Re: ioscan shows disk claimed but diskinfo shows 0 bytes and no pvdisplay

hi can you post the O/Ps of both the ioscan as well as the diskinfo?

this can be a failing diks.

can you try reading some data from the disk?

dd if=/dev/dsk/cXtYdZ of=/dev/null

Re: ioscan shows disk claimed but diskinfo shows 0 bytes and no pvdisplay

Hi Tariq,

Probably the disk is gone bad. Still you can check.

Check the status of the disk through cstm:
# cstm
cstm>map
cstm>sel all <- to see all details
cstm>sel dev 20 <- (20 is the dev num for my disk)
cstm>info
cstm>il

Check the details.

You can also try removing the special files and then recreating it again.
# rmsf -H
# insf -eH

Also try the dd test.

Re: ioscan shows disk claimed but diskinfo shows 0 bytes and no pvdisplay

Hi Again,

Most probably the issue is disk going bad.
Check from cstm and also perform a full dd test on the disk.

PLease run following:

# insf -eH 0/1/1/1.2.0

Most probably you may not find it CLAIMED this time.

Re: ioscan shows disk claimed but diskinfo shows 0 bytes and no pvdisplay

Hi again:

Please verify :

0) instance numbers found in 2nd column of ioscan - duplicate or unique?

a) ll /stand/ioconfig - ll /etc/ioconfig (* permissions, ownership *)

b) ll /etc/inittab (* permissions, ownership *)

c) sdiff /etc/inittab /usr/newconfig/etc/inittab

d) read man page on ioinit, consider running '/sbin/ioinitrc -i' - I believe this will check for differences between kernel I/O mapping and /stand/ioconfig and provide errors found on man page

/sbin/ioinitrc -i
echo $?
man ioinit (* see error messages *)

Re: ioscan shows disk claimed but diskinfo shows 0 bytes and no pvdisplay

Hi

This is something like a DS 2120, right? So you only have one scsi controller going to both pri and alt boot disks. (* c2 *) But this is a c3 controller. Examine this controller.

Also, please post this report including start and stop times:

cstm<<-EOF

You got a tape drive and a disk on one scsi controller - that's a no no - tape drives get dedicated scsi controllers.

Shalom Tariq,

Add to your sequence.

insf -C disk

This before insf -e

Makes sure the disk is really there.

Still looks from the original question like the disk is dead. diskinfo is telling me that.

Re: ioscan shows disk claimed but diskinfo shows 0 bytes and no pvdisplay

when was the last time you rebooted this box?

uptime

why don't you just reboot?

Re: ioscan shows disk claimed but diskinfo shows 0 bytes and no pvdisplay

It's not this unusual.

The disk controller is still alive (CLAIMED in ioscan), but the disk mech is already dead (size of zero).

Replace the disk.

Hope this helps!
Regards
Torsten.

Re: ioscan shows disk claimed but diskinfo shows 0 bytes and no pvdisplay

Just out of curiostiy, have you even physically inspected for the indicated disk? If so is a fault light? If so have you pulled the disk out and then replaced it in an attempt to clear the fault light?

Do you know for sure that there is even a disk? Because I read this as there is no disk.
