Complete the following tasks before you perform the upgrade:
Review the Veritas Storage Foundation Release Notes for any late-breaking information on upgrading your system.
Review the Symantec Technical Support website for additional information:
Make sure that the administrator who performs the upgrade has root access and a good knowledge of the operating system's administration.
Make sure that all users are logged off and that all major user applications are properly shut down.
Make sure that you have created a valid backup.
Ensure that you have enough file system space to upgrade. Identify where you want to copy the depots, for example /packages/Veritas when the root file system has enough space or /var/tmp/packages if the /var file system has enough space.
Do not put the files on a file system that is inaccessible prior to running the upgrade script.
You can use a Veritas-supplied disc for the upgrade as long as modifications to the upgrade script are not required.
For any startup scripts in /sbin/rcS.d, comment out any application commands or processes that are known to hang if their file systems are not present.
Make sure that the current operating system supports version 6.0.1 of the product. If the operating system does not support it, plan for a staged upgrade.
Schedule sufficient outage time and downtime for the upgrade and any applications that use the Veritas products. Depending on the configuration, the outage can take several hours.
Any swap partitions not in rootdg must be commented out of /etc/fstab. If possible, swap partitions other than those on the root disk should be commented out of /etc/fstab and not mounted during the upgrade. Active swap partitions that are not in rootdg cause upgrade_start to fail.
Make sure the file systems are clean before upgrading.
Upgrade arrays (if required).
To reliably save information on a mirrored disk, shut down the system and physically remove the mirrored disk. Removing the disk in this manner offers a failback point.
