NOTE:

If you are performing the pairsplit operation on a pair that shares the same P-VOL, do

not run the pairresync -restore command on the pair. Running the command during this
operation can result in the pairsplit operation ending abnormally.

Prerequisite information

The pair status must have a status of “PAIR”.

If you pair a P-VOL with two or more V-VOLs, the pairs must have a status other than “RCPY”.
If the status is “RCPY”, the pairsplit operation can end abnormally.

SS does not support Quick Split mode.

Splitting pairs

You can also split pairs in consistency groups.

For more information about splitting pairs in a consistency group, see

Splitting pairs in consistency groups at a pre-determined time

Use the At-Time Split operation to split pairs in a consistency group at a pre-determined time.

Prerequisite information

The RAID Manager must be installed.

1.

From a command prompt, run the following command, specifying a consistency group number
in the command option:

paircreate

The At-Time SS function is enabled.

2.

(Optional) Create more pairs specifying the same consistency group number.

3.

From a command prompt, run the following command on the consistency group:

pairsplit

The P9500 storage system receives the command. Running a subsequent write requests from
the host to the P-VOL of a pair in the consistency group acquires SS data.
