10. Contact Dell Support for instructions on the removal of claim rules. This must be done before you

can redeploy Fluid Cache on the same guest machines. An alternative to removing claim rules is to

completely format and reinstall the hosts (not just an upgrade install) of ESXi.

11. 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.

a. On the Configuration tab of the VMware client, choose Storage Adapters.

b. Right-click the first VMHBA below Mellanox iSCSI over RDMA (iSER) Adapters and click

Properties.

c. In the iSCSI Initiator Properties window, select the Dynamic Discovery tab.

d. Choose the first IP address listed under iSCSI Server Location, then click Remove.

e. Repeat this process until the list is empty except for addresses used by non-Fluid Cache iSCSI

servers.

f. In the iSCSI Initiator Properties window, select the Static Discovery tab.

g. Choose the first IP address listed under iSCSI Server Location, then click Remove.

h. Repeat this process until the list is empty except for addresses used by non-Fluid Cache iSCSI

servers.

i. Close the Properties window, and rescan when prompted to do so.

Recreating a Fluid Cache Cluster

Although it is not part of standard operations or maintenance, in some instances you may want to

recreate a Fluid Cache cluster.

1. Make sure that no cached LUNs on the servers are in use.

NOTE: All cached data on a server is lost when you perform the following procedure. Flush this

data before proceeding.

2. Reinstall the Fluid Cache VSA. See Installing the Virtual Storage Appliance and the procedures that

follow for mapping hardware and configuring a server.

3. Create and configure a new cluster. See Configuring and Managing Fluid Cache Clusters.

Upgrading Fluid Cache Cluster

There is no direct method to upgrade Fluid Cache cluster to new releases.

To deploy a new release of Fluid Cache, perform the following steps:

1. Remove the Fluid Cache cluster. See Deleting or Removing a Fluid Cache Cluster

2. Turn off and delete all the VSAs.

3. Create and configure a new cluster. See Configuring and Managing Fluid Cache Clusters
