Kavita Poonia — Sun, 14 Sep 2008 09:26:21 GMT

Hello techies,

I have an error on one of our HP-UX server

vmunix: SCSI: Request Timeout; Abort -- lbolt: -1452910104, dev: bc004000, io_id: cd6d

But I do not know how to proceed and what can be done to resolve this.This is for DVD-ROM

mccfwp25:/dev/dsk:>ls -li|grep -i 004000

Your DVD rom is coming as Claimed right now. Have to tried to run any DVD for checking purpose?

May be you need to replace the DVD drive, it may need maintenace.

Are you receiving these alerts frequenty. If yes then log a case with HP.

Thanks

Hi Kavita,

lbolt error generally came for disks, please cross check once again.
if this devise is belongs to DVD then better change the DVD drive and check again.

The device is DVD ROM only

So the problem is with CDROM.
It is not necessary that ibolt errors occurs with harddisk only

dev: bc004000

here first two character of "bc004000" (here bc) decide the device.

Hi sanjeev,

The problem is with DVD-ROM not with CD-ROM.

>>>>>>>> dev: bc004000

here first two character of "bc004000" (here bc) decide the device.

I did not understand the above line mentioned by you. What is the use of first two letters that are bc here ???????

hi,

I take it that its an internal dvdrom to the server, not an external one?

what server is it? and how is it attached? any thing else on the same bus?

it could just be down to bad termination on the scsi bus. If it shares the same bus as an external scsi connector on the server, check if there is a terminator installed. It should have one.

It could be a bad internal cable, as these have an inbuilt terminator in them.

Also is there a cd/dvd in the drive and mounted?

you can also test the drive in STM, but I bet its a bad terminator
