Sanity check on mirror 11.23 on a itanium

[Evergreenscott]

I was checking root mirroring some system at this new place I'm at this morning. I have some 11.23 boxes set to "hpux vmunix -lq" and others "boot vmunix -lq". So, I'm second guessing myself but I think the right answer is "boot vmunix -lq". So, my sanity check is .. is that right way?

see what happens when the memory starts to go....

the -lq says it is ok to activate the VG without quorum ( more than 1/2 devices ).

In this case beings you are mirrored to allow availability if a disk fails you would not have quorum 1 out of 2 is not more than 1/2, hence the disable. All boot VGs should have quorum disabled to avoid this issue.

Any difference in result of "model"?

For integrity servers it is

boot vmunix ...

for PA-RISC servers it is

hpux vmunix ...

If all servers are Integrities, it should be the same "boot vmunix -lq" on all.


BUT, for 11.31 the mkboot command is the same for both, Integrity and PA-Risc!

# mkboot -a "hpux" /dev/rdisk/disk2

Check the system details!

I know the the -lq part, it's the first part that is making doubt myself. Is it .. "boot vmunix" or "hpux vmunix" ?

if its pa-risc "hpux vmunix -lq", if it's and integrity system, that uses EFI, you should use
"boot vmunix -lq"

cool. so I'm still sane. LOL. Thanks for the replies!!!

I have always used.

mkboot -a "hpux -lq" /dev/rdsk/cxtxdx

lifcp /dev/rdsk/cxtxdx":AUTO -

to confirm

Then always.. boot from mirror to test.
