NOTE:
When the appliance removal process is running, do not run commands that can change the state of the cluster,
such as adding external hosts or changing CHAP configurations.
Steps
1. Under Hardware, select Appliances, and identify the IP address of the appliance with the Service Tag identified in
Prerequisites.
2. Under Settings, select Network IPs, identify the Host Node IPs of the appliance.
3. If the appliance to be removed has VMFS volumes with internal host mappings, migrate the VMFS volumes to another
appliance:
a. Identify the related compute VMs and VMFS volumes on the appliance.
b. Ensure that internal host mappings are defined between the VMFS volumes and the hosts on the destination appliance.
If these internal host mappings do not exist, create the host mappings before continuing.
c. Manually migrate the VMFS volumes from to the destination appliance using PowerStore Manager.
d. vMotion the related compute VMs to the destination appliance.
NOTE:
Do not vMotion the vCLS VMs.
e. Unmap the VMFS volumes from the appliance to be removed using the PowerCLI.
4. Migrate the virtual volumes for vCLS VMs on the appliance to another appliance in the cluster using PowerStore Manager.
a. Under Storage, select Storage Containers, select the storage container that contains the virtual volumes for the vCLS
VMs, and select Virtual Volumes.
b. Select Show/Hide Columns and select the Appliance check box to display the appliances on which the virtual volumes
are located.
c. Identify the virtual volumes for the vCLS VMs that must be migrated.
d. Select a virtual volume to migrate and select Migrate.
NOTE:
You can only migrate one virtual volume at a time.
e. Select the appliance to which to migrate the virtual volume and click Next.
f. Repeat the previous steps for each virtual volume in the storage container.
5. Disable support notifications on the PowerStore cluster as described in
6. Run the svc_appliance_provisioning script to disable resource balancing and prevent objects from being
automatically created or placed on the appliance that you want to remove.
a. Open an SSH client, and connect to the management IP address of the appliance to remove.
NOTE:
External SSH management access must be enabled on the appliance.
b. Type the username and password of the service account to log in to the appliance.
c. Run the following command to display the names of the appliances in the cluster:
svc_appliance_provisioning list
d. Run the following command, where appliance_name is the name of the appliance that you want to remove:
svc_appliance_provisioning disable appliance_name
e. Run the following command to ensure that the provision status of the appliance is disabled:
svc_appliance_provisioning list
7. Identify the primary and secondary nodes of the appliance in PowerStore Manager.
a. Under Hardware, select Appliances, and select the appliance to remove.
b. On the Appliance Details page, select the Components card and select the Internal View tab.
The node with the text (primary) is the primary node of the appliance, and the node without the text (primary) is the
secondary node. The names of the nodes are Node A and Node B.
c. Under Settings, select Network IPs and select the Management tab.
d. Record the Host Node IP addresses of Node A and Node B on the appliance.
