Forcing a Primary Logical Drive to Change to a Secondary Logical Drive

Select Yes on the Change to Secondary - Error dialog to force the software to promote the selected primary logical drive to a secondary role.

Consider using this option when you want to perform a role reversal and a communication problem between the local and remote sites is preventing the promotion of the secondary logical drive at the remote site. When the communication problem has been resolved, there will be a Dual Secondary error condition. Use Recovery Guru to recover from this error.

Caution:

When the local primary logical drive becomes a secondary logical drive, any hosts that are accessing the logical drive through a logical drive-to-LUN mapping will not be able to read or write to the logical drive. The other logical drive in the Remote Mirror also has a secondary role, so the mirrored data will not be host-accessible on either side.

Important: To avoid the Dual Secondary error condition and subsequent recovery steps, wait until the connection between the storage subsystems is operational to perform the role reversal.
