I am trying to use CD ROM (hp unix 11), but ...
after inserting the CD, I am issuing the folowing command,
/usr/sbin/pfs_mount -t rrip -x unix /dev/dsk/c3t2d0 /cdrom
But getting the following error
/usr/sbin/pfs_mount: giving up on /cdrom
Do I need to start any process before using pfs_mount commnad?
Please ....?
Thanks in Advance
Syed

Re: Using CD ROM
The following is mandatory before using pfs-mount :
cd /tmp
nohup /usr/sbin/pfs_mountd ???v &
sleep 10
nohup /usr/sbin/pfsd 4 ???v &
sleep 10
Hope this helps,

Re: Using CD ROM
A little "add-on"
You might want to make a /etc/pfs_fstab file containing the following line.
/dev/cdrom /SD_CDROM pfs-rrip retry=3,soft,intr,xlat=unix 0 0
You can then mount every Oracle CD with a simple pfs_mount -a (!!! after starting the daemons !!!).
Another important issue. Do a
pfs_umount /SD_CDROM
directly after you stop using the CD. You can not get the CD out of the drive unless you do this ! After unmounting you may kill the pfs-daemons in reverse order.
Be carefull, PFS is a really tricky way to mount CD's.
Hope this helps,

Re: Using CD ROM
for PFS to be able to work, you need to have "NFS" up and running, at least the "portmapper" (i.e. "rpcbind").

Re: Using CD ROM
you have to start two pfs processes before you do pfs_mount,
# nohup pfs_mountd &
# nohup pfsd &
Now mount the cdrom,
/usr/sbin/pfs_mount -t rrip -x unix /dev/dsk/c3t2d0 /cdrom
Hope this helps.

Re: Using CD ROM
# kill pid_of_pfsd
# kill pid_of_pfs_mountd
Be warned that if you mess up while using pfs daemons, it can require a reboot of your system to clean up.
If you do a search (on the left-hand menu) and type if 'pfs daemon' you will see lots of threads on the usage of the pfs daemons.

SolutionOnce you have finished using the cdrom, installing whatever product is there in cdrom, you unmount the cdrom,
pfs_umount /cdrom
Then look for the pfs processes and kill them,
ps -ef |grep pfs
you will see 4 processes, pfsd, pfs_mountd, rpc.pfsd, rpc.pfs_mountd, kill them in this order pfsd, pfs_mountd, rpc.pfsd and rpc.pfs_mountd
Hope this helps.
