Backup VM fails part way with ANS9365E

[ellisdp]

Hi,

We are trying to use TSM BA Client 6.2.2 to do Full VM backups, using the vStorage API.

I have been able to back up a small (4GB) VM OK, but when I try larger VMs (30GB), these fail part way through (e.g. 30% complete), and I see the following error reported in "dsmerror.log":

06/27/2011 17:38:45 ANS9365E VMware vStorage API error.
TSM function name : vddksdkRead
TSM file : vmvddksdk.cpp (2232)
API return code : 1
API error message : Unknown error
06/27/2011 17:38:45 ANS0361I DIAG: ANS1111I VmProcessExtent(): vddksdkRead() rc=-1, startSector=35529216, numSectorsToRead=512
06/27/2011 17:38:49 ANS0238E The sequence of calls is invalid.
06/27/2011 17:38:49 ANS5283E The operation was unsuccessful.
06/27/2011 17:38:49 ANS4047E There is a read error on 'vmxxx'. The file is skipped.

06/27/2011 17:38:49 ANS4148E Full VM backup of Virtual Machine 'vmxxx' failed with RC 152

The VMs concerned are shut down; one was Windows and one was Linux. I have Googled this error and have not found an exact match. I guess there is something about the configuration of our VMs which is causing a problem for TSM, but I don't know what.

Any clues? Thanks.

Hi,
If you use SAN for backup try to set VMVSTORTRANSPORT=nbd and retry. It will eliminate SAN failure.

Thanks ... does that option only apply to v6.2.3 though? I get "invalid option" if I add that in my client options file.

I do not think we are using SAN backup at this point, anyway. The VMs are stored on a SAN, but I have just set up the backup with default options which I assume is a LAN backup.

Hello, do you have enough space available on your proxy host? Check you vmbackdir option.

Hello,

the better way is to zone your ESX LUN's to proxy host and then performing your backups. I use 6.2.3 client with TDP - so I'm able to perform full backups lanfree and incremetals through lan.

If you add option VMVSTORTRANSPORT to dsm.opt use this sintax:
VMVSTORTRANSPORT nbd
I thing that it's SAN problem because vStorage API returns error: vddksdkRead() rc=-1
