3.9.1.3 Modify a Volume

An Exascale block volume is an arbitrary-sized allocation of storage space, which can be used as an Exascale Direct Volume (EDV) attachment or iSCSI target.

To modify an existing Exascale block volume, use the ESCLI chvolume command and specify:

• The volume identifier. You can use the lsvolume command to find the identifier for each volume.

• The attributes that you want to change.

For example:

• The following command sets the size of the specified volume to 200 GB:

  @> chvolume 2:50e52177583f4be4bad68ac20b65001e --attributes size=200g

• A volume can have up to two owners. The following command sets scott as the sole owner of the specified volume:

  @> chvolume 2:50e52177583f4be4bad68ac20b65001e --attributes owners=scott

• The following command adds peter as an owner of the specified volume:

  @> chvolume 2:50e52177583f4be4bad68ac20b65001e --attributes owners=+peter

• The following command removes dave as an owner of the specified volume:

  @> chvolume 2:50e52177583f4be4bad68ac20b65001e --attributes owners=-dave
