NFS fix for all vxfs volumes

Applying the NFS fix on all vxfs volumes

----------------------------------------

Before starting the activity make sure application team shutdowns all the application services so that we can umount the desired VXfs volumes.

1. Login as superuser.

2. umount all the volumes in disk groups.

3. Stop all the volumes for all the dg's.

# vxvol -g <dg-name>  stopall

eg,  vxvol -g cipcissdb025bkpdg stopall - will stop all volumes on the dg xxyydb025bkpdg

4. verify that the above volumes where stopped successfully

# vxprint -g <dg_name> | grep ^v

- KSTATE should show as DISABLED.

5. To change minor numbers of the volumes in all diskgroup's to less than 255 - execute the following command for every DG.Note - set minor number different for every DG but it should be less than 255.

# vxdg -g <dg_name> reminor 100

6. verify the minor numbers are changed successfully for all the volumes to less than 255

7. start all the volumes in dg cihcissdb027bkpdb

# vxvol -g <dg_name> startall

8. verify the all the volumes in all dg's started successfully.

# vxprint -g testdg1 | grep ^v

9. Mount all the volumes in dg's - mount -a or mount every volume one by one.

10. verify all the mount points as before umouting the volumes exists
