How to get rid of GPFS ?

UNIX AIX

Hi

We are doing the migration of DMX3 disks to DMX4 disks using migratepv. We are not using GPFS but we have gpfs disks present in the server. Can anyone advise how to get rid of GPFS in both the servers cbspsrdb01 and cbspsrdb02. I will do migratepv for the other disks present in the servers but im worried about the gpfs disks.

The below are the outputs from my servers :

Hi

Thanks for your reply :slight_smile:

I got the below link from IBM and this link contains the procedure to remove all traces of GPFS.
