My understanding is you cannot get 1000 FDX without auto/auto. We keep all our stuff on automatic.

Only on the older 10/100 NIC cards. They tightened up the RFC when gigabit came around. If it don't autoneg, something is wrong.

Would it not be better to hard code the nic speed than auto/auto ?

I have cleaned up some of our “DNS” problems, although they were not the clients in question, and will see how it goes tonight. It also turns out that the medias servers had “files dns” in /etc/nsswitch.conf whereas
the master had “dns host”. I’ve changed the master to match. They also changed the NIC cards on the master to 1GB instead of auto negotiate. So we will see what happens tonight. If it is a problem with hitting the DNS servers too hard it should get worse tonight.

Thank all of you for your suggestions.

Patrick,
That is strange. I’m wondering if something else is going on. I have seen situations where you beef up your environment and it introduces you to other problems that used to be masked by a limited
environment. With that many drives and that much memory, you are going to be able to queue up and run more jobs. If you are creating jobs faster, I wonder if you are running into name resolution problems now. Can you find out how loaded your DNS server is
during the same time frame? I have seen where one of the older NBU environments I had was pounding the DNS servers to the point that they were running 100% cpu. I thought 6.x was much better at this, but it could possibly be related to the way your Linux servers
are doing name caching and how hard they hit the DNS servers.
One other possibility would be the VTL. I’ve had better luck with the newer DataDomain’s from EMC than their older “DL’s”. It may be possible that they are slow in responding to requests when they
get busy, but I wouldn’t think those would show up as error 47’s.
Does /var/log/messages show anything around the same time frame?

Hi All,
The situation is getting crazy. Last night 17% of our backups failed with error code 47. It happened on only 6 of the 58 media servers. All the jobs were trying to backup up to one of two of the four VTL libraries. Looking at the
<16> and <32> errors in /usr/openv/netbackup/logs I see CORBA errors on 3 of the six and Robot Failures on the other three. While we have many 47 errors on the weekends, this is a first of this magnitude for a week day. The only change I am aware of is: last
week we increased the memory of 5 of the 6 media servers from 12GB to 32GB. Is it possible to have TOO much memory?
Environment:
RedHat Linux 64bit running 32Bit NetBackup 6.5.6
4 EMC VTL Libraries (sorry don’t know model #) 164 drives configured on each.
The failing clients are both UNIX and Windoze with one Oracle backup failure.
OH, and they only seem to happen between 23:00 and 04:00 (approximately)
ANY suggestions would be greatly appreciated.
