Secure disk wiping
This uses the purge utility built into the format command. Boot the system off a cd to single user mode with
boot cdrom -s
format and select the analyse menu, select purge and
slice 2 for the whole disk. The program warns you that it will take a considerable amount of time, it's not kidding. This could take several hours or more depending on the disk size.
See Sun Tech FAQ.

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 # ./install_cluster
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
