Can not mount Oracle CD using pfs.

[Gino Castoldi_2]

Hi,

Server: D250 HP-UX 11.0 DVD-ROM drive.
OS version Sept 2001 & Support Plus Sept 2001.
I also installed these three patches for PFS.
PHKL_21586 (PHKL_26448 has been recalled by HP)
PHKL_26450, PHCO_26449.

NFS is running, 'rpcinfo -p' lists nfs & mountd

When I ran the pfs mount commands it failed with these error messages:

pfs_mountd.rpc: Can't open /dev/dsk/c2t2d0: Device busy pfs_mount: /dev/dsk/c2t2d0 on /cdrom: open failed: Device busy pfs_mount: giving up on /cdrom

When I run the 'bdf' command the terminal session hangs up with this error message.
"NFS server bosov2 not responding still trying"

After that I can not kill the process and I have to reboot to clear up this problem.

There are no processes that are on the /cdrom
mount point (I used lsof to check).

Here is the /etc/pfs_fstab file:
/dev/dsk/c2t2d0 /cdrom pfs-rrip retry=3,soft,intr,xlat=unix 1 0

Any ideas as to what is wrong?

10 points to any good answer.
Thank you Gino.

Gino,

you have 2 options,...

1. Use the old pfsd and pfs_mountd daemons, and then the pfs_mount command (well documented here in the forums).

2. Use the patch mentioned above, but use 'mount -F cdfs -o cdcase -xlat /dev/dsk/c0t0d0 /cdrom' instead.

it sounds lile you mixed the two strategies, hence why it freezes up!

Share and Enjoy! Ian

Hello,

I think you should consult this Technical Knowledge Base document KBAN00000252:

http://www2.itrc.hp.com/service/cki/search.do?category=c0&docType=Security&docType=Patch&docType=EngineerNotes&docType=BugReports&docType=Hardware&docType=ReferenceMaterials&docType=ThirdParty&searchString=KBAN00000252&search.y=10&search.x=53&mode=id&admit=-1335382922+1035553687540+28353475&searchCrit=allwords

I used to do the pfs mount like you until this doc was revealed to me. Take note of the section entitled "Undo incorrect Oracle instructions if used"

Hope this helps

Gino,

Are you using a remote server's cdrom ? If so umoumt cdrom on client before umounting on server.

Try stopping all the pfs processes. Restart the NFS services (/sbin/init.d/nfs.client stop /sbin/init.d/nfs.server stop) restarted them and then manually mount the cd and manually start pfs.

mount -o ro /dev/dsk/xxxxxx /cdrom
/usr/sbin/pfsd&
/usr/sbin/pfsmountd&

Then try your pfs mount command

[Gino Castoldi_2]

Hi Ian,

What you are saying is use either step 1 or
step 2 correct?

I'll try both steps (we're using a test server for this).

Thank you Gino.

When you have a system running with the three patches, you don't need pfs. never, ever.

Edit /etc/fstab, and add rr to the cd entry:

/dev/cd0 /cdrom cdfs ro,rr,noauto 0 0

modify /dev/cd0 to be your device and /cdrom to be your mount point. Then just say

# mount /cdrom

Done.

A possible solution:

Install the patch - PHKL_27224. That may solve the issue!

A lot of options to try (TKB# 2200219195):

Gino,

Yes that is what I meant, Option 1 or Option 2.

Harry also has some good pointers in his posting.

What I have arranged with our DBAs here is to set aside several lvols on a remote server, and copy each CD to those lvols and share them around each Server as NFS Mount Points.

That way we only go through the pain of getting the CD Mount Options correct once, then simply make the data available through all the Network.

Share and Enjoy! Ian

Gino,

(1) Remove /etc/pfs_fstab
(2) stop NFS by changing /etc/rc.config.d/nfsconf, client and server to 0
(3) Make sure you have no mounting of your cdrom in /etc/fstab
(4) reboot
(5) start the pfs daemons
(6) mount cd using pfs_mount

live free or die

You gave us all 10 points. Not that you will hear anyone complain, but I guess we all like to know, which of these solutions helped you solve /your/ problem.

Without a browser change, I'm now also experiencing the "Reply button waaaaaaay right" problem.

Oracle installs have always been of, um, questionable robustness (I first installed 5.1.b Beta Server for OS/2 and was a DBA through version 7). Wanted to point these articles out to my sysadmins and DBA, but got a failed search when using the link for KBAN00000252.

[H.Merijn Brand (procura]

The link Christopher posted is responsible for the width :/
Can't do much about it (except maybe not posting long links :P)

hi
try my script for both mounting and unmount the CDROM (in case it is already mounted)

Hope this helps!

Hi All,

Here's what I did to get the Oracle 8.0.5
CD-ROM (Rock-Rigde format) to mount.

I tried different ways of using the pfs commands and they didn't work so I installed the three patches which was recommended by HP
(one patch has since been recalled PHKL_26448)
PHKL_26448, PHKL_26450, PHCO_26449) and then I
could manually mount the CD-ROM and install
Oracle (OfO 8.0.5). This is the command I used and it worked fine.

# mount -F cdfs -o rr /dev/dsk/c2t2d0 /cdrom

Thank you again Gino.

Hello,

Sorry for causing the format problem; I'll try to be more aware of what I'm posting :^(.
