Notes on using Thin Image primary volumes as TrueCopy or Universal Replicator pair volumes

The raidcom modify snapshot -snapshot_data create CCI command might return the error code EX_EWSTOT (timeout) and terminate abnormally when the status of a pair in an HTI consistency group cannot be changed.

Following are possible reasons why the pair status cannot be changed.

• The HTI primary volume is used as a UR S-VOL, and you are reaching the UR journal volume capacity limit.

• The HTI license is invalid.

• The HTI pair volumes are blocked.

• The current status of the HTI, SI, TC, or UR pair does not allow the raidcom modify snapshot -snapshot_data create to run on the pair.

After resolving these error conditions, make sure that all pairs in the consistency group are in “PAIR” status before running the raidcom modify snapshot -snapshot_data create command again.
