Lvlnboot output

[George C. Abraham_2]

Hi admins,

in one of my HP systems (rp7100) the output of lvlnboot -v comes like this

# lvlnboot -v
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/dsk/c0t6d0 (1/0/0/3/0.6.0) -- Boot Disk
/dev/dsk/c3t6d0 (1/0/1/0/0/1/1.6.0) -- Boot Disk
Boot: lvol1 on: /dev/dsk/c0t6d0
/dev/dsk/c3t6d0
Root: lvol3 on: /dev/dsk/c0t6d0
/dev/dsk/c3t6d0
Swap: lvol2 on: /dev/dsk/c0t6d0
/dev/dsk/c3t6d0
Dump: lvol2 on: /dev/dsk/c0t6d0, 0

Current path "/dev/dsk/c10t0d1" is an alternate link, skip.
Current path "/dev/dsk/c8t0d2" is an alternate link, skip.
Current path "/dev/dsk/c10t0d3" is an alternate link, skip.
Current path "/dev/dsk/c8t0d4" is an alternate link, skip.
Current path "/dev/dsk/c10t0d5" is an alternate link, skip.
Current path "/dev/dsk/c8t0d6" is an alternate link, skip.
Current path "/dev/dsk/c10t0d7" is an alternate link, skip.
Current path "/dev/dsk/c8t1d0" is an alternate link, skip.


I have mirrored only the internal disks. but dont get how the other alternate links show up..Please explain.. point will be given.

Thanks

Hi,

If you do not specify a volumegroup all the volumegroups known will be queried. I think your server has other volume groups configured with alternate paths. And lvlnboot complains about them If you specify lvlnboot -v /dev/vg00 the output must be normal.

Gideon has hit the proverbial nail on the head:

root# lvlnboot -v vg00
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/dsk/c1t6d0 (0/0/2/0.6.0) -- Boot Disk
/dev/dsk/c2t6d0 (0/0/2/1.6.0) -- Boot Disk
PV Name: lvol1 on: /dev/dsk/c1t6d0
/dev/dsk/c2t6d0
Root: lvol3 on: /dev/dsk/c1t6d0

Swap: lvol2 on: /dev/dsk/c1t6d0
/dev/dsk/c2t6d0
Dump: lvol2 on: /dev/dsk/c1t6d0, 0

Hi George,

You can disregard the alt link msgs at the bottom. Happens because all disk are queried for LIF records & alt links are ignored.

BUT - you have a problem with your vg00 mirroring - it's incomplete. You should have duplicate entries for root/boot/swap like the following:

root@host1:/home/user1:lvlnboot -v
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/dsk/c0t6d0 (1/0/0/3/0.6.0) -- Boot Disk
/dev/dsk/c3t6d0 (1/0/1/0/0/1/1.6.0) -- Boot Disk
Boot: lvol1 on: /dev/dsk/c0t6d0
/dev/dsk/c3t6d0
Root: lvol3 on: /dev/dsk/c0t6d0
/dev/dsk/c3t6d0
Swap: lvol2 on: /dev/dsk/c0t6d0
/dev/dsk/c3t6d0
Dump: lvol2 on: /dev/dsk/c0t6d0, 0

Current path "/dev/dsk/c5t7d6" is an alternate link, skip.
Current path "/dev/dsk/c5t7d7" is an alternate link, skip.
Current path "/dev/dsk/c5t10d0" is an alternate link, skip.
Current path "/dev/dsk/c4t10d1" is an alternate link, skip.
Current path "/dev/dsk/c4t9d7" is an alternate link, skip.

I suspect you missed a step in the vg00 mirror procedure. You'll probably have to start over from the beginning & make sure you start with pvcreate -B to set aside the LIF space.
You don't need to have a mirror for the dump.

HTH,
Jeff

Wait a minute - NEVER MIND!

The dang formatting on the forum.....
I misread the post.
I sure wish it wouldn't do that.
Really makes output of commands like this misleading.

Sorry,
Jeff

Jeff you almost gave me a shock..

Happy holidays
