HP XP P9500 Storage - Manual (Page 39)

3. Configure the device as needed before setting it as a command device. For example, use
Virtual LUN or Virtual LVI to create a device that has 36 MB of storage capacity. For
instructions, see the HP P9000 Provisioning for Open Systems User Guide.
4. Launch LUN Manager, locate and select the device, and set the device as a command device.
For more information, see the HP P9000 Provisioning for Open Systems User Guide. If you
want to use the RAID Manager Protection Facility, also enable command device security at
this time. For instructions, see the HP P9000 Provisioning for Open Systems User Guide. For
information about the Protection Facility, see the HP P9000 RAID Manager User Guide.
5. Write down the following information about this command device. You will need this
information when you define the command device in the configuration definition file.
6. To set an alternate command device, repeat this procedure for another volume. For information
about alternate command devices, see
“About alternate command devices” (page 40) .
NOTE:
•
For Solaris operations, the command device must be labeled.
•
To enable dual pathing of the command device under Solaris systems, include all paths
to the command device on a single line in the HORCM_CMD section of the configuration
definition file.
Example 1 “Example of alternate path for command device for Solaris
systems” shows an example with two controller paths (c1 and c2) to the command device.
Putting the path information on separate lines may cause parsing issues, and failover
may not occur unless the HORCM startup script is restarted on the Solaris system.
Example 1 Example of alternate path for command device for Solaris systems
HORCM_CMD
#dev_name dev_name dev_name
/dev/rdsk/c1t66d36s2 /dev/rdsk/c2t66d36s2
Setting command device and virtual command device by in-band and out-of-band
methods
For executing a command by the in-band method, set an LU path in a configuration definition file
and create a command device. The command device in the DKC specified by the LU path accepts
the command from the client, and executes the operation instruction.
Meanwhile, for executing a command by the out-of-band method, create a virtual command device.
The virtual command device creates an IP address of the SVP, a UDP communication port number
(fixed at 31001), and a DKC unit number in the configuration definition file.
By creating the virtual command device, transfer the command from the client or the server via
LAN to the virtual command device of the set IP address in the SVP, and assign an operation
instruction to the DKC.
A setting example of a command device and a virtual command device (by the in-band and
out-of-band methods) in a configuration definition file is shown below. For details, see the manual
HP P9000 RAID Manager User Guide.
Example 2 Setting example of command device in configuration definition file (in-band method)
HORCM_CMD
#dev_name dev_name dev_name
\\.\CMD-64015:/dev/rdsk/*

and a DKC unit number 00001 are specified.
