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 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.

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.
