When powering off primary arrays
To power off the primary array during remote copy operations, first ensure that all data volume
pairs or mirrors (that is, pairs of journal groups) are split and the status of all data volume pairs is
PSUS.
CAUTION:
To power off the primary array, contact your HP account support representative and
ask them to power off the array.
If data volume pairs are split and the primary array is powered off as mentioned above, use the
following procedure to resume remote copy operations:
1.
Power on the primary array.
2.
If the primary array is ready to resume remote copy operations, restore data volume pairs
that were split, and confirm that the status of the data volume pairs is COPY or PAIR. This
operation must be performed at the primary site.
After taking these steps, remote copy operations resume. The primary array can respond to read
journal commands issued by the secondary array.
NOTE:
To power off the primary and secondary arrays at the same time, see
off primary and secondary arrays at the same time
.
NOTE:
If you turn the power off without changing the status of all data volume pairs to PSUS,
and then you turn the power back on, the status of all data volume pairs could be suspended
according to a failure

When powering off primary and secondary arrays at the same time
To power off the primary and secondary arrays at the same time, you must power off the primary
array before powering off the secondary array. To power on the primary and secondary arrays
again, you must power on the secondary array before powering on the primary array.
