HP XP RAID Manager Software - Manual (Page 42)

Do not edit the configuration definition file while RAID Manager is running. Shut down RAID
Manager, edit the configuration file as needed, and then restart RAID Manager.
Do not mix pairs created with the “At-Time Split” option (-m grp) and pairs created without this
option in the same group defined in the RAID Manager configuration file. If you do, a pairsplit
operation might end abnormally, or S-VOLs of the P-VOLs in the same consistency group (CTG)
might not be created correctly at the time the pairsplit request is received.
