PowerPath Administration on Solaris
Upgrading Solaris
PowerPath 4.0 supports Solaris Live Upgrade, which lets you
upgrade the operating system without uninstalling PowerPath.
Solaris Live Upgrade is supported for upgrades to Solaris 9 only. If you are
upgrading to an earlier version of Solaris, you must uninstall PowerPath
before you upgrade the OS and then reinstall PowerPath after the upgrade.
Upgrading to Solaris 9 with Solaris Live Upgrade
The PowerPath 4.0 package includes a script, sol9_liveup.sh,
located in the
scripts subdirectory of the PowerPath 4.0 installation
directory (for example,
/opt/EMCpower/scripts). You must run this
script before you activate Solaris 9.
Solaris Live Upgrade does not work when booting off emcpower devices.
To upgrade to Solaris 9:
1. Ensure that the HBA driver is supported with Solaris 9.
Otherwise, Solaris Live Upgrade will not work.
2. Install PowerPath 4.0 on the host.
3. Optionally, save the
sd.conf file.
Solaris Live Upgrade may replace
sd.conf with a default sd.conf
file, causing devices to become inaccessible. If those devices are system
critical devices, the new boot image will not work.
Solaris Live Upgrade saves a copy of the
sd.conf file in
/kernel/drv/sd.conf.~version (where version is the Solaris version
from which you are upgrading; for example, if you are upgrading from
Solaris 8, the file name is
sd.conf.~8.) Nevertheless, you might want
to save
sd.conf before you start the upgrade.
4. Install Solaris Live Upgrade on the host.
5. Create an inactive boot environment. Follow the instructions in
the Solaris 9 Installation Guide.
6. Upgrade the inactive boot environment. Follow the instructions
in the Solaris 9 Installation Guide.
