Building Disaster Recovery Serviceguard Solutions Using Metrocluster with Continuous Access XP P9000 for Linux B.12.00.00

NOTE: The device file name specified for the command device must be a persistent device
name. You can use udev rule to create a persistent device name for the command device.
For Example:
Create the following rule file in udev rules directory (/etc/udev/rules.d):
# cat /etc/udev/rules.d/<user defined name>.rules
KERNEL=="sd*", SUBSYSTEM=="block", ENV{DEVTYPE}=="disk",
ENV{ID_SERIAL}== “ <command device wwn id >“ ,
SYMLINK+="xp/disks/dsk1", OWNER="root", GROUP="disk", MODE="0660"
Reload the rules using the udevadm command:
# udevadm trigger
6. If the Raid Manager protection facility is enabled, set the HORCPERM environment variable to
the pathname of the HORCM permission file, then export the variable.
For example:
# export HORCMPERM=/etc/horcmperm0.conf
The RAID Manager protection facility restricts volume control operations to volumes that the
host is allowed to see, with or without host-based LUN security and to volumes that are listed
in the configuration file.
For more information about RAID Manager protection facility, see HP StorageWorks P9000
RAID Manager User's Guide or HP StorageWorks XP RAID Manager User's Guide available
at http://h20000.www2.hp.com/bizsupport/TechSupport/Home.jsp.
If the Raid Manager protection facility is not used or disabled, export the HORCPERM
environment variable to MGRNOINST.
For example:
# export HORCMPERM=MGRNOINST
7. Start the Raid Manager instance by using horcmstart.sh <instance-#>
# horcmstart.sh 0
8. Export the environment variable that specifies the Raid Manager instance number to be used
by the Raid Manager commands.
For example:
# export HORCMINST=0
Now, use Raid Manager commands to get further information from the disk arrays. To verify
the software revision of the Raid Manager and the firmware revision of the XP or P9000 disk
array, run the following command:
# raidqry -l
NOTE: Verify for the minimum requirement level for XP or P9000, Raid Manager software,
and firmware for your version listed in the Metrocluster with Continuous Access XP P9000 for
Linux Release Notes.
Identifying Linux device files
Before you create volume groups or disk groups, you must determine the device files of the
corresponding LUNs used in the P9000 array. To determine the device files corresponding
to the LUNs in the P9000 array, run the following command:
# ls /dev/sd* | raidscan -find -fx
The following output is displayed
DEVICE_FILE UID S/F PORT TARG LUN SERIAL LDEV PRODUCT_ID
