symtab missing

[mannp]

I have an rp7420 running 11.11.
My /stand/dlkm/symtab file has disappeared, and despite following advice found elsewhere in the forums I can't seem to get it back. I have rebuilt the kernel both manually (using kmupdate and shutdown rather than reboot) and via SAM with no success. I see the following warnings in syslog:

WARNING: load_statsym: Could not open kernel symbol table The file "/stand/dlkm/symtab" does not exist or is unreadable.
The system is fine, but the Dynamically Loadable Kernel Modules feature will be disabled. Restore the file and reboot to enable Dynamically Loadable Kernel Modules.
WARNING: modpath: DLKM is not initialized
WARNING: modadm: DLKM is not initialized
WARNING: ioctl: DLKM is not initialized

This isn't causing me any problems other than my not being able to run sysdef:
ioctl: Function is not available

The system is still in the process of being built so all I have in the way of backups is an ignite tape of the initial O/S build, and I would rather not have to resort to that - or a re-install - unless I have to.

Anyone got any ideas?

Shalom,

Yes, restore it from the system backup or perhaps a similar system.

Its a file after all.

If you have ever done an Ignite make_tape_recovery it is possible to pull the file off of there.

If you have ever taken an fbackup of /stand you can recover the file from there.

If you have NEVER taken a backup probably someone can post the file for you if you can't get it on another system.

There is no need to reinstall. In my earlier stupid days (some would say those days never ended) I accidently erased files from the /stand filesystem. Since I actualy was not so stupid, I had my choice of three possible backups onsite to get the files back.

Oh, you need to recover the files from the Ignite tape.

Duh.

This thread says exactly how to do it.

Is symtab not system specific then?
If not then I can just pull it from the other nPAR - makes life much simpler :-)

[Steven E. Protter]

I think its safe to copy it in from another vpar. This is much simpler than getting it off the ignite tape.

There may be system specific information in the file, but my rp3440 systems have the same file.

/stand/dlkm/symtab

I copied the file across from the other nPAR, manually rebuilt the kernel - and am getting exactly the same error.
