1-) Do I really need to unencapsulate boot disk (using vxunroot, changing /etc/vfstab to c#t#d# format and going to single mode), or just dissassociating the mirror or plex will be enough?
-- Unencapsulation needs to be done, upgrade_start script will do that, this would be safe to do & if you disassociate mirror, you will have one safe copy for backout...
2-) Do I need to uninstall the old storage foundation before install the new version?
-- NO, upgrade will work directly from 4.1MP2 - 5.1
3-) According to the phased upgrade steps from 5.1 install guide, we need to execute installsf script for starting upgrade. But will it upgrade everything (VXFS and VCS) at the same time?
Or do I need to execute the same procedure twice? one to upgrade vxfs using installsf, and at the second time, I need to run installvcs, to upgrade VCS?
-- installsf will upgrade VCS & VXFS & VXVM (if you have), no need to run them separately
About MP, I have one doubt. I know I have to apply 4.1MP2, before upgrading to 5.1. Can I apply that MP in a live environment? What is the recommendation? Unencapsulating everything and going to single mode, or just stopping cluster using hastop -all?
-- Applying MP needs a reboot, it can be done in a live environment but it needs a reboot once finished since new upgraded modules needs to be loaded
-- To be safer side, it would be good to unencap & dissassociate the mirror as you will have a good copy to roll back in case of issues & yes, if this is a cluster setup, first thing would be to do "hastop -all" so that all applications are stopped so that you can proceed with unencap & diss of plexes.
Hope this helps
