cdrom drive not opening HP Visualize B2000

Hi,
I'm trying to access the cdrom drive on this HP Visualize B2000 workstation running HP-UX 10.20, but the cdrom drive will not open when the eject button is pressed. The light flashes but it won't open.

Don't see a cdrom listed when I type " ioscan -fun" at terminal windows logged in as root and I don't see any files in the /dev/dsk named either c0t0d0 or c1t2d0 which are normally the ones you see for the cdrom drive.

Any suggestions? Thanks.

hi,

I think the cd-rom drive is not physically connected,(ie.the SCSI interface cable is not connected), kindly check it up, it should work once the scsi cable is connected.

If there is media in the drive, then it could be mounted and you need to unmount the drive before the door will open. Do a bdf and see if something is mounted on /cdrom or /SD_CDROM. If mounting the CD is set to happen on boot, it will be listed in /etc/fstab. You should be able to "umount /cdrom" or "umount /SD_CDROM" or umount whatever the name of the mount point actually is.

It does appear to be a hardware issue.

Any lights on the drive?

Shut down the workstation, open it up and check scsi and power connectors.

Also see if there is anything else on the scsi/ide chain that still works.

There is a powerlight that flashes on the cdrom drive when you try to eject, but it just doesn't eject. I have opened it with the old paperclip trick, but there was no stuck cdrom disk inside.

I opened up the box and the power and scsi cable connection were good. I can't mount and unmount the drive because there is no /cdrom or Sd-cdrom listed in SAM under periphel devices, nor as I said earlier with the ioscan -fun command.

I can work around the main problem by ftping into the box from a pc and copying the Tar file I needed to install my software onto this box. Customer never uses the cdrom anyway but it would be nice if this worked. Guess I can chalk it up to bad hardware. Customer has the option of purchasing new cdrom drive if he wants to pursue it further.

Thanks for the suggestions.
