Using RAID Manager in a system configuration with the multi-array virtualization
function
To use RAID Manager with the system configuration using the multi-array virtualization function,
the following two methods can be used.
•
Specifying a virtual storage machine to HORCM_VCMD in configuration definition files
•
Specifying a virtual storage machine to command options (i.e., -s <seq#> or -u <unit id>)
If you specify the virtual storage machine to HORCM_VCMD of the configuration file, the user's
shell scripts can be used continuously, because you do not need to modify their scripts. However,
if you define HORCM_VCMD, you cannot operate the virtual storage machine whose the serial
number is not specified by HORC_VCMD. If you specify the virtual storage machine to the command
options (i.e., -s <seq#> or -u <unit id>) instead of specifying with HORCM_VCMD, you can also
operate the virtual storage machine of the serial number not specifying to HORCM_VCMD.
After you change the virtual storage machine configuration with the raidcom add resource command
or the raidcom delete resource command, restart HORCM.
Specifying a virtual storage machine by HORCM_VCMD
Configuration definition file settings when specifying a virtual storage machine by HORCM_VCMD
This topic shows configuration definition file settings with the multi-array virtualization function
when specifying a virtual storage machine by HORCM_VCMD. For details on other parameters,
see
“Configuration definition file” (page 25) .
•
HORCM_CMD
Specify a volume belonging to meta_resource in XP7 as the command device. RAID Manager
obtains the virtual storage machine information defined in XP7 via the specified command
device, and configure the virtual storage machine components. When you specify a volume
in the virtual storage machine as the command device in the system configuration with the
multi-array virtualization function, you cannot start RAID Manager.
•
HORCM_VCMD
In the beginning of HORCM_VCMD, specify a serial number of the virtual storage machine
to be operated by this instance. If you specify the serial number of the virtual storage machine
to HORCM_VCMD, even if you do not specify the command option (i.e., -s <seq#> or -u <unit
ID>), the virtual storage machine of the serial number defined with the beginning of
HORCM_VCMD is operated.
If you define HORCM_VCMD, you cannot operate the virtual storage machines whose serial
numbers are not specified by HORCM_VCMD. When you specify a virtual storage machine
that is not specified with HORCM_VCMD by command options (i.e., -s <seq#> or -u <unit
id>), error occurs. To operate more than one virtual storage machine from a instance, specify
serial numbers of the virtual storage machines with HORCM_VCMD. To operate the virtual
storage machine specified in the second or later of HORCM_VCMD, use the command options
(i.e., -s <seq#> or -u <unit id>).
•
HORCM_LDEV
Specify volumes to be copied. Serial numbers of the virtual storage machine and virtual LDEV
IDs must be specified. You cannot specify the volumes with HORCM_DEV in the system
configuration with the multi-array virtualization function. Specify the volumes with
HORCM_LDEV.
•
HORCM_INST
Specify an IP address and a service name of the remote host as it is for not using the multi-array
virtualization function.
