CD stuck in CDROM (Oracle CD)

[Chris Fadrowski]

We are trying to install a new version of Oracle 9.2 in my V class, however, after mounting the cdrom using

mount -F cdfs -o rr /dev/dsk/c4t0d0 /cdrom

it's stuck and wont' come out of the drive. I can mount and unmount the cdrom but it won't eject.. Anyone know how to get this cd out? i am thinking that a reboot is the only way.

Hi,

you could try and use a paperclip to open the cdron drive if this does not help reboot is the only option. Did you use pfs_mount to mount the cdrom ?

HTH,

try doing this
#fuser -kuc /dev/dsk/c4t0d0
#umount /cdrom

See if it ejects!!
all the best

oh boy, maybe i spoke to soon. this morning mounting the cdrom does not work. It's "not responding".. yesterday i could mount and unmount without a problem, just not eject the cd. Today it wont' even mount.

i tried the paper clip however, i don't find this to work. When i insert the paper clip, it seems as if nothing in behind it. i think a reboot is the only option.

Hi,
In my opinion, Bharat's solution should work, if it doesn't help. Reboot should be the next step.
By the way, to mount a oracle cd, you have to use pfs_mount/pfs_umount as follows:
1. add a line to /etc/pfs_fstab file in this format:
device_name mount_point filesystem_type translation_method
Example
/dev/dsk/c0t1d0 /SD_CDROM pfs-rrip xlat=unix 0 0
2. log in as root and run the following files:
# nohup /usr/sbin/pfs_mountd &
# nohup /usr/sbin/pfsd &
3. Please the CD-ROM in the CD-ROM drive, run the following to mount the CD-ROM:
# /usr/sbin/pfs_mount /SD_CDROM
4. Exit the root account:
# exit
5. log in as oracle and change dir to /SD_CDROM to install the software.

Hope this can help.

No you don't have use pfs_mount to mount the Oracle CDs if you have the patches installed that enable mount to handle Rock Ridge format CDs. It appears that Chris does have those patches installed so the mount command given will work fine.

If you are not able to do anything with the CD drive today, I would first make sure that it shows up in ioscan.

What errors does mount give when you try to mount the CD?

When installing Oracle be ABSOLUTELY sure that you do NOT cd into the cdrom mount point to start the installer. That will thoroughly mess you up when it is time to change CDs. Invoke the Oracle installer from Oracles home directory or some other location by specifying the full path to the installer.

Try power OFF/ON CDROM button only and you already aware that eject will only work if cdrom file system is unmounted from UNIX.

Try using one of the large paperclips. In some cases I have found you may have to insert the paperclip pretty far depending on the design of the drive. If after the reboot it is unresponsive I would suspect a bad drive. You may want to consider swapping it to confirm. If it is in hotswap enclosure you can do this very quickly.
