Notes:
- When you use an S-VOL of an SI
pair as the P-VOL of a Thin Image Advanced pair, you must create the SI pair first and then create the Thin Image Advanced pair.
- After issuing the raidcom modify snapshot -snapshot_data
split command for a Thin Image Advanced pair for which a consistency group is configured,
verify that the status of all pairs in the Thin Image Advanced consistency group
is PSUS or unpaired, and then execute the SI task. If you do not, the Thin Image Advanced snapshot data and P-VOL data when the VSP 5000 series storage system accepted
the raidcom modify snapshot -snapshot_data split command will
not be consistent. For
details about Thin Image Advanced pair status and operations, see the Hitachi Thin
Image Advanced User Guide
- When the host accesses the Thin Image Advanced S-VOL, the Thin Image Advanced P-VOL data might be used to return a reply. For this
reason, you cannot Quick Restore to exchange the SI P-VOL and S-VOL (which is the Thin Image Advanced P-VOL).
