Delete LUN
Note If a LUN is part of an asynchronous replication pairing, it cannot be deleted until the pairing is removed.
To remove the pairing, go to the Async Replication > Pairings menu (see Chapter 5, “Asynchronous
Replication”).
Note You must delete all associated snapshots before a LUN can be deleted.
Tip During the LUN deletion process, GUI performance may be negatively affected until the process
completes. The larger the LUN, the more time the process may take. We recommend deleting larger
LUNs during off-peak hours.
To perform the LUN deletion:
Step 1 Choose LUN Configuration > LUNs.
The LUN window appears.
Step 2 Highlight a LUN from the LUNs list by mousing over it and right click.
The right-click menu appears
Step 3 Choose the Delete menu option.
A delete confirmation dialog box appears.
Step 4 Click Delete or click Cancel and return to the LUNs list.
LUN Mirror
LUN Mirroring is a mapping that maintains two identical data copies. Mirrored LUN are often used to
achieve better availability and to provide a degree of fault tolerance. Data is written to both LUNs
simultaneously. Should one of the LUN drives fail or becomes unavailable; the system continues to
operate using the unaffected drive.
Note • A LUN with an existing Snapshot cannot be setup as a LUN mirror Source.
• LUN with a Snapshot schedule (but without any snapshots) configured from either SSR cannot be
used as a LUN mirror Source.
• Simultaneous mirror operations are not supported on the Cisco UCS Invicta Scaling System. You
must wait for the operation on one LUN to complete before performing another.
Note The creation or scheduling of a Snapshot is not permitted on a mirrored LUN.
