Thanks Bobby.

I'll try..

Hi,

Run the backup with -D5 added to the backup command and check the sso logs in /nsr/logs/sg/[group name].  This should give you more details on the reason for the unavailability of the SAN transport mode.  There's an example in the below article:

185186 : VADP backup fails indicating the "hotadd:san" transport modes are unavailable

I have a similar setup, although I'm running vSphere 5.5u1a and vCenter 5.5. For me, SAN transport mode works fine. What is the actual SAN storage array? Do you use FC, iSCSI?

We have Fujitsu DX60 and HP p2000 as SAN storage arrays - they both have vmware datastores. All equipment is connected through FC.

Bobby,

I tried to start "nsrvadp_save" with -D5 option but after several seconds app crashes:

Hi,

you mean it crashes in debug mode, but doesn't crash without debug?   You may need to open a Service Request with EMC Support in order to have the crash dump analysed.  There isn't much we can tell from the above, so we'd need to look at the full stack trace with windbg.  Alternatively, you can have a look at it yourself:
