Power Off The Primary And Secondary Systems At The Same Time; Power Off Network Relay Devices - HP StorageWorks P9000 User Manual

Power off the primary and secondary systems at the same time

The primary system must be powered off before the secondary system is powered off. When you
are ready to power the systems on, the secondary system must be powered on before the primary
system.
The following is the procedure for powering off the primary and secondary systems at the same
time:
1. Split all pairs that will be affected. For example, if two primary systems and one secondary
system are connected to each other and you want to power off one of the primary system and
the secondary system, you must split the pairs on all three systems since they are all affected.
2. After the pairs are split, confirm that their status is PSUS at the primary system.
3. Power off the primary system.
4. Power off the secondary system.
5. Power on the secondary system.
6. When the secondary system is ready to resume copy operations, power on the primary system.
CAUTION:
Access Journal operations; otherwise the pairs could be suspended with a failure.
7. When the primary system is ready to resume copy operations, restore the pairs that have been
split at the primary system. Confirm that the status of the pairs is changed to COPY or PAIR.
After turning power on or off for both the primary and secondary system at the same time, if pair
status at primary system is PSUS and a status of a pair of secondary storage system is PAIR, use
Remote Web Console to suspend the pair of the secondary system. After confirming that the statuses
of the pair on both systems is PSUS, restore the pair at the primary system.
CAUTION:
and then you turn the power back on, the status of all data volume pairs could be suspended
according to a failure.

Power off network relay devices

To power off a network relay device during copy operations
1. Insure that all pairs or mirrors are split and that the status of all the pairs is PSUS.
2. Power off the device.
3. When ready power on the network relay device.
4. When the network relay device is ready for copy operations, from the primary storage system,
restore the pairs that have been split.
5. Confirm that pair status is COPY or PAIR.
92 Maintaining the system
Wait five (5) minutes after powering on a system before performing Continuous
If you turn the power off without changing the status of all data volume pairs to PSUS,
