HP StorageWorks XP Remote Web Console Software - Manual (Page 155)

4. Power off the secondary storage system as described previously.
5. Power on the secondary storage system.
6. If the secondary storage system is ready to resume remote copy operations, power on the
primary storage system.
7. If the primary storage system is ready to resume remote copy operations, resume the data
volume pairs that have been split at the primary storage system. Confirm that the status of the
data volume pairs is changed to Pending or Duplex.
NOTE: After you turned the power on or off at both the primary and secondary storage system
at the same time, if the status of a data volume pair of the primary storage system is Suspend and
the status of a data volume pair of the secondary storage system is Duplex, you must suspend the
data volume pair of the secondary storage system by using Remote Web Console. After confirming
that the statuses of the data volume pair of the primary storage system and secondary storage
system are Suspend, restore the data volume pair that has been split at the primary storage system.
Powering 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 Suspend.
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 Pending or
Duplex. This operation must be performed at the primary site.
Powering On the Primary Storage System
An error may occur if you perform operations on the Universal Replicator for Mainframe pairs
within five minutes after the Ready lamp turns on. In addition, the Universal Replicator for Mainframe
pairs could be suspended due to a failure if the storage system accepts the write I/O to primary
data volumes in Duplex status within five minutes after the Ready lamp turns on.
Removing the Relationship Between the Primary and the 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 Universal Replicator for Mainframe volume pairs have been deleted.
2. Ensure that the Remote Web Console main window is in Modify mode.
For detailed information about how to do this, see the HP XP24000/XP20000 Remote Web
Console User's Guide.
3. Ensure that the DKC Operation window is displayed.
4. In Display, select DKC.
5. Select LDKC from the tree.
The list displays a list of remote storage systems.
6. Select and right-click the remote storage system(s) from the list.
7. Select DKC Operation and Delete DKC from the pop-up menu.
A confirmation message appears.
8. Click OK to close the message.
