Syntax; Options And Parameters - HP StorageWorks P9000 - Disk Arrays Reference Manual

the volume pair is deleted, the volumes are returned to the simplex state, and the primary and
secondary volume status is lost. Paired volumes are split as soon as the pairsplit command is issued.
If you want to synchronize the volumes, the pairsplit command must be issued after write I/Os to
the paired volume have completed.
You can create and split Business Copy pairs simultaneously using the -split option of the paircreate
command (see
You can delete pairs by using the -S option of the pairsplit command. When the pairsplit -S command
is issued, the specified Continuous Access Synchronous or Business Copy pair is deleted, and each
volume is changed to SMPL (simplex) mode. If you want to re-establish a pair that has been deleted,
you must use the paircreate command (not pairresync).
Note on Quick Split: If "$HORCC_SPLT=QUICK" environment variable is set (XP24000/XP20000
Disk Array or XP12000 Disk Array/XP10000 Disk Array), the "pairsplit" and "paircreate -split"
operations are performed as Quick Split regardless of the system option mode 122 setting on the
SVP. The $HORCC_SPLT environment variable is ignored by XP1024/XP128 Disk Array.

Options and parameters

Only one pairsplit option (-r, -rw, -S, -R, or -P) can be specified. If more than one option is specified,

Description
Displays Help/Usage and version information.
Terminates the interactive mode and exits this command.
Makes the pairsplit command enter the interactive mode. The -zx option guards performing of the
HORCM in the interactive mode. When this option is specified and detects a HORCM shutdown,
interactive mode terminates.
OpenVMS cannot use the -zx option.
Specifies the command as [HORC]/[HOMRCF] or [Continuous Access Synchronous]/[Business Copy],
and used when specifying the RAID Manager instance number.
Specifies a group name defined in the configuration definition file. This option must always be
specified. The command is executed for the specified group unless the -d <pair Vol> option is
specified.
