Oracle and PFS_Mount

Chris Fadrowski — Mon, 28 Oct 2002 15:08:19 GMT

we constantly lock up our hpux system mounting oracle cd's using pfs_mount. Can some one direct me to a fix or patch for this. We do the nohup exercise as well, but have little luck. Are there any patches or procedures that may be of importance that i can check for or any bullet proof procedures available. Running HPUX 11.0 on a n4000.

Here is a reference to patches you can apply.

Hi:

You can do away with the pfs_mount and all its associated problems. For 11.0, download and apply the following three patches:

PHKL_26448
PHCO_26449
PHKL_26450

A reboot is required for this installation. When done, mount your CD thusly:

# mount -F cdfs -o rr /dev/dsk/cXdYtZ /cdrom

Regards!

On server where CD drive is located:

nohup /usr/sbin/pfs_mountd &
nohup pfsd &

pfs_mount -t rrip -x unix /dev/dsk/c0t6d0 /cdrom

Now, if you want to use the network and remotely access the tape drive, follow above instructions, and then follow these for the system without the CD drive:

nohup /usr/sbin/pfs_mountd &
nohup pfsd &

pfs_mount -o hard vpart1:/cdrom /SD_CDROM

Of course REMEMBER to use pfs_umount to unmount, otherwise you will have issues ejecting the CD.

Unmounting SEQUENCE for server WITHOUT cd:

cd /
pfs_umount /SD_CDROM

then, server with CD:

cd /
pfs_umount /cdrom

PHKL_26450 - s700_800 11.00 Rock Ridge extension for ISO-9660

Then :

==========================================================================================================

FYI

On HP-UX 11.11 :

First install the follow patches :

PHCO_25841 - s700_800 11.11 Add Rock Ridge extension to mount_cdfs(1M)

Then :

# mount -F cdfs -o rr /dev/dsk/cxtydz /cdrom

but doesn't PHKL_26448 have warnings attached to it? How safe is it?

Hi (again) Chris:

Yes, for 11.0, PHKL_26448 (and the companions patch for 11.11, PHKL_26520) have critical warnings associated with them, notably that these patches may cause a system panic when reading a CD/DVD with RockRidge extensions.

Unfortunately, in either release the aforementioned patches are but one of three required to enable RockRidge CDFS support with the native 'mount' command.

If you elect not to install, or if you deinstall, patch PHKL_26448 or PHKL_26520, you will need to use the 'pfs_mount' mechanism.

In my opinion, if you have a development server or even a production one where you can schedule possible downtime, you may want to "chance" the possible panic situation. I have used the patches in 11.11 without problems.

Regards!

The warning for the Rock Ridge patches is precautionary. A corner case CDROM format will cause the code to panic the system. It may never occur on Oracle CDROMs but there is no guarentee. I would put the patches on a test or development server and then export the result to a production server. Hopefully a replacement patch will out soon.

Hi there.
Follow JRF's recommendation with the patches.
We did this a few weeks ago.
It works perfect on different servers
( 2x N4000 / 1 V2500 / 1 K480 ).
No problems.

If you use pfs_mount to access the cd, don't do the installation from the /cdrom (or whatever you called it) folder.

If its a multi-cd install, you want be able to pfs_umount and switch cds. I learned this one the hard way.

Use this command from anywhere but the /cdrom folder.

/cdrom/runInstaller

X Windows required.

Standard advice for oracle db installes. See this script. Ignore the memory warning, just makes sure you have lots(min 256 MB).

I feel your pain

pfs_mount as instructed in the oracle cd

pfs_umount /dev/rdsk/device, for ex:
/dev/rdsk/c0t0d0

For "stuck" cd's
pfs_umount -c /dev/rdsk/c0t0d0

mount syntax for different cd's

pfs_mount
-t iso9660 -x unix /dev/rdsk/c0t0d0 /SD_CDROM

or
pfs_mount -t rrip -x unix /dev/rdsk/c0t0d0 /SD_CDROM

I have the Sept 2002 qpack installed -
