PowerStore: Uninstalling the ESXi Host Import Plug-in After Import Operations

This article explains how to uninstall the PowerStore VMware host plug-in after a migration operation.

After finishing a PowerStore Import migration from the external storage array, it is possible to uninstall the PowerStore VMware host plug-in used on the host. This process causes host downtime and requires reconfiguration. The ESXi host should be rebooted after uninstalling the plug-in, and Virtual Machine File System (VMFS) volumes must have a new signature.

Uninstalling the Import host agent is disruptive and requires VMFS datastore re-signature. Therefore, removing the installation is not necessary and not recommended, as it requires host downtime and reconfiguration.

1. On the ESXi Import host, remove the IMPORT SATP claim rules for all volumes that were imported

esxcli import equalRule remove

2. Uninstall the VMware host plug-in. 

esxcli software vib remove -n dellemc-import-hostagent-provider -n dellemc-import-satp

3. Reboot the ESXi host.
4. Write a new signature on the VMFS datastore on the imported volume. See Broadcom article Resignature a VMFS Datastore 
5. Re-register your VMs with the datastore after the resignature operation is completed.
