When Switching Power Off - HP XP P9500 User Manual

When switching power off

During pair operations, when you switch off the power-supply for the system, ensure the following:
Complete processing for an At-Time Split operation before switching off the power supply.
If this is not done and the status of some of the pairs in the consistency group is changed but
not others, the At-Time Split processing may not resume when you power-on the power supply.
The status of some pairs may remain unchanged.
