setboot error during root disk mirroring

rianui — Fri, 16 Jan 2009 09:07:04 GMT

Dear Experts,

I have a HP rp7640 which I have installed UX 11.23. After installation I went through the steps to mirror the disks but when I typed the setboot -a command, I get the error:

setboot: cannot set alteranate bootpath

Here is what I did...I pasted everything including an error I got during vgextend:

# pvcreate –f -B /dev/rdsk/c4t6d0

Hi,

Can you post the output of "lvlnboot -v"?

Also did you add an entry for the new disk in /stand/bootconf file?

Hi Delcho,

1) Here is the output of lvlnboot -v:

[root@casper1 - /root ] # lvlnboot -v
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/dsk/c0t6d0s2 (0/0/0/3/0.6.0) -- Boot Disk
/dev/dsk/c4t6d0 (1/0/0/3/0.6.0) -- Boot Disk
Boot: lvol1 on: /dev/dsk/c0t6d0s2
/dev/dsk/c4t6d0
Root: lvol3 on: /dev/dsk/c0t6d0s2
/dev/dsk/c4t6d0
Swap: lvol2 on: /dev/dsk/c0t6d0s2
/dev/dsk/c4t6d0
Dump: lvol2 on: /dev/dsk/c0t6d0s2, 0

2) No I did not add any entry in /stand/bootconf file.
All that's pasted above is what I did after the OS installation.

Thanks and regards

Rianui

Hi,

/dev/dsk/c0t6d0s2 (0/0/0/3/0.6.0) -- Boot Disk
/dev/dsk/c4t6d0 (1/0/0/3/0.6.0) -- Boot Disk

uhhh, you are trying to mirror an itanium system with the steps of an RISC system!!!!

Have a look at the appendix of this doc (page 50).

Hi, there is a whole procedure for mirroring root disk. You should follow it. In short words :

1. prepare partiton file:

3
EFI 500MB
HPUX 100%
HPSP 400MB

2.create device files for new disk (use insf!!!!)
3.verify partiton table of the new disk (use idisk!!!)
4.Populate /efi/hpux in the new EFI partition in the new disk! (use mkboot!!!)
5.Change auto file (booting from disks must be without quorum...use "boot vmunix -lq" and efi_cp to ..rdisk/newdisk_s1)
6.Check that "boot vmunix -lq" option is set to all boot disks (use efi_cp!!!)
7.Create a pv (use pvcreate with ..rdsk/newdisk_s2!!!)
8.Extend vg00 (use ..dsk/newdisk_s2)
9.Mirror all lvs from vg00 (use lvextend)
10.Add new disk to /stand/bootconf
11.Check BDRA with lvlnboot command
12.Set primary and alternate boot path (use setboot with HW paths!)
13 .Check with setboot!
If You need more iformation I suggest to read this document:
