EMC 300-000-978 REV A03 User Manual

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.

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.
