Step 1: Performing pre-upgrade tasks on the first half of the cluster

Perform the following pre-upgrade steps on the first half of the cluster.

To perform the pre-upgrade tasks on the first half of the cluster

Back up the following configuration files: main.cf, types.cf, CVMTypes.cf, CFSTypes.cf, SybaseTypes.cf, /etc/llttab, /etc/llthosts, /etc/gabtab, /etc/vxfentab, /etc/vxfendg, /etc/vxfenmode
For example:
```
# 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
# cp /etc/VRTSvcs/conf/config/SybaseTypes.cf \
 /etc/VRTSvcs/conf/config/SybaseTypes.cf.save
```
The installer verifies that recent backups of configuration files in the VxVM private region are saved in /etc/vx/cbr/bk.
If not, the following warning message is displayed: Warning: Backup /etc/vx/cbr/bk directory.
Stop all applications that are not configured under VCS but dependent on Sybase ASE CE or resources controlled by VCS. Use native application commands to stop the application.

Stop the applications configured under VCS. Take the Sybase database group offline.

# hagrp -offline sybase_group -sys sys1
# hagrp -offline sybase_group -sys sys2

Stop the Sybase Binaries service group (binmnt group).

# hagrp -offline binmnt -sys sys1

# hagrp -offline binmnt -sys sys2

If the Sybase database is managed by VCS, set the AutoStart value to 0 to prevent the service group from starting automatically when VCS starts:
```
# haconf -makerw
# hagrp -modify sybasece AutoStart 0
# haconf -dump -makero
```
Unmount the CFS file systems that are not managed by VCS.
- Make sure that no processes are running which make use of mounted shared file system. To verify that no processes use the CFS mount point:
```
# mount | grep vxfs | grep cluster
```
```
# fuser -cu /mount_point
```
- Unmount the CFS file system:
```
# umount /mount_point
```
Stop the parallel service groups and switch over failover service groups on each of the nodes in the first half of the cluster:
```
# hastop -local
```
Unmount the VxFS file systems that are not managed by VCS.
- Make sure that no processes are running which make use of mounted shared file system. To verify that no processes use the VxFS mount point:
```
# mount | grep vxfs
```
```
# fuser -cu /mount_point
```
- Unmount the VxFS file system:
```
# umount /mount_point
```
Verify that no VxVM volumes (other than VxVM boot volumes) remain open. Stop any open volumes that are not managed by VCS.
```
# vxvol -g diskgroup stopall
# vxprint -Aht -e v_open
```
If a cache area is online, you must take the cache area offline before upgrading the VxVM RPM. On the nodes in the first subcluster, use the following command to take the cache area offline:
```
# sfcache offline cachename
```
Stop all the ports as follows:
For 6.0 and later versions:
For RHEL 7, SLES 12, and supported RHEL distributions:
```
# systemctl stop vxfen
# systemctl stop gab 
# systemctl stop llt
```
For earlier versions of RHEL, SLES, and supported RHEL distributions:
```
# /opt/VRTSvcs/vxfen/bin/vxfen stop
# /etc/init.d/gab stop 
# /etc/init.d/llt stop
```
