1.
Locate a CG number that is not being used by a pair.
2.
Specify the CG number explicitly.
3.
You can now run the Paircreate command on the host server.
•
If you are using a Cnt Ac-J S-VOL as an BC P-VOL and you are using RAID Manager to run
commands and the status for some pairs that are assigned to a CG are not changed, some
pairs remain unsplit in the CG and pair consistency is not guaranteed after you run the following
command:
pairsplit
The following are possible reasons why the status for some pairs that are assigned to a CG
are not changed:
◦
The Cnt Ac-J pair is assigned to a CG and the P-VOL and S-VOL have the same contents.
The journal volumes for this pair are full.
◦
The BC license is invalid.
◦
The BC pair volumes are blocked.
◦
The BC pair is in a status that does not allow you to run the pairsplit RAID Manager
command.
For more information about pair status, see
“Monitoring BC pair activity and status”
◦
The BC pair is a part of cascaded pairs and the other pairs in the cascaded pairs are in
a status that does not allow you to split the pairs.
For more information about L1 and L2 pair status and the pair tasks that you can perform
on cascaded pairs, see
“L1, L2 pair status and supported pair user tasks” (page 65)
◦
You are using a BC pair volume in a Cnt Ac-S or Cnt Ac-J pair and the Cnt Ac-S or Cnt
Ac-J pair is in a status that does not allow you to run the pairsplit RAID Manager
command.
If you cannot change the status, the Pairsplit RAID Manager command can end abnormally
with the error code EX_EWSTOT, which indicates timeout occurrence. You cannot change the
pair status during a timeout.
Remove these factors then complete the following:
1.
Resynchronize the pairs. To do this, run the following RAID Manager command:
pairresync
2.
Split the pairs. To do this, run the following RAID Manager command:
Pairsplit
