Monitoring TC operations history

You can review a pair's history of operations, including the operation's description, date and time it took place, primary and secondary system information, and other details.

Procedure

  1. Click Storage Systems, and then expand the Storage Systems tree.

  2. In the Storage Systems tree, click Replication.

  3. In the Replication window, click View History Remote Replication.

  4. In the History window, for Copy Type, select TC. The Description column displays operations, which are explained below.

Results

Note the following when viewing histories:
  • Operation rows might not appear in descending, chronological order.
  • The most recent operations are displayed up to a maximum of 524,288 (8,192 for VSP Gx00 models and VSP Fx00 models) operations. Information older than seven days is not shown.
  • "LDEV ID" indicates the physical LDEV ID, even when you use CCI and use pair volumes in a virtual storage machine.
  • If a failed split occurred with two or more LDEVs at the same time, the number of pairs showing Pair Suspend (Failure) might not match the actual number of pairs in which the failure occurred.
  • If you use 1,000 or more pairs concurrently, some operation history might not be recorded.
