Suspending a Mirrored Pair

Use the Suspend Mirrored Pair dialog to suspend data transfer between a and a that are participating in without removing the mirror relationship.

The Suspend option lets you control when the data on the primary logical drive and the secondary logical drive should be synchronized. This option helps to reduce any performance impact to the host application that might occur while any changed data on the primary logical drive is copied to the secondary logical drive.

When a remote logical drive mirror is in a Suspended status, no attempt is made to contact the secondary logical drive. Any writes to the primary logical drive are persistently logged in the mirror repository logical drives. After the mirrored pair is resumed, only the modified regions of the primary logical drive are written to the secondary logical drive.


Attention:

Possible loss of data access – If the selected mirrored pair is part of a global mirror group, you will automatically suspend all mirrored pairs in the global mirror group. Use the command line interface to resume single write-consistent mirrored pairs.

Keep these guidelines in mind when you suspend a mirrored pair:

  1. Select Logical Drive >> Enhanced Remote Mirroring >> Suspend .
  2. In the Suspend Mirrored Pair dialog, select one more mirrored pairs to be suspended. To suspend multiple mirrored pairs, select the primary logical drive or the secondary logical drive in the Mirrored pairs area.
  3. Click Suspend.
  4. In the Suspend Mirrored Pair - Confirmation dialog, type yes in the text box, and click OK.
  5. When the selected mirrored logical drives have been suspended, in the Suspend Mirrored Pair - Progress dialog, click OK.
    The Subsystem Management Window appears, and the primary logical drive and the secondary logical drive appear with an Optimal/Suspended status.
