golden Image, nfs mount, boot error

[Syedfurquan]

Hello Experts,

I am using hp-ux 11.31 on rx6600. I have created a HP Integrity Virtual machines and trying to boot it from the golden image created on the physical host.

I have created golden image but when trying to boot getting below error:

1. nfs mount: 10.1.42.5:/var/opt/ignite/clients: Permission denied

>1. nfs mount: 10.1.42.5:/var/opt/ignite/clients: Permission denied

You could allow every machine to mount it if you can't figure out the right FQDN or IP.

[Syedfurquan]

10.1.42.5 is the same physical server on which ignite image I am creating and also HP Integrity virtual machine is created on this host only. Both the server is connected to a dedicated swith with no vlans created.

where I need to look to fix this error, "nfs mount: 10.1.42.5:/var/opt/ignite/clients: Permission denied"

This is a problem on the NFS server.  The NFS client isn't on the list of clients that can access the share RW.

[Syedfurquan]

Please find details :

showmount -e
export list for rx6600:
/var/opt/ignite/clients              10.1.42.5
/var/opt/ignite/archives/Rel_B.11.31 10.1.42.5

Here both /var/opt/ignite/clients have rw=10.1.42.5

/var/opt/ignite/archives/Rel_B.11.31 rw=10.1.42.5

Now where to look for the root cause.

[Dennis Handly]

10.1.42.5 is the IP of the NFS server.  What is the IP of the VM, the NFS client?

What does /usr/sbin/share show?

[Syedfurquan]

> 10.1.42.5 is the IP of the NFS server.  What is the IP of the VM, the NFS client?

SIce there is no OS on the vm so no IP assigned, but I have edited /etc/opt/ignite/instl_boottab and given the IP 10.1.42.12 which i want to give to VM.

tail /etc/opt/ignite/instl_boottab
# Example: (lines are intentionally commented out)
# 15.1.54.125                             # IP address usable by any client

currently no access to server since it is midnight so can't share  /usr/sbin/share show  o/p, will be able to share by morning only.

Please anyone share documents for creating golden image for hp-ux 11.31.

The latest Ignite/UX Administration manual is located here:

http://h20566.www2.hp.com/portal/site/hpsc/template.BINARYPORTLET/public/kb/docDisplay/resource.process/?spf_p.tpst=kbDocDisplay_ws_BI&spf_p.rid_kbDocDisplay=docDisplayResURL&javax.portlet.begCacheTok=com.vignette.cachetoken&spf_p.rst_kbDocDisplay=wsrp-resourceState%3DdocId%253Demr_na-c04015128-2%257CdocLocale%253Den_US&javax.portlet.endCacheTok=com.vignette.cachetoken

Here are the NFS options that the manual recommends (located on page 94 of the link above):

2. Set up NFS exports and check custom configuration files.

Because of preexisting Ignite-UX file system layouts, the locations of certain files are automatically moved when Ignite-UX Version C.7.9 or later is installed . These files are /opt/ ignite/Version, /var/opt/ignite/INDEX, and /var/opt/ignite/config.local.

In addition, certain other customer-created config files might need to be moved or edited.

First, edit /etc/exports or /etc/dfs/dfstab as appropriate for the version of HP-UX running on the Ignite-UX server.

For Ignite servers running HP-UX 11i v2 or earlier:

# cat /etc/exports

/opt/ignite/data -ro

/var/opt/ignite/config -ro

/var/opt/ignite/data -ro

/var/opt/ignite/clients -anon=2

# exportfs -a

For Ignite servers running HP-UX 11i v3:

# cat /etc/dfs/dfstab

share -F nfs -o ro /opt/ignite/data

share -F nfs -o ro /var/opt/ignite/data

share -F nfs -o anon=2 /var/opt/ignite/clients

# shareall

If there are any customer-created config files that are outside of the directories exported by NFS, they must be moved under /var/opt/ignite/data.

Hello Patrick,

Thanks for your response but I ma not able to download or open the documents... Can you please share any other link if have..

After downloading also it showing the documents as corrupt..

[Patrick Wallek]

Try some of the links from a google search:

https://www.google.com/#q=ignite-ux%20administration%20guide

http://www.lmgtfy.com/?q=ignite-ux+administrator+guide

Also -- Did you try the NFS options I mentioned?

[Torsten.]

