horcm0 11000/udp #Raid Manager instance 0.
2. Use the ioscan command to determine what devices on the P9000 or XP disk array have
been configured as command devices. There must be two command devices; a primary
command device and a secondary command device.
3. Copy the default Raid Manager configuration file to an instance-specific name:
# cp /etc/horcm.conf /etc/horcm0.conf
4. Create a minimum Raid Manager Configuration file by editing the following fields in the file
created in the previous step:
HORCM_MON Enter the host-name or IP address of the system on which you are editing and
the UDP port number specified for this Raid Manager instance in the /etc/
services file.
For example:
HORCM_MON
# ip_address service poll(10ms) timeout(10ms)
NodeA horcm0 1000 3000
HORCM_CMD Enter the primary and alternate link device file names for both the primary
and redundant command devices (for a total of four raw device file names).
For example:
HORCM_CMD
# dev _name dev _name dev _name
/dev/rdsk/c6t12d0 /dev/rdsk/c9t12d0
5. If the Raid Manager protection facility is enabled, export the HORCPERM environment
variable to the pathname of the HORCM permission file:
# 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 on 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:
# export HORCMPERM=MGRNOINST
6. Start the Raid Manager instance by using horcmstart.sh:
#horcmstart.sh 0
7. Export the environment variable that specifies the RAID Manager instance to be used by the
RAID Manager commands:
#export HORCMINST=<instance_number>
For example:
# export HORCMINST=0
8. Use the Raid Manager commands to obtain information about the disk groups. Verify the
software version of the Raid Manager and the firmware version of the P9000 or XP disk array:
#raidqry –l
To view a list of the available devices on the disk arrays use the raidscan command. The
raidscan command must be invoked separately for each host interface connection to the
disk array. For example, if there are two Fibre Channel host adapters:
#raidscan -p CL1-A
#raidscan -p CL1-B
Unless the devices have been previously paired either on this or another host, the devices will
show up as SMPL (simplex). Paired devices will show up as PVOL (primary volume) or SVOL
