CVSDM issues

Jarheadatheart — Fri, 23 Apr 2010 12:13:35 GMT

I had to reinstall CVSDM 1.09.02 on one of my HP servers due to a crash. The system is an RP7420 running hp-ux 11.11

The install went perfectly no errors/warnings reported.

However if I run:
# armdiscover
This could take several minutes ...

Failed to obtain remote database interface to host: localhost

none of my arm command work at all..... anyone have any thoughts?

Is the SDM service running? Or did you even install the CVSDM server?

CVSDM is a two fileset product client and server. Run

swlist -l fileset |grep SDM

and post the output.

Yes services are running.

Yes I installed both files-sets.
# swlist -l fileset | grep SDM
# HPCVVACLI 1.09.02 hp StorageWorks Command View SDM - VA client
# HPCVVASVR 1.09.02 hp StorageWorks Command View SDM - va server

The old database may still be there form the previous installation. Do the two steps in the 4th reply from the bottom in
http://forums11.itrc.hp.com/service/forums/questionanswer.do?threadId=641446

The DeviceDBFile is not part of the fileset and does not get deleted during an swremove so you may be still using the old dbfile with the new install.

TTR, I already took those steps (to no avail)right after I did the re-install.

You should have two SDM server processes running, they are java jobs running out of /opt/sanmgr/jre/bin/PA_RISC2.0/java
Verify that they are running.

Check if there are any cvsdm errors in the sylog.

Ensure that there were no errors when you swinstall-ed cvsdm

If all else fails, uninstall both cvsdm server and client, *delete* the /opt/sanmgr directory tree and reinstall the cvsdm server and client.

Before re-installing also delete the /var/opt/sanmgr and /etc/opt/sanmgr directory trees.

Update:

I had to go out of town to work on a production system so I am back now and on task to fix this.

I stopeed the dialers renamed DeviceDBFile and started the dialer again and the error "java.lang.OutOfMemoryError: unable to create new native thread" appeared when I tried to run armdiscover........

I did a search for this error, but it all looks like a foreign language to me. Idea's?

Full error reads as "Remote discovery failed with exception: java.rmi.ServerError: Error occurred in server thread; nested exception is:
java.lang.OutOfMemoryError: unable to create new native thread"

most like the maxthreads value is too low. this is likely also mentioned in the swinstall log.

Re: CVSDM issues

Torsten. — Tue, 04 May 2010 15:45:05 GMT

max_thread_proc is the parameter.

Re: CVSDM issues

Jarheadatheart — Tue, 04 May 2010 16:15:58 GMT

Torsten, do you happen to kno what file that parameter is in?

Re: CVSDM issues

Torsten. — Tue, 04 May 2010 16:22:06 GMT

It's a kernel parameter, normally set to 64. Increase it.

This error could also be the result of java requesting a large shared memory segment and the server does not have enough contiguous memory to allocate one.
This error may be totally different than the original error, in this case, java can't start up, the original error was that you could not see the disks.

You could try starting the dialer service again at a later time when the server activity is much less and possibly more memory is available.

right!

Should be PTHREAD_THREADS_MAX and _SC_THREAD_THREADS_MAX defined in /usr/include/limits.h.

but they aren't there.

Re: CVSDM issues

What is the value of max_thread_proc?

Torsten, I get a pattern not found.
