Remove Drive Enclosure
Overview
This function removes a Drive Enclosure (DE) without stopping the storage system.
After the target DEs are isolated, remove these DEs from the storage system.
Perform the start maintenance operation by using the [Start/End Maintenance] function before the removing task. If the operation has not been performed, the removal cannot be started.
When DE hot removal is performed, multiple DEs can be removed with a single operation.
Note that multiple DEs can only be removed when they are allocated to the same SAS cascade configuration (*1). Multiple DEs that are allocated to different SAS cascade configurations cannot be removed. Refer to "DEs on the Same SAS Cascade" for details.
*1 : "SAS cascade" refers to DEs that are attached to one DI port. The DEs that are sequentially located from the terminal DE in each SAS cascade configuration can be removed.
2.5" DEs, 3.5" DEs, and 3.5" high density DEs can be removed at the same time.
- This function cannot be used under the following conditions:
-
Drives in the DE, which is to be removed, are registered in the RAID groups, the hot spares, the Thin Provisioning Pools, the Flexible Tier Pools, the REC Disk Buffers, or the Extreme Cache Pools.
- The status of the DE below is "Undefined"
