Im going to install Patch Cluster (10_Recommended.zip) on Solaris 10 (8/07) SPARC. Current kernel: Generic_120011-14.
I did that once in a past but only on my own test-lab machine.
This time I was asked to do this, on production server M5000 with disk array Sun StorageTek 2540 attached.
What I already know is to make a backup of files:
...and restore them after all.
Also I will make UFSDUMP of each filesystems (except those on array).
Is there anything more I sould know/perform before patching ?
I have prepared a short guid what to do. Could you please, take a look and give me some advices:
1. # init S
# cp /kernel/dev/st.conf /kernel/dev/st.conf.backup
# cp /kernel/dev/sd.conf /kernel/dev/sd.conf.backup
3. # ./install_cluster (around 2h)
# cp /kernel/dev/st.conf.backup /kernel/dev/st.conf
# cp /kernel/dev/sd.conf.backup /kernel/dev/sd.conf
5. # init 6
