[Veritas-bu] Only 128 drives allowed on Linux?!?

2009-06-11 Thread rsavage 

We are curretly having a problem with the robot daemon going down. We are 
running windows 2003 x64 with an EMC 4406 VTL. We have 168 tape drives 
configured but can only have about 50 running at one time. We have had up to 80 
jobs running at once but about every 3-4 days the robot daemon goes down and we 
have to reboot the NBU infrastructure of the master and media server. We then 
stagger the backups and it works fine. 

Right now we have a limit to the number of jobs that can start. EMC and Veritas 
are looking into the issue.

We just upgraded to 6.5.3 about 2 months ago.

2009-06-10 Thread tim burlowski 
Page 71 of the Device Config Guide references this obliquely.
I can't find a technote, but I am working on getting one written as I've
answered this question a fair number of times internally.

I got a private follow-up note explaining to me why a person might want to
do this. It went something like this.

My de-duping VTL doesn't know know how to de-dupe an MPX image, therefore I
want to stop MPX'ing. In order to still perform my backups in a reasonable
amount of time, I need 180+ drives.

Is that the situation you are facing?

I am not sure about the license side of the equation, but 128 drives is the
limit.

 

Are you able to keep 128 drives, virtual or otherwise, streaming data at a
reasonable rate on this linux server?

Hello everyone

 

Today I encountered quite a strange behavior in NetBackup (6.5.3.1). For a
couple of months we now use SLES10 linux server as media servers in our
company and recently we also bought a couple of VTLs. When I started testing
the VTLs with our linux machines I quickly got to understand that linux (out
of the box SLES10SP2) has a limit of tape devices of 128. But since we would
like to use more than that on our media server (the VTLs can offer up to 240
drives per partition) we let our linux engineering guys modify the kernel
settings so that we can generate up to 1024 tape devices on the servers.

Now, everything went fine and I got 200 tape devices on my linux server (100
drives from 2 different VTLs). But now NetBackup seems to have a problem
with it: Every time I start NBU the entire media management demons stop
working after a couple of seconds and the only one that stays running is
‘vmd’. After hours of googleing, searching through the logfiles I finally
saw the following line in ‘/var/log/messages’ when I ran ‘ltid’ with the
‘-v’-option:

 

ltid[4709]: The currently licensed version allows up to 128 drives per
server.  You have configured 200 drives.

 

What exactly does it mean? What license? Is there a license for this at all
or is it just Symantec’s way of telling me that I should not tamper with the
standard linux kernels?

 

Anyone got an idea how to get rid of this limitation?

 

Any help appreciated!

[Veritas-bu] Only 128 drives allowed on Linux?!?

2009-06-03 Thread Jim H 

Post subject: Only 128 drives allowed on Linux?!?

ltid[4709]: The currently licensed version allows up to 128 drives per server. 
You have configured 200 drives. 

What exactly does it mean? What license? Is there a license for this at all or 
is it just Symantec’s way of telling me that I should not tamper with the 
standard linux kernels? 

Anyone got an idea how to get rid of this limitation? 


There is a limit of 128 drives per media server in NBU, and I don't think there 
is any getting around it. The message is misleading as it seems to imply it is 
a licensing issue.
