DB admin login required
Command Line
Find the storage vendor and LUN (df –k and the Solaris format utility)
Root login required. Different for each operating system
HBA or O/S utility
Find WWN using LUN Different for each HBA
Storage GUI or CLI

Tool Steps Comments Elapsed Time
Trap collector
Initial traps are recorded. Hundreds of sympathetic alarms are generated equipment in the data path. All affected group leaders are notified. Wait to hear from applications group
Multiple tools may be required including HP OpenView, MicroMuse etc.
Meetings Group leaders and vendors gather to discuss problem
Finger pointing ensues
Visio Diagrams and Excel spreadsheets
Possibly outdated information is used to try to isolate problem
Tribal knowledge rules
Manual
Physical verification
Teams are dispersed through out the data center to check on their respective domains and isolate the problem
Time consuming, especially if multiple data centers are involved.
Approximately four hours – Extreme cases could days
Automated Database
module
Receive alarms and quickly indicate source of problem and application affected

SMI-S in SRM Solutions
SMI-S compliant SRM solutions provide the following benefits:
Agent less management of Windows infrastructureNormalized management for all storage systems, switches and hostsDevice support added quickly, without “shims” or “translators” to proprietary interfaces CIM-standard database schema, instead of a proprietary data model, results in faster administrator ramp-up and less risk of vendor lock-in.

Lessons Learned
Management support and endorsement at the executive level plays a crucial role
In successful deploymentsIn enabling the savingsCritical to get all domain experts on-board
Storage admins, DBAs, system admins, Exchange admins
Move from a culture of provisioning to a culture of managementDriving up utilization requires performance managementUse SRM to create baseline for IT initiatives
Use reports to communicate success of IT initiativesSMI-S compliance reduces risk and increase choicesThe tools are available today - pick one and get started
