Changing a Primary Mirrored Logical Drive to a Secondary Logical Drive

Related Topics

Use this option to perform a role reversal between the two paired logical drives in a Remote Mirror . This option demotes a selected primary logical drive to become the secondary logical drive of the mirrored pair. If the associated secondary logical drive can be contacted, the secondary logical drive is automatically promoted to be the primary logical drive. Use this option for role reversals during normal operating conditions. You can also use this option during a Recovery Guru procedure for a Dual Primary Remote Mirror status condition.

Select Yes.

Results:

  • The primary logical drive is demoted to be the secondary logical drive in the Remote Mirror.

Example

The above example of a Logical View shows the Primary Logical Drive Accounting and the Secondary Logical Drive Accounting 2, from a remote storage subsystem.

After selecting the Primary Logical Drive Accounting and using the Change >> Role to Secondary option, the logical drive Accounting is displayed as a secondary logical drive in the Logical View. The (former) Secondary Logical Drive Accounting 2, from a remote storage subsystem, is now the primary logical drive of the Remote Mirror and is no longer displayed in the Subsystem Management Window for Storage Subsystem East.
