In-Depth Information
5. If any third-party software is installed on the system, check with the
software manufacturer to verify that the software will run on Solaris 9.
It might be necessary to purchase new versions of third-party software.
6. Back up the existing system completely. If the upgrade fails, it might be
necessary to restore to the existing system until the reasons for failure
can be determined and resolved.
7. Collect any configuration information that might be needed during the
upgrade, such as hostname, network interface, IP address, subnet mask,
and domain name. You can avoid the need to respond to prompts dur-
ing installation by preconfiguring system configuration information,
which is discussed later in this chapter.
8. Set up a backup medium for use during the upgrade. In the event that
disk space needs to be reallocated, file systems will need to be copied
to a backup medium, and then reloaded after the space on the system
disk(s) has been adjusted. You can use local devices, such as an unused
system disk, a tape, or a disk, along with remote files systems, for back-
up media.
9. If you're using the Solaris 9 distribution CD/DVD, insert the
CD/DVD in the system CD-ROM/DVD drive. If installation is to be
performed over the network, set up an install server and possibly a
boot server.
10. Reboot the system.
During the Upgrade
If the current layout of the system disks does not provide enough space for
the upgrade, the Solaris Interactive Installation (SunInstall) will use the auto-
layout feature to reallocate disk space as required. If the auto-layout fails or
a different layout is desired, the disk layout must be manually specified.
If the system configuration information was not preconfigured, you need to
provide the appropriate information when prompted.
After the Upgrade
Merging the existing system configuration with the Solaris 9 operating sys-
tem might not have been completely successful, and it might be necessary to
perform some manual cleanup. Check the /a/var/sadm/system/data/
upgrade_clean file to determine whether any configuration problems need
to be reviewed and possibly modified before the system can be rebooted.
After resolving any cleanup issues, reboot the system.
