3. Remove all Fluid Cache mappings from all volumes in the cluster (see Removing Volume Mappings).
Note that you do not have to remove non-Fluid Cache mappings.
4. In Enterprise Manager’s Storage view, right-click the Fluid Cache cluster and click Delete.
5. When prompted to confirm the deletion, click OK.
There may be a delay while the deletion is processed.
6. Shut down the Fluid Cache guest machines.
7. After deleting the cluster, remove the cluster’s static and dynamic iSER initiator targets:
NOTE: If you do not delete the old targets when removing or deleting clusters, the list of iSER
targets can gradually become cluttered with obsolete addresses. This adversely affects
performance and may eventually cause time out issues.
