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.

To power off the primary and secondary arrays at the same time, see ”

When powering off secondary arrays
To power off the secondary 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 secondary array, contact your HP account support representative and ask
them to power off the array.
If data volume pairs are split and the secondary array is powered off as mentioned above, use the
following procedures to resume remote copy operations:
1.
Power on the secondary array.
2.
If the secondary 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 secondary array can issue read journal
commands to the primary array.
NOTE:

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.
1.
Split data volume pairs that are affected by powering off the primary and secondary arrays. For
example, if two primary arrays and one secondary array are connected to each other and you want to
power off one of the primary arrays and the secondary array, split data volume pairs defined between
the remaining one primary array and primary array, because these data volume pairs are affected by
powering off of the arrays.
2.
After splitting the pairs finishes, confirm that the status of all pairs is changed to PSUS at the primary
array.
3.
Power off the primary array as described in ”

5.
Power on the secondary array.
6.
If the secondary array is ready to resume remote copy operations, power on the primary array.
7.
If the primary array is ready to resume remote copy operations, resume data volume pairs that were
split at the primary array. Confirm that the status of data volume pairs changed to COPY or PAIR.
