To move a host to a new host group/cluster or to decommission a host, the plugin also offers a feature to deconfigure a host on the FlashArray.
To deconfigure a host, click on the host or a cluster object that owns the desired host, in the vCenter inventory, followed by the Configure tab, then Everpure > Host Connections.
Select the FlashArray and the host object you want to remove and click Disconnect Host.

This will surface a screen asking for confirmation of the removal.

The plugin will execute the following steps:
-
Destroy the host object on the FlashArray
Note:
Note that this process will remove all storage on that array from that host. If the host is using that array to boot from (like Boot From SAN), sudden removal will crash the host. Please use caution when disconnecting hosts via the plugin.
In order to remove a host, the plugin requires the host to be in maintenance mode. This requirement is a precaution to prevent accidental removal of storage for running virtual machines. This requirement may be adjusted or lifted in the future as more specific workflows are developed.
If the host is not in maintenance mode, the plugin will not allow the procedure to go forward.
Note:Deconfiguring a host does not remove the iSCSI targets from the ESXi host itself for the specified FlashArray. Only the array-side configuration is removed. The removal of iSCSI target information will be included in a future release.
