Oracle 8i install and pfs_umount...

Hello all,

I am trying to install Oracle 8i on an HPUX 11.0 system. The cd is pfs_mounted and we ran the "runInstaller" from outside the /cdrom directory. However, Oracle is asking for the second cd and of course we cannot pfs_umount because the device is busy. Can we force the umount? or is there another way?

Thank you all,

Kill the pfs daemon and then try to unmount the cdrom drive.

you can use fuser -cu /cdrom to see who is using /cdrom directory

fuser -ck to kill the process and you should be able to unmount

Good Luck..

Hi Sally:

See if this very detailed enumeration of procedure given by Wodisch solves your problem:,11866,0x5de1f9beca68d511abcd0090277a778c,00.html

Hi Sally:

I did this two weeks ago. I saw immediately that there was a flaw in the install sequence. If you did not cd to /cdrom and then ran ./runInstaller then you should be ok.

I hope that you ran from /home/oracle or / and did a /cdrom/runInstaller. In that case, open another window, pfs_umount /cdrom, install the 2nd disk and do a pfs_mount /cdrom and you should be okay.
If it ain't broke, I can fix that.

Re: Oracle 8i install and pfs_umount...

Best option with multiple oracle cd's is to stage them (copy) on disk space, we've had to do that before. As far as your install goes, you'll be better of uninstalling then staging, then performing the install. You will still need to peform the pfs_mount for this. Here is my process for pfs_mounts.


vi /etc/pfs_fstab and verify: /dev/dsk/cntndn /cdrom pfs-rrip xlat=unix 0 0
(or put these options on command line)
/usr/sbin/pfs_mountd &
/usr/sbin/pfsd &
/usr/sbin/pfs_mount /cdrom
/usr/sbin/pfs_umount /cdrom
ps ???ef|grep pfs
kill ???9 (pfsd)
kill ???9 (pfs_mountd)

pfs_umount ???c (cleanup files if have trouble pfs mounting)

Re: Oracle 8i install and pfs_umount...

Thank you all for the responses. My problem was that when I originally tried it I was in the /cdrom directory and then when I tried it again outside of the /cdrom directory, there were leftover processes. So killed off everything and it worked fine.
