networker issue with vmware backup through SAN transport mode

Question

Hello!

I'm new for networker. So ask for an answer.

We have vmware vsphere 5.0 (vCenter server + several ESXi servers). Besides Networker Server 8.1 SP1 is installed on another Windows 2008 R2 server. All servers are connected to common SAN. All LUNs which comprise of vmware datastores are presented to all servers. We had successfully backups through NBD transport mode but when we are trying to backup through SAN transport mode we receive an error:

nsrvadp_save: Requested transport modes "san" unavailable, only "nbd" available. Please change transport mode to "nbd" and retry backup.

We have capacity licensing model and license is active.

All requirements from “EMC NetWorker and VMware Integration Guide” are followed.

So we stuck on that issue.

Please advise us what could be wrong.

Thanks in advance!

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:

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: Problem signature:   Problem Event Name: APPCRASH   Application Name: nsrvadp_save.exe   Application Version: 8.1.1.2   Application Timestamp: 52e2d2b2   Fault Module Name: nsrvadp_save.exe   Fault Module Version: 8.1.1.2   Fault Module Timestamp: 52e2d2b2   Exception Code: c0000005   Exception Offset: 000000000001485b   OS Version: 6.1.7601.2.1.0.272.7   Locale ID: 1033   Additional Information 1: 1c13   Additional Information 2: 1c13b3433d73bfd02f3dd6aef15bb6e9   Additional Information 3: b169   Additional Information 4: b169fb4fb7594d3b44377c1f7ac75537

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:

windbg

file

open crash dump

!analyze -v
