vxrootmir doesn't mirror rootvol

Stefano_65 — Fri, 28 Jan 2005 10:30:29 GMT

Hi everybody,
I'm in a big trouble:
I'm trying to mirror rootdg on itanium platform, using standard procedure:

. paritionfile
. idisk
. insf
. mkboot
. vxrootmir -v cxtydzs2

every vol is ok, except rootvol

I tryed to remove mirror, remove disk and redo the procedure, with teh sam result.

I think the procedure is good, in the second server I'm installing everything goes fine.

Thanx for your help.

I forget that info:

The first time I mirrored rootdg was ok.
Than, I needed to remove mirror (vxassist remove mirror), and than remirror on the same disk, and the problem appears.

Hi Stefano,

although I think I'm of little help to your problem since I neither run any 11.23 OS,
and all the VxVM stuff we do is under Solaris, your final statement that the disk got skipped rose my suspicion.

At least under Solaris VxVM there are a couple of config files that leave you exclude certain disks, controllers etc.
Although the VxVM config file targets may differ between Solaris and HP-UX,
do you have any of these files (maybe do a find for the basename from /)?

/etc/vx/cntrls.exclude

/etc/vx/disks.exclude

/etc/vx/enclr.exclude

If so look if your particular disk, controler, enclosure is listed in there.

Yet another often issue is that the disk doesn't have a VxVM conforming partition/slice layout.
Have you checked this?
Sorry I don't know anything about partitions on HP-UX (we only use LVM on this platform),
and under Solaris you would look if the disks is labeled and look at the disk's VTOC.
But don't know how to do these checks on 11.23

Hi,

Could it be you need to remove and readd the private region on the disk ?
