dd failing

[Smita Haldankar]

Hi all,

I have a HP 9000 D370 with dual cpu connected to a Model 10 dik array. I am having Informix DB running on it.I have 2 logical volume in a 4 GB disk which is th member of the disk array, i am using as a raw chunks for my DB .

while taking backup with ontape -s ( which is a level 0 archive) the backup fails.And gives:

io read chunk 47,pagenum 21838 , pagecnt 1 --> errno=16

when i tried
dd if=/dev/vg09/rlvol1 of =/dev/rmt/0m bs=4096

it goes thru.

when I tried for the 2 logincal volume rlvol2 it fails and gives

dd read error device busy.

note: when noticed the fault LED is glowing after the failure.

how can i recover the 2nd logical volume.pls help me??

thanks in advance

Do you have mstm support + installed:

if not:
Connect to gridmanager via RS232 terminal direct or preferable the cu command from your OS and give the output of the Presentation screen which contains f/w info and the UEL (Maintenance menu - log)

dd read error device busy.

>note: when noticed the fault LED is glowing >after the failure.
A fault led on a Nike only means hardware failure of some sort. One of your disks may be in a failing state. Do you have the Lun in a mirrored raid or a parity raid?

>how can i recover the 2nd logical volume.pls >help me??
Let's start by seeing why the fault led is on.
Perhaps your lun is inaccessable until the hw is repaired/reseated.. You really need to post mstm tools->info->run output to get all the information quickly. After finding out what's wrong with the array your vg and lv more than likely will come back up.

just do a vgdisplay -v vg....
and lvdisplay -v /dev/vg.../lvol..
to see the state of the LVM structures.

Later,
Bill
