HP P9000 RAID Manager Reference Guide (T1610-96037, October 2011)

DescriptionOption
Shuts down HORCM.-S
Displays the command device name currently used by HORCM. If the command device is blocked
due to online maintenance (microcode replacement) of the storage system, you can check the
command device name in advance using this option.
-D
Changes the command device name being used by HORCM and displays the new command device
name. If the command device is blocked due to online maintenance (microcode replacement) of the
storage system, you can change the command device in advance using this option.
-c
NOTE: horcctl -D -C command designates a protection mode command device by adding ‘*’ to
the device file name as follows:
HP-UX example with command device security:
# horcctl -D
Current control device = /dev/rdsk/c0t0d0*
"horcctl -DI" command shows the number of RM instances of when HORCM has being started as
follows:
HP-UX example without command device security:
# horcctl -DI
Current control device = /dev/rdsk/c0t0d0 AI = 14 TI = 0 CI = 1
where
AI : NUM of actual instances in use
TI : NUM of temporary instances in RAID
CI : NUM of instances using current (own) instance
Used when specifying the unit ID of a command device as the target. This option is effective when
the -D or -C option is specified. If this option is not specified, the unit ID is 0.
-u <unitid>
Displays the network address and port name being used by HORCM. The -g <group> option is used
when specifying the group name defined in the configuration definition file.
-ND -g <group>
Changes the network address and port name being used by HORCM and displays the new network
address name. The -g <group> option specifies the group name defined in the configuration definition
file.
-NC -g <group>
horctakeoff
This is a scripted command for executing several HORC operation commands combined. It checks
the volume attribute (optionally specified) and decides a takeover action. The horctakeoff operation
is defined to change from 3DC multi-target to 3DC multi-hop with the state of running APP, after
that the horctakeover command will be able to configure 3DC multi-target on the remote site without
stopping the APP. The granularity of either a logical volume or volume group can be specified with
this command.
