In HDvM - SN, you can review the history of operations for a pair, including the operation's description, date and time it took place, primary and secondary system information, and other details.
-
In the
History window, for
Copy Type, select
TC. The
Description column displays operations, which are explained below.
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 (VSP 5000 series) or 8,192 (SVP E series), within the last seven days. If the history information of more than the maximum operations is generated within seven days, the excess information will be deleted in the order from oldest to newest. In addition, whenever the date changes, the information on the oldest date is deleted from the stored information, and the 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.
- You can use audit logs to check the history of TC pair operations. For details, see the Command Control Interface Command Reference.
