To perform the upgrade

1. Log in as superuser.
2. Insert the appropriate media disc into your system's DVD-ROM drive.
3. If volume management software is running on your system, the software disc automatically mounts as /cdrom.

   If volume management software is not available to mount the disc, you must mount it manually, enter:

   # mount -F hsfs -o ro /dev/dsk/c0t6d0s2 /cdrom

   where c#t#d# is the location of the CD drive.

4. Change to the top-level directory on the disc:

   # cd /cdrom

5. Verify there are no VxFS file systems mounted on the nodes being upgraded:

   # mount -p | grep vxfs

   If any VxFS file systems are mounted, offline the group on each node of the cluster:

   # hagrp -offline group -sys system01
   # hagrp -offline group -sys system02
   # hagrp -offline group -sys system03
   # hagrp -offline group -sys system04

   where group is the VCS service group that has the CVMVolDg and CFSMount resource.

   If VxFS are not managed by VCS then unmount them manually:

   # umount mount_point

   Repeat this step for each SFCFSHA service group.

6. Start the upgrade from any node in the cluster. Enter the following command, and then press y to upgrade the cluster configuration.

   # ./installsfcfsha -upgrade

7. At the prompt, specify whether you accept the terms of the End User License Agreement (EULA).

   Do you agree with the terms of the End User License Agreement
   as specified in the storage_foundation_cluster_file_system_ha/EULA/
   en/EULA_CFSHA_Ux_6.0.pdf file present on media? [y,n,q,?] y

8. The installer discovers if any of the systems that you are upgrading have mirrored and encapsulated boot disks. For each system that has a mirrored boot disk, you have the option to create a backup of the system's boot disk group before the upgrade proceeds. If you want to split the boot disk group to create a backup, answer y.
9. The installer then prompts you to name the backup boot disk group. Enter the name for it or press Enter to accept the default.
10. If you are prompted to start the split operation. Press y to continue.

    Note:

    The split operation can take some time to complete.

11. You are prompted to enter the system names (in the following example, "host1" and "host2") on which the software is to be upgraded. Enter the system name or names and then press Return.

    Enter the system names separated by spaces on which to 
    install SFCFSHA: host1 host2

12. During the initial system check, the installer verifies that communication between systems has been set up.

    If the installer hangs or asks for a login password, stop the installer and set up ssh or rsh. Then run the installer again.

    See About configuring secure shell or remote shell communication modes before installing products.

13. After the system checks complete, the installer displays a list of the packages that will be upgraded. Press Enter to continue with the upgrade.
14. Output shows information that SFCFSHA must be stopped on a running system. Enter y to continue.
15. Press Return to begin removing the previous packages and installing the new.
16. Press Return again for summary information about logs and reboots.

    Do not remove the log files until the Veritas products are working properly on your system. Technical Support will need these log files for debugging purposes.

17. Update the configuration.
18. Only perform this step if you have split the mirrored root disk to back it up. After a successful reboot, verify the upgrade and re-join the backup disk group. If the upgrade fails, revert to the backup disk group.

    See Re-joining the backup boot disk group into the current disk group.

    See Reverting to the backup boot disk group after an unsuccessful upgrade.
