Upgrading the disk layout versions

12Verify the syntax of the /etc/VRTSvcs/conf/config/main.cf file by running the following commands on system01:

#cd /etc/VRTSvcs/conf/config

#/opt/VRTS/bin/hacf -verify .

13Run the following command on all the nodes to start VCS.

#/opt/VRTS/bin/hastart

14Configure SFCFS on all the nodes. See “Using the log files”.

Note: VCS configuration files are not changed during this configuration.

15Upgrade file systems to proper disk layout version as mentioned in “Upgrading the disk layout versions” on page 50.

16Verify that all the file systems are working properly and data is intact. See cfsmount(1M).

Upgrading the disk layout versions

SFCFS 5.0 supports disk layouts Versions 4, 5, 6 and 7 for locally mounted file systems and disk layouts Versions 6 and 7 for cluster mounted file systems. If you have cluster mounted file systems with disk layout versions lower than 6, then after upgrading to SFCFS 5.0, perform the following additional steps to prepare the file system for being mounted on all nodes of the cluster:

1Select one of the nodes of the cluster and mount the file system locally on this node. For example, mount it without the -oclusteroption. Enter,

#mount -F vxfs block_device_path /mnt1

2Current disk layout version on a file system can be found using

#fstyp -v char_device_path grep version \

awk '{print $2}'

3On the node selected in step 1, incrementally upgrade the disk layout of this file system to layout Version 6 or layout Version 7. For example, if you had a cluster mounted file system of disk layout Version 4 while running with SFCFS 3.5 on HP-UX 11i Version 1, after upgrading to SFCFS 5.0, you would need to upgrade the disk layout to version 6 or version 7 incrementally as follows:

#vxupgrade -n 5 /mnt1

#vxupgrade -n 6 /mnt1

#vxupgrade -n 7 /mnt1
