Install patch Cluster
Patch needs to be done in Single user mode:
# init S
Copy device names to backup in case they are overwritten, and do install
# cp /kernel/drv/sd.conf /kernel/drv/sd.conf.pre_cluster_installation
# cp /kernel/drv/st.conf /kernel/drv/st.conf.pre_cluster_installation
# cd $PATCH_CLUSTER_DIRECTORY
Installation of patch failed. Return code 2.
Installation of patch failed. Return code 8.
Code 2 means patch already installed.
Code 8 means that the patch is for a package not present on the system.
Copy device descriptions back if needed (check files with diff) & reboot system
# mv /kernel/drv/sd.conf.pre_cluster_installation /kernel/drv/sd.conf
# mv /kernel/drv/st.conf.pre_cluster_installation /kernel/drv/st.conf
# shutdown -i6 -g0 -y
Use showrev & showrev -p to show version of Solaris and the patches installed.