Go to

http://www.hp.com/go/hpux-vpars-docs

and get "Using Golden Images with Virtual Partitions" - it has some good hints (even for virtual machines).


Also read the chapter

"Do Not Create Golden Images of the VM Host for Guest Installation"

in the HPVM guide!!!

Better copy the install media to your servers ignite repository and install a fresh guest. You may use golden images from this guest then.

[Dennis Handly]

>  /var/opt/ignite/clients   sec=sys,anon=2,rw=10.1.42.5   ""

This isn't the IP address of the NFS client.

[Syedfurquan]

10.1.42.5 is the ip of nfs server.

[Dennis Handly]

>10.1.42.5 is the IP of NFS server.

Which is useless.  It needs to have clients there.

[Syedfurquan]

Hello Denis,
Thanks for the response.
Ok I will make that changes. /var/opt/ignite/clients sec=sys, anon=2, rw=nfs client ip

but what about the 2nd error:
10.1.42.5:/var/opt/ignite/archives/Rel_B.11.31: Permission denied

As mentioned in my 1st post

Regards

[Dennis Handly]

>10.1.42.5:/var/opt/ignite/archives/Rel_B.11.31: Permission denied

You need to change both to list the NFS client IP/FQDN.

[Syedfurquan]

Hello All,

I tried to reconfigure everything. First I created a Golden Image archive and then configure the Ignite-UX server to recognize the golden image archive as per the guide found shared by Torsten.

As per Dennis suggestion I edited the /etc/dfs/dfstab file and make the entry for NFS client server which I am going to use now as 10.1.42.6 NFS client

10.1.42.5 NFS server.

But still getting both the error repeated as earlier;

NOTE:    NFS mount (/sbin/fs/nfs/mount -oro
         10.1.42.5:/var/opt/ignite/archives/Rel_B.11.31
         /tmp/ign_configure/archive_nfs) failed, see messages above.

nfs mount: 10.1.42.5:/var/opt/ignite/clients: Permission denied

         /var/opt/ignite/clients) failed, see messages above.
       * Using client directory: /var/opt/ignite/clients/0xB2B9223B8EC3

-               /var/opt/ignite/archives/Rel_B.11.31   sec=sys,anon=2,rw=10.1.42.6   ""

Any suggestion how to fixed it.

Syed

>I edited the /etc/dfs/dfstab file and make the entry for NFS client ... as 10.1.42.6 NFS client

My only suggestion now would be to completely remove the rw=... from dfstab and retry.

And quickly put it back after you're finished!

I'm surprised that the -oro mount for /var/opt/ignite/archives/Rel_B.11.31 also fails.  ??

[Patrick Wallek]

According to the Ignite Admin guide, the recommended NFS shares are:

For Ignite servers running HP-UX 11i v3:

# cat /etc/dfs/dfstab

share -F nfs -o ro /opt/ignite/data

share -F nfs -o ro /var/opt/ignite/data

share -F nfs -o anon=2 /var/opt/ignite/clients

[Syedfurquan]

Hello Expert,

Thanks to everyone for the support to fix my issue.

As per Dennis suggestion I tried removing the "rw=.." from /etc/dfs/dfstab and shared to everyone...

After this am able to boot the virtual machine from the archive image created on ignite server but the virtual machine is not booting it just get crashed after completing the start services...

  Start HP Virtual Machine Monitor ............................... BOOT

"Reboot of system has been requested -- rebooting..." This message comes after starting all teh services and vm get rebooted

attached all the logs related to it.... Appreciate if get any help on it...

[Matti_Kurkela]

For some reason, the startup script for HP Virtual Machine Monitor returns an exit value of 3, which tells the system that a reboot is needed. If that happens each time you try to boot the system, boot it to single user mode instead, and read /etc/rc.log and /etc/rc.log.OLD. Those log files might include a more descriptive error message from the Virtual Machine Monitor.

This error is probably not related to your /etc/dfs/dfstab change, unless the Virtual Machine Monitor is configured to use the share(s) you modified.

[Syedfurquan]

Hello Matti,

Thanks for the reply.

As per your suggestion I tried to boot the HP Integrity virtual machine in single user mode. Checked the logs rc.log and the only thing I get their is:

Start HP Virtual Machine Monitor

There is no rc.log.OLD.

I ma not able to get anythings from this logs. Please let me know if you can find something which will help me in resolving this issue.

This might be the problem.
