HPE P2000/MSA 2000 SAN Array Systems - How to Decrease Volume Size


The purpose of this document is to explain the procedure of decreasing a volume's size.


As the idea of all MSA storage systems is that the need for capacity will be always increasing, there is no option to shrink a volume or vdisk online. However it might happen that by mistake the capacity gets increased without the need for that. In order to get the volume shrunk, perform the following steps:

  1. Backup the data of the volume.

  2. Unmap the volume.

  3. Delete the volume.

  4. Create a new volume with the desired smaller capacity.

  5. Map it.

  6. Restore the data.

The steps (GUI) and commands (CLI) for implementing the above mentioned action plan can be found in the appropriate guides:
