HP XP P9500 Storage - Manual (Page 451)

Failover
To perform a failover:
1.
Use Business Continuity Manager to detect whether a HyperSwap has been executed by TPC-R
on the primary host.
2. Check the statuses of copy groups.
•
YKQUERY
3. On the primary host, execute the YKSUSPND FLUSH command for Cnt Ac-J Z copy pairs
between the primary storage system and the remote storage system.
When an I/O error or the SUSPER status (a failure suspension) occurs, you do not need to do
anything.
