mirroring disks.

[Guest_imported]

I'm new to HP-UX 10.x and could use some instruction on the proper way to mirror 4 disks (jamaica drives).....

Here's all the info I think will be needed:

disks ( btw, what the diff between /dev/dsk and /dev/rdsk)
c4t1d0 c4t3d0 c4t5d0 c4t9d0
c4t2d0 c4t4d0 c4t8d0

unused:
8/12.1.0
8/12.10.0
8/12.2.0
8/12.3.0
8/12.4.0
8/12.5.0
8/12.6.0
8/12.7.0
8/12.8.0
8/12.9.0

from: ls -l /dev/vg*
vg-d00
vg-d01
vg-d02
vg-d03
vg-d04
vg-d05
vg00
vgu00

/dev/dsk/ = block device files (read/write happens in block mode)
/dev/rdsk = raw device file (read/write works bit by bit)

Did you run pvcreate commnad on all this?
You have not mention which one is mirrored disk and which one is not. Looks like you have vg already created. Need more info. like which disk is belog to vg00 and so.

I'm lost here... what info do you need?

All that I know is that there is already 2 other sets of disks mirrored.

the listing of disks above are those that need to be mirrored.

Hi eltorito,
second disk is c?t?d0
This is simple process for one disk to mirror.

1. pvcreate -B /dev/rdsk/c?t?d0
2. vgextend /dev/vg00 /dev/dsk/c?t?d0
3. mkboot /dev/rdsk/c?t?d0
4. mkboot -a "hpux -lq" /dev/rdsk/c?t?d0
6. For x in 1 2 3 4 5 6 7 8 9
do
lvextend -m 1 /dev/vg00/lvol$x /dev/dsk/c?t?d0
done
7. lvlnboot -R

to check after boot
lvlnboot -v

Also you need extra software HP-UX mirror. it is not part of OS.

Here's /dev/dsk:
c0t0d0 c0t1d0 c0t3d0 c0t5d0 c1t0d0 c1t1d0 c1t3d0 c1t5d0 c2t2d0 c4t1d0 c4t3d0 c4t5d0
c4t9d0 c0t15d0 c0t2d0 c0t4d0 c0t6d0 c1t15d0 c1t2d0 c1t4d0 c1t6d0 c4t10d0 c4t2d0 c4t4d0
c4t8d0

According to SAM, everything is being use but the c4t*d*(They're already being mirrored to/from)
[ there are 8 new drives, the c4t*d*... basically using 4, and mirroring each to one of their own)

so shouldn't I have to create a new logical drive for 4 of the c4*? (sorry for my ignorance.. )
From the way it looks in same, there are logical drives for the others.
