Avamar Server 7.3.0-233 DDR SSL issue

Question

Hi,

Very new Avamar user here. GEN4T nodes leveraging DD9500 as the target.

I do have an active open SR with Support on this matter but I wanted to share this with the Community as the previous mentioned fixes (adding an entry in the local hosts files) etc do not work. I read up on this read for help Backup is incomplete because file "/ddr_files.xml" is missing

2016-10-07 10:22:57 avtar Error <10542>: Data Domain server "xxxxxxx.xx.xxxxx" open failed DDR result code: 5341, desc: SSL library error (Log #1)
2016-10-07 10:22:57 avtar Error <10509>: Problem logging into the DDR server:'', only GSAN communication was enabled. (Log #1)
2016-10-07 10:22:57 avtar FATAL <17964>: Backup is incomplete because file "/ddr_files.xml" is missing (Log #1)
2016-10-07 10:22:57 avtar FATAL <8941>: Fatal server connection problem, aborting initialization. Verify correct server address and login credentials. (Log #1)

This is happening for any Aix or Linux client attempting to backup to Data Domain through Avamar. Oddly enough we have also seen this error on one server attempting a Microsoft VSS backup then on others it is ok - baffling indeed.

The clients (all 7.3.0-233) connecting to Avamar Server are on the same VLAN as the Avamar Server and Data Domain (dedicated backup network). Firewall rules and routing do not come into play - so those have been omitted for possible causes.

If anyone has any pearls of wisdom on other potential workarounds or a permanent fix, I am open to ideas.

Thank you

-Matthew.

It turned out that the clients could NOT ping the IFGROUP -  ip addresses on the data domain for ddboost.  We found that Jumbo Frames was not completely setup on the Switch side. Once that was resolved, I was able to backup/restore fine.

Matthew,

the only time i see this is when my client is not able to connect DD. So I assume that all servers are dual-homed, with a dedicated network interface into backup network. You have absolutely ruled out that hosts are not trying to use their "public" interface to talk to DD, instead of them "backup" interface ? Do a tcpdump while backup is being initiated and see what's going on.

Jumbo Frames for backup infrastructure ? That sounds interesting.  What kind of improvements have you see with Jumbo Frames enabled ?

The link does not work...is there another way to get that information?
