NFS in between HP-UX & Red Hat Linux

praveen.. — Mon, 19 Feb 2007 01:37:12 GMT

Hi,
Can I mount a hp-ux file systems to red hat linux using NFS?

Please suggest. Thanks

Shalom,

Absolutely.

One possible problem. RH has NFS Version 4 built in. Has for some time.

It should be able to accept the NFS v3 client that ships with HP-UX 11.11 or the NFS v4 client that can be added into HP-UX 11.23

I used to have a mixed environment in my home lab in the US and had no issues at all with NFS mounting.

Linux was totally able to mount any shared nfs filesystem on the HP-9000 boxes which were D classes running 11.11 and NFS v3.

Hi,

Yes. Once you have exported the file system on the HP-UX server, you go on the linux server and issue the mount command.

Hi,
OS: HP-UX 11.23

Please suggest

Thanks

Shalom again,

Last I saw, it was available on http://software.hp.com.

It may have been integrated into the core OS.

swlist -l product | grep nfs

hi,

try the mount operations before you attempt to install any additional software.

If you encounter any errors, post them here for us to analyse.

this is the current softare installed:

is it hang?

Hi Yogeraaj,
I tried to mount but nothing is happening..
command is just not being completed.

what does it mean:
PHKL_32713 1.0 nfs client hang; cache FS umount

Thanks

Yogeeraj_1 — Mon, 19 Feb 2007 03:32:28 GMT

hi vipin,

PHKL_32713 is a patch that has been installed on your system.

Did you export the file system on the HP-UX before you attempted the mount on the Linux server?

Seems to be conflicting information out there or HP pulled the upgrade.

I apologize for posting that NFS v4 was supported on 11.23.

HP has promised it will be supported on 11.31.

I would bet a few bucks that at one point I saw an NFS v4 depot on software.hp.com

I apologize for my error.

Please suggest from where i can download the nfs package for hp-ux 11.23

sothat I can mount its directory to Red Hat Linux system

current package is :

NFS Version 3 is part of the Core OS.

That is good enough to proceed with your original objective.

Nothing further other then patching to be done with the HP-UX box here.

Dave Olker — Tue, 20 Feb 2007 12:26:57 GMT

Hi Praveen,

Have you actually tried mounting the filesystem and had a problem or are you just asking if it's possible? If you're just asking - yes, it's possible and works just fine. If you're seeing a problem please tell us what the problem is so we can help isolate it.

By the way, NFSv4 has never been offered for 11.23, ever. It is available on 11i v3 (11.31) but not on 11i v2 (11.23). However, even if your server supports NFSv4, every server I've ever seen will always negotiate the highest available NFS version supported by both the client and server. So if you're using a RedHat server that supports NFSv4 and an HP-UX client that only supports NFSv3 you'll get a V3 mount without incident.

Please tell us if you're actually seeing a problem when mounting between HP-UX and RedHat.

Thanks,

Dave

I tried to mount HP servers local directory to Red Hat Linux server but I am not able to mount it.

When i give the below command on Red Hat Linux:
# mount -t nfs HP_SERVER_IP:/Reomte_Directory /Local_Directory

process is going on...I need to kill it everytime using C

Please suggest,

what to install and from where I can download the package.

Thanks

Re: NFS in between HP-UX & Red Hat Linux

Dave Olker — Tue, 20 Feb 2007 13:10:17 GMT

From the RedHat system, try issuing these commands:

# rpcinfo -t nfs
program 100003 version 2 ready and waiting
program 100003 version 3 ready and waiting

# rpcinfo -t mount
program 100005 version 1 ready and waiting
rpcinfo: RPC: Program/version mismatch; low version = 1, high version = 3
program 100005 version 2 is not available
program 100005 version 3 ready and waiting

# rpcinfo -t nlockmgr
program 100021 version 1 ready and waiting
rpcinfo: RPC: Procedure unavailable
program 100021 version 2 is not available
program 100021 version 3 ready and waiting
program 100021 version 4 ready and waiting

# rpcinfo -t status
program 100024 version 1 ready and waiting

This will at least confirm that the RedHat client can communicate with the various daemons on the HP-UX server.

If all of the above rpcinfo commands return the expected results then I would verify the target filesystem is exported as you expect. On the NFS server issue this command:

# cat /etc/xtab

Verify the filesystem is exported with the permissions you expect and verify the RedHat client is included in any access lists associated with the target filesystem.

I would then enable debug rpc.mountd logging on the HP-UX server:

# kill -17 $(ps -e | grep mountd | awk '{print $1}')

Finally, try the NFS mount again and see what kind of messages are logged in the /var/adm/mountd.log file on the NFS server. This should show the MOUNT request coming in from the RedHat system and whether it is accepted or denied.

This will hopefully steer us in the right direction. There may be other data to collect, based on what this data shows, but this is what I'd collect first.

Regards,

Dave

None of these commands are working on red hat linux.

I need to kill every command using C

Please suggest.

On HP-UX, file system has been successfully exported, i am able to mount them to other HP-UX server but not on red hat linux

Re: NFS in between HP-UX & Red Hat Linux

Dave Olker — Tue, 20 Feb 2007 15:20:43 GMT

Sounds like a networking problem. Are you able to communicate with any other networking protocols between these two systems?

linkloop
ping
ftp
rcp
telnet
ttcp
netperf

Do all of those programs work as expected between these two systems? If these programs work and only NFS doesn't then I'd suggest taking a network trace of the failing rpcinfo commands to see if the trace shows the RPC packet leaving the RedHat box and never getting a reply from the HP-UX box.

Is there any firewall between these systems? IP Filter? Anything else that would restrict packets destined for specific port numbers?
