Doubts on VxVM,VCS Upgrade & root disk encapsulation
I have the below queries please
1) In order to stop VxVM to load at system boot time, we need to modify /etc/system file.
What entries are to be commented out ?
Is it only
(OR) also below entries are to be commented out ?
2) My current version of SFHA is 4.1. Once vxfen, gab & llt modules are unloaded to upgrade to 4.1MP2, should i again unload these modules
to further upgrade to 5.1SP1 and again to 5.1SP1RP4 (OR) 6.0 ? After each upgrade should i stop the
services in /etc/init.d and unload modules (OR) stopping services & unloading modules only once is
enough to further upgrade to other versions ?
My Plan is to upgrade from 4.1---> 4.1 MP2---> 5.1SP1--->5.1SP1RP4 (OR) 6.0
3) Before upgrading should i also stop & unload the below listed modules
24 12800a8 26920 268 1 vxdmp (VxVM 4.1z: DMP Driver)
25 7be00000 2115c8 269 1 vxio (VxVM 4.1z I/O driver)
27 12a4698 13f0 270 1 vxspec (VxVM 4.1z control/status driver)
213 7b2d7528 c40 272 1 vxportal (VxFS 4.1_REV-4.1B18_sol_GA_s10b)
214 7ae00000 1706a8 20 1 vxfs (VxFS 4.1_REV-4.1B18_sol_GA_s10b)
If yes, should i stop & unload after each upgrade (OR) doing it once is enough ?
4) Once the OS comes up with native disks (c#t#d#s#), In order to bring it under VxVM control we need to
encapsulate using vxdiskadm. My doubt is will rootdg, rootvol, plexes & subdisks be created
automatically? Need a little clarification regarding this please.
Response is highly appreciated as always,
Thank you very much.
