Description
The ssa_make_copy command creates copy volume groups via the following process:
1. The command checks whether you can copy all or part of the volume group.
v
If you want to copy a whole volume group, the command checks whether all the
hdisks in the volume group are RAID-1 or RAID-10 arrays. If any hdisk is of the
wrong type, the command displays a warning, then stops.
v
If you want to copy logical volumes or file systems, the command checks
whether all the logical volumes are in the same volume group, and whether all
the hdisks that make up the volume group are RAID-1 or RAID-10 arrays. If any
logical volume is not in the required volume group, or if any hdisk is of the
wrong type, the command displays a warning, then stops.
Notes:
a. If any hdisk in that is the volume group does not contain a logical volume, that
hdisk is not copied.
b. If active paging space exists on the volume group, you cannot copy any part of
the volume group. For a copy of a volume group to be uncoupled, I/O
operations must be temporarily stopped. I/O operations cannot be stopped for
active paging space.
