Please help

Thanks in advance

This shows there are two disks in your root vg & one of them is not responding i.e. (dev/disk/disk9_p2)There could a disk failure. in rx6600 SAS disks are installed.
Just check for ioscan -fnC disk confirm that all the disks are showing claimed. you can map the path (/dev/dsk/cxtxdx) using ioscan -m dsf command. Incase of disk failure please call up HP for replacing the disk.

Regards.

Fortunately it looks like all your lvols in vg00 are mirrored. one half of the mirror is up and running [/dev/disk/disk14_p2] while the other half of the mirror is broken
[/dev/disk/disk9_p2.]

As Sunil suggests, you need to do and ioscan to see it HPUX can see the bad disk. If so you can do a diskinfo /dev/rdisk/disk9_p2 and look at its size to see if you can read it. (a size of 0 is not good)

How to fix it will depend on what is wrong. Best case (e.g. disk is powered down or disconnected) you can just do a vgsync to re-sync the mirrors after you fix the problem. If you actually need to replace the disk, the steps are a little more involved. But again, because the lvols are mirrored, you can fix this without losing any data.

Hi Bill and Sunil,

Thanks for the response. Please find below the output and let me know if it is possible to remove /dev/disk/disk9_p2 entry from /etc/lvmtab.

# diskinfo /dev/rdisk/disk9_p2
diskinfo: can't open /dev/rdisk/disk9_p2: I/O error

< root@ > [vi: (root) pts/0]
#
# ioscan -fnC disk |grep -i no_hw

< root@ > [vi: (root) pts/0]
#

Thanks
Gaby

You asked this in another thread already, right?

Why opening a new one?

Looks like a bad disk.

Please post
