Prev	Performing a typical SFCFS upgrade using the installer	Next

Use these steps to perform a full upgrade from SFCFS 4.x or 5.x on HP-UX 11i v2 to SFCFS 5.1 SP1:

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

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

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.
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.

Take offline all VCS groups that contain CFSMount and CVMVolDg.

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

Unmount all the VxFS file system which is not under VCS control.
```
# umount /mount_point
```
Make sure that no processes are running which make use of mounted shared file system or shared volumes.
```
# fuser -cu mount-point
```
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
```

Freeze the VCS service groups. Run the following commands:

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

Stop VCS on all nodes:
```
# hastop -all -force
```
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.
On each node, edit the /etc/vxfenmode file to configure I/O fencing in disabled mode.
```
# cat /etc/vxfenmode 
vxfen_mode=disabled
```
On each node, change LLT_START=0 in the file /etc/rc.config.d/lltconf.

On each node, remove the following device files:

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

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

To upgrade from Veritas 5.0 releases on 11i v2, select the Base-VxFS-50, Base-VxVM-50 and Base-VxTools-50 bundles while using update-ux (1M) .
If any patches to the HP-UX 11i v3 are required, install all the prerequisite patches on all nodes before upgrading the Veritas products.
Install SFCFS 5.1 SP1.
```
# ./installer
```
From the installation menu, choose the G option for install and enter the number for VERITAS Storage Foundation Cluster File System.
Uncomment the VxFS mount point entries in the /etc/fstab file.
Reboot all the nodes.
```
# /usr/sbin/shutdown -r now
```
Check for hastatus - summ.

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

Set the clusterwide attribute "UseFence" to use SCSI3. Add the following line to the /etc/VRTSvcs/conf/config/main.cf file:
```
UseFence=SCSI3
```
Start the VCS engine on each system:
```
# hastart
```
