the SnapShot volumes is SMPL. In the following example, the
group name in the configuration definition file is VG01.
2. Execute paircreate -m grp; then, execute pairevtwait to
verify that the status of each volume is PAIR. For example:
•
3. Execute pairsplit; then, execute pairevtwait to verify that the
status of each volume is PSUS. For example:
•
4. Execute pairdisplay to verify the pair status and the
