2.1 Connecting the AMS2000/SMS100 System to the Red Hat Linux Host
After you prepare the AMS2000/SMS100 system hardware and software and fibre-channel HBA(s), connect the AMS2000/SMS100 system to the Red Hat Linux system. The AMS2000/SMS100 system comes with all the hardware and cabling required for connection to the host system(s).
Table 2-1 summarizes the steps for connecting AMS2000/SMS100 system to the Red Hat Linux system host. Some steps are performed by the Hitachi Data Systems representative, while others are performed by the user.
Table 2-1 Steps for Connecting AMS2000/SMS100 System to a Red Hat Linux Host
Activity Performed by Description
1. Verify AMS2000/SMS100 system installation
Hitachi Data Systems representative
Confirm that the status of the fibre-channel HBA(s) and LDEVs is NORMAL.
2. Shut down the Red Hat Linux system
User Power off the Red Hat Linux system before connecting the AMS2000/SMS100 system.
Shut down the Red Hat Linux system.
When shutdown is complete, power off the Red Hat Linux display.
Power off all peripheral devices except for the AMS2000/SMS100 system.
Power off the host system. You are now ready to connect the AMS2000/SMS100 system.
3. Connect the AMS2000/SMS100 system
Hitachi Data Systems representative
Install fibre-channel cables between the AMS2000/SMS100 system and the Red Hat Linux system. Follow all precautions and procedures in the Adaptable Modular Storage Maintenance Manual/Simple Modular Storage Maintenance Manual. Check all specifications to ensure proper installation and configuration.
4. Power on the Red Hat Linux system
User Power on the Red Hat Linux system after connecting the AMS2000/SMS100 system:
Power on the Red Hat Linux system display.
Power on all peripheral devices. The AMS2000/SMS100 system should be on, and the fibre-channel ports should be configured. If the fibre ports are configured after the Red Hat Linux system is powered on, restart the system to have the new devices recognized.
Confirm the ready status of all peripheral devices, including the AMS2000/SMS100 system
Power on the Red Hat Linux system.
5 Boot the Red Hat Linux system

2.2 Configuring the Host Fibre-Channel HBA(s)
Configure the fibre-channel HBA(s) connected to the AMS2000/SMS100 system. The HBAs have many configuration options. This section provides the following minimum requirements for configuring host fibre-channel adapters for operation with the AMS2000/SMS100 system. For more information, refer to the documentation for your fibre-channel HBA(s).
The queue depth requirements for AMS2000/SMS100 system devices are specified in Table 2-2.
The BIOS might need to be disabled to prevent the system from trying to boot from the AMS2000/SMS100 system.
Several other parameters (e.g., FC, fabric) may also need to be set. Please refer to the user documentation that came with your HBA to determine whether other options are required to meet your operational requirements.
Note: Be sure to use the same settings and device parameters for all AMS2000/SMS100 system devices.
Table 2-2 Requirements for AMS2000/SMS100 System Devices
Parameter Required Value
Queue depth per LU 32 per LU
Queue depth per port (MAXTAGS) 512 per port
Note: You can adjust the queue depth for the AMS2000/SMS100 system devices later as needed (within the specified range) to optimize the I/O performance of the AMS2000/SMS100 system devices.

2.3 Verifying New Device Recognition
The final step before configuring the new AMS2000/SMS100 system disk devices is to verify that the host system recognizes the new devices. The host system automatically creates a device file for each new device recognized.
To verify new device recognition:
1. Use the dmesg command to display the devices (see Figure 2-3).
2. Record the device file name for each new AMS2000/SMS100 system device. You will need this information when you partition the devices (see Verifying Device Recognition by Red Hat Linux). See Table 2-8 for a sample SCSI path worksheet.
3. The device files are created under the /dev directory. Verify that a device file was created for each new AMS2000/SMS100 system disk device (see Figure 2-4).
# dmesg | more::scsi1 : ioc1: LSI53C1030, FwRev=01032700h, Ports=1, MaxQ=255, IRQ=209 Emulex LightPulse Fibre Channel SCSI driver 8.1.10.3 Copyright(c) 2004-2006 Emulex.

In this example, the HITACHI DF600F device (TID 0, LUN 0) and the HITACHI DF600F device (TID 0, LUN 1) are recognized by the Red Hat Linux server.

1. Please gather the backup when “/etc/multipath.conf” already exists.# cp /etc/multipath.conf /etc/multipath.conf.bak
2. Please edit “/etc/multipath.conf” as follows.defaults {

3.1 Partitioning the Devices
After the setting the number of logical units, use the following procedure to set the partitions on the AMS2000/SMS100 system disk devices:
1. Enter fdisk/dev/<device_name>
Example: fdisk/dev/sda
where dev/sda is the device file name
2. Select p to display the present partitions.
3. Select n to make a new partition. You can make up to four primary partitions (1-4) or one extended partition. The extended partition can be organized into 11 logical partitions, which can be assigned partition numbers from 5 to 15.
4. Select w to write the partition information to disk and complete the fdisk command.
Note: Other commands that you might want to use include d to remove partitions or q to stop a change.
Repeat steps 1 through 4 for each new AMS2000/SMS100 system disk device.
