Bobby,

 

We fought a weird issue like this for a couple of months. Some of our
backups would run and sometime they would just hang in the activity
monitor. We found a doc on Sunsolve that told described making the
following changes...

 

-------------------------------------------------------------------

1)

 

# echo 'do_tcp_fusion/W 0' | mdb -kw

 

The NetBackup processes will need to be restarted.

 

-----------------------------------------------------

2) To make the workaround persistent across the system boot:

 

Add following line in the /etc/system file.

 

set ip:do_tcp_fusion = 0

 

One needs to reboot the system before the workaround will take effect.

 

 

We were running a fresh install of Solaris 10 with nbu 5.1 MP5. If you
have a sunsolve account, search for do_tcp_fusion, hope this helps...

Subject: Re: [Veritas-bu] hanging or never starting jobs

 


I just recently upgraded our media & master servers from Solaris 9 to
Solaris 10. After doing the upgrade and reloading all 
our backup binaries etc etc., I'm have some problems with jobs running.
It shows the jobs starting and actually running but 
I never see any data transferring. In some of the activity details it
shows tape mounting positioning but never starts to write. 
In some of the other logs it has nothing in the job details. I can ping
the clients but seems no data transfers. 

This only happens to 10 - 20 clients. Always not the same ones and it
happens on different platforms. Not sure what to go 
after here. 

I'm running Netbackup 5.1 MP5 on solaris 10 media & master servers. My
environment is around 400 servers. Approximately 
35 Oracle DB's , 20 SQL DB's. Clients are everything from linux,
solaris, netware and of course windows. 

Any ideas would be appreciated.. 

Thanks
