storage-volume unclaim

Unclaims the specified previously claimed storage volumes.

Contexts

All contexts.

In /clusters/cluster/storage-elements/storage-volumes context, command is unclaim.

Syntax

storage-volume unclaim

[-b|--batch-size] integer 


[-d|--storage-volumes]path, [path...]


[-r|--return-to-pool]

Arguments

Required arguments
[-d|--storage-volumes]path, [path...] * Specifies the storage volumes to unclaim.
Optional arguments
[-b|--batch-size]integer Specifies the maximum number of storage volumes to unclaim at once.
[-r|--return-to-pool] Returns the storage capacity of each VIAS-based volume to the pool on the corresponding storage-array.

* - argument is positional.

Description

Use the storage-volume unclaim command to return the specified storage volumes to the unclaimed state.

The target storage volume must not be in use.

NOTE When you use the storage-volume unclaim command with VIAS based storage volumes, the command removes the storage volumes from metro node and they are no longer visible. When you use the command with non VIAS based  storage volumes, the command marks the storage volumes as unclaimed. This is the intended behavior.

Unclaim a thin storage volume

When a storage volume is unclaimed, the thin-rebuild attribute is set to false.

NOTE The thin-rebuild attribute can only be modified for storage volumes that are either claimed or used. When the unclaimed storage volume is claimed and its state is claimed or used, use the set command to modify the thin-rebuild attribute.

Example

In the following example:

  • The ll command in storage-volumes context displays storage volumes, including their use state,
  • The storage-volume unclaim command unclaims two claimed volumes: 
    VPlexcli:/clusters/cluster-2/storage-elements/storage-volumes> ll
VPlexcli:/clusters/cluster-2/storage-elements/storage-volumes> unclaim -d Basic_c1_ramdisk_100GB_686_See also
