For mirror volumes, data can be backed up through snapshot by slice detachment during the services operation.
To secure consistency of data in a detached slice, the services must be stopped temporarily when detaching the slice.
See
For details on snapshots by slice detachment, see "1.3.8 Snapshots by Slice Detachment."
For securing consistency of snapshot data, see "3.17 Ensuring Consistency of Snapshot Data."
Note
Use Conditions on Snapshot by Slice Detachment
Slices can be detached only from mirror volumes with physical slices. In other words, if disks are not connected directly to mirror groups, creation of snapshots by slice detachment is impossible. Additionally, this snapshot is impossible with mirror volumes in the root class.
Information
Restore
When data is restored back to a volume using data backed up in this procedure, data is restored for the access path to that volume, /dev/sfdsk/class_name/dsk/volume_name. For details, see "7.10.2.1 Without Using GDS Snapshot."
