When You Power Off Network Relay Devices
If you want 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 (i.e., 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, please 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.
