Symptoms

After completing PowerStore Import migration from the external storage array, it is possible to uninstall the PowerStore plug-in that was used on the Host. The article describes how to perform the uninstall.

Cause

Caution: Removing the installation is not necessary, and not recommended since the process requires host downtime and reconfiguration.


If the caution above is understood and the PowerStore import plug-in for Linux must be uninstalled, follow the steps below.

Resolution

 

1. Unmount all previously imported PowerStore volumes from the Linux Host.

 


2. Uninstall the Linux Host plug-in: 

./minstall -e

 

 

3. Unmap the Linux host from the PowerStore array; PowerStore Manager > Compute > Hosts & Host Groups.

 

 

4. On the Linux host, rescan iSCSI devices: 

iscsiadm -m session --rescan

 

 

5. Remount the volumes on the Linux host using the PowerStore Device Mapper worldwide name id (WWNID):

Example:

mount /dev/mapper/364842a249255967294824591aa6e1dac /mnt/364842a249255967294824591aa6e1dac

 

 

6. Edit the /etc/fstab file with the WWNIDs to make persistent after host reboots: 

/dev/mapper/364842a249255967294824591aa6e1dac /mnt/364842a249255967294824591aa6e1dac ext3 acl,user_xattr,nofail 0 0
