Question one:
I have received three replies with two votes telling me that my rootvol's
mirrored is fine.
Also, they told me that I can break the mirror and remirror them again without
the problem.
The reason the sub-disk is different is because the rootvol was encapsulated.
Question two:
Yes, I need the use eeprom use-nvramrc?=true before mirroring the rootvol.
Thanks,

Here is the original question:
------------------------------------
To All Helpers:
We are running solaris 2.6 on E450 with Veritas Volume Manager v
3.0.2,REV=08.30.1999.15.56
For the rootvol, I have mirror created but I did not use vxrootmir command to do
it, I was using scripts to create the mirror volume individually.
vxassist -g rootdg mirror rootvol layout=nolog mirrordisk
Now I notice for the rootvol, the sub-disk for plex rootvol-01 is different from
plex rootvol-02.
I think the difference is the boot block. Am I right?
Question one: Can I re-run the vxrootmir again to mirror the entire boot disk
again so the boot disk will have true mirroring. In case of boot drive fails, I
will be able to boot from the mirrored drive.
Question two: Do I need to run the eeprom use-nvramrc?=true. The document
suggests to run it before doing the mirroring.
Any suggestions and comments are welcomed.
Thanks for the help in advance,
Zion
