SCSI read error

[Ravinder Singh Gill]

I have identified that it is c8t2d0 that is having the SCSI read error. What do I do next to resolve the problem?

Hi,

One error or more errors ? If you have several errors, change the disk for a new one.

If you need more info on how to remove/add the disk, please add info about your system.

What kind of disk (internal/external) ?
what kind of system and hpux version ?
mirrored ?
lvm/vxvm ?

Regards,
Robert-Jan

This is an external disk, to my knowledge it has the mirrored version on it. The same error is appearing multiple times. It is HPUX 11. or 11.i (off the top of my head).

Ps it is LVM

[Robert-Jan Goossens_1]

could you post or attach the output of

(mirror check + hot swap check)

# vgdisplay -v

# ioscan -fnkCdisk

[Sudeesh]

pvdisplay -v |grep -i stale

Will list you the stale mirrored extends. If it is in large number I would suggest you to immediatly register a HP support call with Response Center, rather waiting for other options.

good question from Sudeesh, I am having the impression you have a spare disk (right) ?

If not call your support services and have them replace the disk.

Hi,

#strings /etc/lvmtab

Will let you know the VG which resides on this disk. &

#lvdisplay -v /dev/thatvg/lvol* |more
will give you the lvols which are spread on that disk & wheather they are mirroed or not.

HTH,
Devender

Thanks guys, called HP and they will be replacing the disk. They said it is a Fibre attached disk. Would this require an outage do you know? I mean the system to be shutdown or would it be hot swappable?

[Ravinder Singh Gill]

Thanks for your help guys. I logged a call with HP and after doing a few tests they came out and replaced the disk.
