To upgrade from SFCFSHA versions on HP-UX 11i v2:

1. Log in as superuser to one of the nodes, system01 for example, in the cluster.
2. Create a backup of the existing cluster configuration. Back up the main.cf and types.cf on all cluster nodes:

   # cp /etc/VRTSvcs/conf/config/main.cf \
   /etc/VRTSvcs/conf/config/main.cf.save
   # cp /etc/VRTSvcs/conf/config/types.cf \
   /etc/VRTSvcs/conf/config/types.cf.save

3. If you created local VxFS mount points on VxVM volumes, added them to the /etc/fstab file, and comment out the mount point entries in the /etc/fstab file.
4. Stop all applications that use VxFS or VxVM disk groups, whether local or CFS.

   If the applications are under VCS control:

   # hagrp -offline grp_name -any

   If the applications are not under VCS control:

   Use native application commands to stop the application.

5. Take offline all VCS groups that contain CFSMount and CVMVolDg.

   # hagrp -offline group -sys system01
   # hagrp -offline group -sys system02

6. Unmount all the VxFS file system which is not under VCS control.

   # umount /mount_point

7. Make sure that no processes are running which make use of mounted shared file system or shared volumes.

   # fuser -cu mount-point

8. Stop all VCS service groups.

   To view the current state of the service groups:

   # hagrp -state

   To stop each group:

   # hagrp -offline servicegroup -sys node_name

9. Freeze the VCS service groups. Run the following commands:

   # haconf -makerw
   # hagrp -freeze servicegroup -persistent
   # haconf -dump -makero

10. Stop VCS on all nodes:

    # hastop -all -force

11. If the cluster-wide attribute "UseFence" is set to SCSI3, then reset the value to NONE in the /etc/VRTSvcs/conf/config/main.cf file.
12. On each node, edit the /etc/vxfenmode file to configure I/O fencing in disabled mode.

    # cat /etc/vxfenmode 
    vxfen_mode=disabled

13. On each node, change LLT_START=0 in the file /etc/rc.config.d/lltconf.
14. On each node, remove the following device files:

    # rm -f /dev/llt
    # rm -f /dev/gab*
    # rm -f /dev/vxfen

15. Upgrade the operating system from HP-UX 11iv2 to HP-UX 11iv3.

    To upgrade from Veritas 5.0 releases on 11i v2, select the related bundles for the target operating system version while using update-ux (1M).

    • Base-VxVM-50, Base-VxTools-50, Base-VxFS-50 for 11.31.1103.

    • Base-VxFS-501, Base-VxTools-501, Base-VxVM-501 for 11.31.1109 or 11.31.1203.

16. If any patches to the HP-UX 11i v3 are required, install all the prerequisite patches on all nodes before upgrading the Veritas products.
17. Install SFCFSHA 6.0.1.

    # ./installer

    From the installation menu, choose the G option for install and enter the number for VERITAS Storage Foundation Cluster File System.

18. Uncomment the VxFS mount point entries in the /etc/fstab file.
19. Set the LLT_START attribute to 1 in the /etc/rc.config.d/lltconf file:

    LLT_START=1

20. Reboot all the nodes.

    # /usr/sbin/shutdown -r now

21. Check the status of the cluster.

    # hastatus -sum

22. Post Upgrade Tasks: Enable fencing.

    # hastop -all
    # cp /etc/vxfen.d/vxfenmode_scsi3_dmp /etc/vxfenmode
    # /sbin/init.d/vxfen stop
    # /sbin/init.d/vxfen start
    

23. Set the clusterwide attribute "UseFence" to use SCSI3. Add the following line to the /etc/VRTSvcs/conf/config/main.cf file:

    UseFence=SCSI3

24. Start the VCS engine on each system:

    # hastart
