of a Disk Array In order to visualize
the activity of a disk array, use the Read Byte Rate and Write Byte
Rate of the SEN_EMC_ARRAY class. These parameters represent the
overall traffic in megabytes per second for each monitored array,
or more precisely, each EMC disk array that is exposed through the
EMC SMI-S Provider (see the EMC_SMI-S_Provider section of the
Installation Guide for more information about the EMC SMI-S
Provider).
