Restore SSDs to storage drives for a node pool

You can disable L3 cache for SSDs on a node pool and restore those SSDs to storage drives.

About this task

Note Image

On HD400 node pools, SSDs are only used for L3 cache, which is turned on by default and cannot be turned off. All other node pools with SSDs for L3 cache can have their SSDs migrated back to storage drives.

Procedure

  1. Click File System > Storage Pools > SmartPools.
  2. In the Tiers & Node Pools area of the SmartPools tab, select View/Edit next to the target node pool.
    The View Node Pool Details dialog box appears, showing the current settings of the node pool.
  3. Click Edit.
    The Edit Node Pool Details dialog box appears.
  4. Clear the Enable L3 cache check box.
    The setting is grayed out for node pools without SSDs, or for which the setting cannot be changed.
  5. Click Save Changes.
    The Confirm Change to L3 Cache Setting message box appears.
  6. Click Continue.
    The migration process to disable L3 cache begins and can take awhile, depending on the number and size of the SSDs in the node pool. When the migration process is complete, the View Node Pool Details dialog box appears.
  7. Click Close.
