mirroring vg00 system disk different on 11.23 than 11.11?

[Joe Profaizer]

I'm trying to add /dev/dsk/c2t0d0 to vg00 which already has c2t1d0 as it's only disk. Both are I'm using the following commands:
0. pvcreate -B /dev/rdsk/c2t2d0
1. mkboot /dev/rdsk/c2t2d0
2. mkboot -a "hpux -lq" /dev/rdsk/c2t2d0
3. for LVOL in `ls /dev/vg00/l*`
do
lvextend -m 1 $LVOL
done
4. lvlnboot -v <- Just to make sure it is all clean

Some of the errors I'm getting is:
# mkboot /dev/rdsk/c2t0d0
-W requires file system on device /dev/rdsk/c2t0d0

# mkboot -a "hpux (;0)/stand/vmunix" /dev/rdsk/c2t0d0
-a specified but no current boot area on /dev/rdsk/c2t0d0

Are there any steps I'm missing. This was a surefire way while on 11.11.

Both disks are HP 73.4GST373453LC

Thanks....
..Joe

As far as I've been told there is no difference in the proces. My complete reference on the subject.

pvcreate -B /dev/rdsk/c1t0d0 #use real disk

mkboot -l /dev/rdsk/c1t0d0
mkboot -a "hpux -lq (;0)/stand/vmunix" /dev/rdsk/c1t0d0 # use real disk


# mkboot -b /usr/sbin/diag/lif/updatediaglif -p ISL -p AUTO -p HPUX -p PAD -p LABEL /dev/rdsk/c?t?d?

If you are running 64-bit OS:

# mkboot -b /usr/sbin/diag/lif/updatediaglif2 -p ISL -p AUTO -p HPUX -p PAD -p LABEL /dev/rdsk/c?t?d?


vgextend /dev/vg00 /dev/dsk/c1t0d0 # same thing
lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/c1t0d0

# real disk. repeat for other lvols

lvlnboot -r /dev/vg00/lvol3 # root fs /
lvlnboot -s /dev/vg00/lvol2 #swap
lvlnboot -d /dev/vg00/lvol2 #swap/dump
lvlnboot -b /dev/vg00/lvol1
lvlnboot -R
lvlnboot -v
setboot
setboot -a 52.1.0 # second disk

YES, there is a different procedure on 11.23 than on 11.11.

Check out knowledge base article KBRC00014526

Hi,

procedure for doing mirror on HP-UX 11.23
Itanium is quite different because you have to
create partitions for EFI, HPUX and HPSP.
You can create this by idisk command. After that we use partitions 2 for LVM root disk.
In appendix there is my script for 11.23 itanium.

Hi Joe,

There is quite a bit.. You can't use any commands that would update the LIF as there is no LIF concept on Itaniums. Also, you would see sliced disks instead of partitioned ones.. For ex., c2t0d0 would be c2t0d0s1 for eFI partition and c2t0d0s2 for root disk paritition.

I just have to say...ty ty ty

I just got a rx2600 and have been beating my head against the wall.

I give these responses a 10 since the person asking the question did not.

Would someone post a revised procedure so I can update my bookmarks?

Hi Guys,

The procedure for Integrity (!) servers is totally different.
If you run 11.23 or 11.31 on a PA-RISC the procedure is very similar to 11.11.

Reference:

http://docs.hp.com/en/B2355-90950/ch06s02.html#cchgjafa

"Mirroring a Boot Disk with LVM on HP-UX 11i for HP Integrity Servers"

[Torsten.]

Another resource is the Appendix A chapter "How to mirror the root volume (Integrity servers)" in this well-known document:


http://docs.hp.com/en/5991-1236/When_Good_Disks_Go_Bad.pdf

[Torsten.]

And finally, another (different!) procedure to mirror ** 11.31 ** boot disks.

The procedure is different for both (Integrity and 9000's), because of the different device files.

legacy:
/dev/dsk/cxtydzsn

new:
/dev/disk/diskx_pn
