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.
