Unable to eject CDROM

[Chakravarthi]

Unable to eject CDROM from a HP-UX server, so what needs to be checked,

Not mounted

[Pete Randall]

Mount it.

Unmount it.

Eject it.



HTH,

If you are still having problems after following Pete's suggestion, then get "lsof" to determine what if anything has it in use:

Hi,

you don't have eject command (like in solaris) in hp-ux to eject a cdrom.
#bdf
if you could see /cdrom
#umount /cdrom
press the button, CD comes out. if not
#fuser -k /cdrom
#umount /cdrom

[Stefan Farrelly]

If its not mounted then only 2 things to do;

1. power cycle the CD unit. You should be able to do this without rebooting the server, or else reboot the server.
2. if it still wont eject use a paperclip and insert into the manual eject hole on the front and press hard to force an eject.

[Ken Hubnik_2]

Make sure no one is in /cdrom.
fuser -c /cdrom.

Hi,

if the umounting doesn't work you can do following:

?? reboot with holding down the CDROm eject button, then the CDROM will successfully.

You should check if the current SCSI, DIAGNOSTICS, FILESYSTEM patches are installed.

Best regards,
Armin

Hi,

I have seen this before when a CD-ROM is mounted using pfs_mount and hasn't been unmounted. Try doing an 'fuser' command on your CD-ROM disk device to see if any process is holding it open.

Hi,

what the John poff is also right, check for any pfs process, if nobody using cdrom
#pfs_umount /cdrom
if still the CD is not coming out kill all pfs process

[Steven E. Protter]

fuser -cuk /cdrom

assuming cdrom is the directory you mounted the filesystem on.

This will kill any processes on it, including telnet or X-Windows sessions, then you can unmout it and reject it.

This pretty much has to work, though it might hose your pfs_mount processes and start generating console messages about NFS issues.

Best practice is to follow the advice above and stop those nasty pfs proceses. I have scripts for that purpose, let me know if you want them.

Of course my sledgehammer approach will most certainly get the cd out of the drive for you.
