Removing LUNs
This section describes the process to remove a LUN from a Core configuration. This process requires actions on both the Core and the server running at the branch.
In the following example procedure, the branch server is assumed to be a Windows server; however, similar steps are required for other types of servers.
1. At the branch where the LUN is exposed, power down the local Windows server. If the Windows server runs on ESXi, you must also unmount and detach the LUN from ESXi.
2. At the data center, take the LUN offline in the Core configuration.
3. Enter the storage lun remove command.
-or-
Choose Configure > Manage: LUNs to open the LUNs page, locate the LUN configuration in the list, and click the trash icon.
If the LUN is in a degraded state (which is not offline), use the force command to remove the degraded online LUN.
