Delete LUN

If a LUN is part of an asynchronous replication pairing, it cannot be deleted until the pairing is removed.
Note
To remove the pairing, go to the Async Replication > Pairings menu (see
Replication").
You must delete all associated snapshots before a LUN can be deleted.
Note
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.

Step 2

Choose the Delete menu option.

A delete confirmation dialog box appears.
Click Delete or click Cancel and return to the LUNs list.
Step 4

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.

•
The creation or scheduling of a Snapshot is not permitted on a mirrored LUN.
Note
Create LUN Mirror
To create a LUN Mirror, do the following:
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.
