Warning on DAS Backup

[cwilson]

Hi All,

I have two esx hosts out of the twenty that we backup that use DAS for their vm's. One of these servers reports a Warning on every vm in the backup job each time its run. The other server completes successfully. The proxy setting is set to automatic on both.

I am trying to understand why this one server reports this error on each backup. The warning is the: unable to establish connection directly to the san volume.

As mentioned though, i do not get this error on the other host, it completes successfully and 'is' backing up the vm since the size changes between backups.

We are running version 6.0.0.153

Any ideas or thoughts would be helpful.

Corey, are both hosts processed by the same proxy? Am I understanding you right that the second host is backed up using Direct SAN mode and the first one fails over to Network?

Hi Foggy,

They are both using the same proxy. I have only one backup proxy configured since it appears only one can be created. The proxy setting for both jobs is set to 'Automatic selection'. Both hosts have vm's on local das, yet only one host complains during backup where the other completes without any warnings.

Can you see the VMFS volumes for both storages in the Disk Management snap-in on the proxy machine?

What do you mean by that? You can create as many proxies as you like! And with DAS, for best performance you do want at least one virtual proxy on each host.

The warning is the: unable to establish connection directly to the san volume.

Discussed this issue with the devs, and we would like to investigate this issue more closely (considering you are only using DAS, this is unexpected). If you could open a support case and PM me the ID, I would appreciate it a lot. Thanks!
