b. Select the check box of the appliance to remove.
c. Click Remove.
The Removing the Appliance dialog box is displayed.
d. Click Remove.
The appliance is removed from the cluster and reset to its factory default settings. The appliance can be rediscovered and
deployed to a new or existing cluster after it is reset to factory default settings.
NOTE: The factory reset of the appliance can take up to four hours to complete.
Migrate storage objects from an appliance
Use appliance storage object migration to move storage resources to another appliance or multiple appliances in the cluster. This
feature is applicable if you want to evacuate space from an appliance, power off an appliance, or remove an appliance from a
cluster.
About this task
Volumes, volume groups, and vVols are eligible for migration. When you migrate a storage object, all associated snapshots and
thin clones are also migrated.
The following storage objects are not eligible for migration:
Table 8. Storage objects ineligible for migration
Ineligible object How to make the object eligible
File objects File objects cannot be migrated.
Volumes or volume groups in an
active import session
Wait for the import session to end.
Volumes, volume groups, or vVols in
an active internal migration
If the system is migrating objects from the appliance, wait for the migration to end. If
the system is migrating objects to the appliance, consider canceling the migration.
Offline volumes The volume is offline due to metadata inconsistencies. Contact your service provider to
bring it online.
vVols with bound snapshots Interrupt the VMware operation that created the bound snapshot or wait for the
process to complete.
vVol bound fast clones Power off the linked clones of the VM that the vVol belongs to.
You cannot migrate storage objects from an appliance that is out of space and has entered read-only mode. If an appliance is
out of space, you must add more storage capacity or delete storage objects until the appliance has at least 16 GB of free space.
To migrate storage objects to another appliance in the cluster:
Steps
1. Under Hardware, select the appliance from which you want to migrate storage objects.
2. Under More Actions, select Migrate.
3. Follow the prompts in the Migration wizard to migrate storage objects to another appliance.
NOTE: The maximum number of storage objects that you can select for a single migration action is 4000.
Results
The LUN ID of a volume changes automatically when a volume is migrated from one PowerStore appliance to another appliance
in the same cluster.
Follow these guidelines when migrating a boot volume:
● Power off the connected host before migrating the boot volume. Then, change the LUN ID for the boot volume after the
migration is performed and power on the host.
● The recommend Host LUN ID for a boot LUN is 0.
● After migrating a boot from SAN volume, the LUN ID can be changed back to 0.
