Typically, you deny access to a storage pool when you no longer want to use the storage pool with the local NAS server or cluster.  If you want to use the storage pool with another NAS server or cluster, refer to the Command Line Reference for the span-assign-to-cluster command, or view the span-assign-to-cluster man page for information on migrating a storage pool safely.

Denying access to a storage pool:

  • Unloads the storage pool and its file systems from memory, so that they do not appear in the NAS Manager list of storage pools or in the results of the span-list -f command.

  • Unlicenses the host SDs.

  • Deletes all the non-volatile memory contents for all file systems in the storage pool.

    CAUTION:
    If a file system did not unmount cleanly before access to the storage pool is denied, all data written by clients and acknowledged by the server, but not yet been written to the storage, will be lost.
  • Removes all file system to EVS bindings. If you later allow access to the storage pool, you will need to assign each file system to an EVS, either using NAS Manager or using the evsfs add command.

Note: Denying access to a storage pool does not delete the storage pool, the file systems, or the SDs.
  1. Navigate to Home > Storage Management > File Systems to display the File Systems page.


  2. Identify the file systems in the storage pool to which you want to deny access, then select those file systems.
    To select a file system, select the check box next to the file system label.
  3. Unmount the selected file systems.
    Click unmount, and in the confirmation dialog, click OK.
  4. Click the Storage Pools shortcut to display a list of all pools, select a particular storage pool, and click Deny Access; in the confirmation dialog, click OK.
    Note: This will also remove the pool from the storage pools list, but it will not be deleted.
