RAID Manager pair commands

To create and manage CA and BC pairs with RM, use the following
commands:

paircreate

Establishes a primary to secondary pair relationship
between volumes. See “paircreate”

(page 138)

.

pairdisplay

Displays the state of volumes. See “pairdisplay”

(page

149)

.

pairsplit

Suspends or deletes a paired volume. See “pairsplit”

(page 177)

.

pairresync

Restores a volume from a PSUE/PSUS/SSWS state to a
PAIR state. See “pairresync”

(page 168)

.

Before issuing RM commands, set the HORCMINST environment
variable to refer to the instance number you want to use for the local RM
instance.

Continuous Access

After installing CA, the system administrator must conduct operation tests
for recovery and maintenance, to check for failures. The HP representative
can identify the possible causes of a failure by using the SVP.

Caution

For CA, make sure to unset the HORCC_MRCF variable. Do not set the
HORCC_MRCF variable to 0.

Business Copy

For BC, set HORCC_MRCF=1.
