Connecting The Disk Array; Verifying Host Recognition Of Disk Array Devices; Configuring Disk Array Devices - HP StorageWorks P9000 - Disk Arrays Configuration Manual

Connecting the disk array

The HP service representative performs the following steps to connect the disk array to the host:
1. Verifying operational status of the disk array channel adapters, LDEVs, and paths.
2. Connecting the Fibre Channel cables between the disk array and the fabric switch or host.
3. Verifying the ready status of the disk array and peripherals.

Verifying host recognition of disk array devices

1. Log into the host as an administrator (root).
2. If the disk array LUNs are defined after the IBM system is powered on, issue a cfgmgr command
to recognize the new devices.
3. Use the lsdev command to display system device data and verify that the system recognizes
the newly installed devices.
The devices are listed by device file name. All new devices should be listed as Available. If they
are listed as Define, you must perform additional configuration steps before they can be used.
The following example shows that the device hdisk0 is installed on bus 60 and has TID=5 and
LUN=0:
#lsdev -Cc disk
hdisk0 Available 10-60-00-5, 0 16 Bit SCSI Disk Drive
hdisk1 Available 10-60-00-6, 0 16 Bit SCSI Disk Drive
4. Record the device file names for the new devices. You will use this information when you change
the device parameters. For information about changing the device parameters, see
the device
5. Use the lscfg command to identify the AIX disk device's corresponding array LDEV designation.
For example, enter the following command to display the emulation type, LDEV number, CU
number and array port designation for disk device hdisk3.
# lscfg –vl hdisk3

Configuring disk array devices

Disks in the disk array are configured using the same procedure for configuring any new disk on the
host. This includes the following procedures:
Changing the device parameters
Assigning the new devices to volume groups
Creating the Journaled File Systems
Mounting and verifying the file systems
Creating scripts to configure all devices at once can save you considerable time.
