the pair status. For details, see View Pair Synchronization Rate window on
page 239.
(VSP G1000, G1500, and VSP F1500) If you cannot delete Thin Image pairs
with Device Manager - Storage Navigator, you can use CCI commands to
forcibly delete all Thin Image cascaded pairs in a snapshot tree. For details
about CCI commands, see
Pair tasks using CCI or Device Manager - Storage
Navigator on page 212 and the Command Control Interface Command
Reference.
Note: After deleting a Thin Image pair, the number of pairs shown in the
summary section in the Local Replication window and in the list on the TI
Root Volumes tab can be different. Wait until the configuration has completed
processing. If the numbers do not match, reload the configuration
information (see
Reloading Thin Image configuration information on
page 128).
Note: If the amount of snapshot data in selected P-VOLs or the total number
of pairs in selected snapshot groups exceeds 37,768, an error message
appears when attempting to perform pair tasks.
Before you begin
• You must have the Storage Administrator (Local Copy) role.
