PowerPath Administration on Solaris

7.Run the sol9_liveup.sh script and then activate the inactive boot environment:

a.Mount the root of the inactive boot environment to a directory such as /mnt.

b.Run the script sol9_liveup.sh. Enter:

cd /install_dir/EMCpower/scripts

./sol9_liveup.sh /mnt

where install_dir is the base install location of the EMCpower package. For example, if the base install directory is opt, enter:

cd /opt/EMCpower/scripts

./sol9_liveup.sh /mnt

c.Continue with the procedure documented in the Solaris 9 Installation Guide.

Troubleshooting

If Solaris Live Upgrade replaces the sd.conf file with a default sd.conf, the new boot image may not work. In this case, replace the default sd.conf with either the file Solaris Live Upgrade automatically saved in /kernel/drv/sd.conf.~version or the file you saved before starting the upgrade procedure. (See step 3, above.)

If you fail to run sol9_liveup.sh before activating Solaris 9, the new boot image will not work. In this case:

1.Boot from the older Solaris boot area.

2.Mount the Solaris 9 boot area.

3.Run sol9_liveup.sh in the Solaris 9 boot area.

4.Boot Solaris 9.
