Removing a SANsymphony Storage Class

Follow this process to safely remove a SANsymphony Storage Class from Proxmox VE while ensuring all associated virtual disks and LVM volumes are properly cleaned up.

  1. Detach/remove SANsymphony disks from Virtual Machines
    • Detach and delete any SANsymphony-provisioned disks from virtual machines, or
    • Delete the virtual machines if they’re no longer needed (this also removes referenced/unreferenced SANsymphony disks).
  2. If LVM storage was created on SANsymphony disks, remove it before proceeding.
  3. Run the following interactive command to select and remove virtual disks along with their underlying SANsymphony storage:
      Copy
      Command
      ssy-plugin remove
  4. Optional Manual Cleanup (Not Recommended)
    • You may manually unserve disks from the SANsymphony DataCore Management Console to all Proxmox VE hosts. This is not recommended as it bypasses plugin logic and may leave residual configurations.
  5. Remove the SANsymphony storage class from Proxmox VE
    1. Once all disks are removed, delete the storage class using one of the following methods:
      1. Using Proxmox storage manage:
          Copy
          Command
          pvesm remove <storage_class_name>
      2. Using the plugin (interactive):
          Copy
          Command
          ssy-plugin remove
      3. Verify removal (Check that the storage class no longer appears in Proxmox VE storage listings.)
          Copy
          Command
          pvesm status | grep -i <storage_class_name>
