data volume pair of the secondary storage system is PAIR, you must suspend the data volume pair
of the secondary storage system by using Remote Web Console. After confirming that the status
of the data volume pair of the primary and secondary storage system is PSUS, restore the data
volume pair that has been split at the primary storage system.
Power Off Network Relay Devices
To power off a network relay device during remote copy operations, you must ensure, before
powering off the device, that all data volume pairs or mirrors (that is, pairs of journal groups) are
split, and that the status of all the data volume pairs is PSUS.
If data volume pairs are split and the network relay device is powered off as mentioned above,
you can resume remote copy operations by taking the following steps:
1. Power on the network relay device.
2. If the network relay device is ready for remote copy operations, restore the data volume pairs
that have been split, and then confirm that the status of the data volume pairs is COPY or PAIR.
This operation must be performed at the primary site.
Turning Power On
This section explains what should be noted when you power on the storage systems.
Power On the Primary Storage System
An error may occur if you perform the operations on the XP Continuous Access Journal pairs, within
five minutes, because the Ready lamp turns on after you powered on the primary storage system.
In addition, the XP Continuous Access Journal pairs could be suspended because of a failure
caused from the storage system accepting the write I/O to the primary data volumes in PAIR status.
This occurs within five minutes of the Ready lamp being turned on.
Removing the Relationship Between Primary and Secondary Storage
Systems
To remove the relationship between the primary and the secondary storage systems, and then
remove all the logical paths between the two storage systems, both the primary storage system
administrator and the secondary storage system administrator must perform this operation.
1. Make sure that all affected XP Continuous Access Journal volume pairs have been released.
2. Ensure that the Remote Web Console main window is in Modify mode.
For detailed information about how to do this, see the HP StorageWorks XP24000/XP20000
Remote Web Console User Guide.
