HP LOGICAL VOLUME

[Carme Torca]

Hi,

I have one itanium with two disks connected, but when I do an
#ioscan -fnuCdisk, it shows me

disk 1 0/2/1/0/4/0.0.0 sdisk CLAIMED DEVICE HP LOGICAL VOLUME

/dev/dsk/c4t0d0 /dev/rdsk/c4t0d0
/dev/dsk/c4t0d0s1 /dev/rdsk/c4t0d0s1
/dev/dsk/c4t0d0s2 /dev/rdsk/c4t0d0s2
/dev/dsk/c4t0d0s3 /dev/rdsk/c4t0d0s3

What is it?
Thanks!
Carmen.

And how can I make a mirror with this?, if its only one LOGICAL VOLUME with 2 disk?

Thanks!

Hi,

Hi,

No the system has two disk, but it doesn't shows:
CLAIMED DEVICE HP 36.4GST336753LC

it shows:
CLAIMED DEVICE HP LOGICAL VOLUME

[Enrico P. · Accepted solution]

In attach the LVM mirror procedure for Itanium.

I don' t understand ...

You have two disks and one LV that "split" in this two disk?

I'm sorry
At the machine are two disk, but when I do an ioscan this shows me HP LOGICAL VOLUME, and there are two solutions (I think):

1) One of the disk are bad connect
2) HP LOGICAL VOLUME means the 2 disks together ¿?

But, if HP LOGICAL VOLUME means only one disk, then I maybe have one disk wrong.

What do you think?

Thanks!
Carmen.

I dont' know why the "HP LOGICAL VOLUME " output but the

/dev/dsk/c4t0d0

is the special file for the disk

and the s1 s2 s3 is for the partition in the same disk then for me you see one disk.

The LVM mirror on 11.23 is different from LVM mirror on 11.22. Which one do you have?
