Dell EMC Solutions Enabler 9.2 SRDF Family CLI User Guide

Optionally, you can release the device external locks held in the array for a terminated SRDF/AR session.

Locks may need to be released manually if a session is terminated unexpectedly due to a system crash or component failure. Device locks for a terminated session can be released manually for a device group, composite group or log file without restarting the session.

Syntax

Use the symreplicate release command to release any device external locks associated with devices in the specified device group that are still held from when they were locked from the terminated SRDF/AR session.

Restrictions

• The SRDF/AR session for the targeted devices must not be active.
• Devices must have been locked by the previous session and the lock holder ID must match the previous session's ID.
• The number of devices to be unlocked must be less than or equal to the total number of devices in the previous SRDF/AR session.

  The force (-force) option is required to release device locks in the following situations:

• If the release action is requested in a clustered SRDF/AR environment on a host that did not initiate the session and the status of the session cannot be determined.
• If any of the devices' lock holder ID in the targeted SRDF/AR session do not match the session's lock hoder ID, and the user wants to release the devices locked with the session's lock holder ID.
• If the lock holder ID for some devices in the targeted SRDF/AR session do not match the lock holder ID of that session, and the user wants to release the devices locked with the session's original lock holder ID.

Example

To release devices locks on a terminated session for device group prod on array 35002:

symreplicate -g prod release -sid 35002
