To Prepare the Domain for the Upgrade
1. Log in to the domain as superuser and backup the domain if you have not already
done so.
Using ufsdump(1M), backup all operating-system file systems.
2. Comment out all of the file systems in the /etc/vfstab file except root (/), /usr,
/export,/var, /opt, /proc, /dev/fd, /tmp, and swap if you have not already
done so.
3. Comment out all swap partitions that are not on the same controller as the root
disk.
During an upgrade, the suninstall utility attempts to adds all of the swap devices
listed in the /etc/vfstab file. If the suninstall utility cannot access a swap
device, it reports the failure and exits.
4. If any metadevices exist (for example, disk, network, mirrored, striped, or
concatenated) for Alternate Pathing, Solstice DiskSuite, Sun™ Enterprise™
Volume Manager, or Veritas, refer to the installation instructions for those
products and perform the appropriate steps to remove the metadevices.
This step is necessary because the suninstall utility cannot handle metadevices.
For more information about these products, refer to their respective user's guides.
Caution – Make certain that all metadevices are removed. If any are not, the
upgrade will fail.
5. If you removed metadevices, reboot the domain to ensure that all of the active
metadevices are removed.
domain_name# init 6
6. If you rebooted the domain in the prior step, and the reboot was successful, log in
to the domain as superuser.
7. If you are upgrading from Solaris 2.5.1, remove the SUNWxntp packages by using
the pkgrm(1M) command.
domain_name# pkgrm SUNWxntp
