Vmware Restore from an imported image fails on san

Hello All,

 

We are facing a problem when we try to restore an imported Vmware image which its backup succeded in SAN mode.

The restore job fails with error "Error opening the snapshot disks using given transport mode: san Status 23"

 

and the vxms logs are showing :

Transport mode san failed pre-flight check. Ignoring.

 

09:46:08.0373 : g_vixInterfaceLogger:libvix.cpp:1805 <DEBUG> : [VFM_ESINFO] VixDiskLib: VixDiskLib_ConnectEx: No transport modes available to access disks. Error 3 (One of the parameters was invalid) at 4433.

09:46:08.0373 : g_vixInterfaceLogger:libvix.cpp:1805 <DEBUG> : [VFM_ESINFO] VixDiskLib: VixDiskLib_Disconnect: Disconnect.

09:46:08.0373 : g_vixInterfaceLogger:libvix.cpp:1805 <DEBUG> : [VFM_ESINFO] 2019-09-26T09:46:08.373+02:00 info -[12000] [Originator@6876 sub=Default] Successfully released all resources.

 

The datastores are presented to the Media & Master servers.

The restore through nbd is successful.

 

we did another test by backuping the same VM throught the 2nd master via SAN and it completed succesfully.

This same backup was replicated to the 1st master and try to do the restore via SAN, also failed.

 

any ideas please?

 

thanks

    Hello All,

    We have found the problem and fixed it.

    On restore panel, we changed the server used for restore from the master server to the media server (it is normal because the media server is the one who can access to the datastores and not the master).

    On the master from where the VM was backed up, it is not necessary to change it, because the media server is already known as Vm backup host, but on the other side (replicated image) you must show to netbackup that the VMbackup host is the media server.

    I am marking this one as solution hopefully that can help the others.

    BR.

    Hello,

     

    was it ever working? The fact that it is an imported image is not probably relevant. Find a cause on SAN/Disk Mgmt. My tip is that your disks are Offline in the Disk management, which is sufficient for backups but not for restores.

    Regards

    M.

      Hello Michal,

      This is a new test, so never tested.

      Please what do you mean by "The fact that it is an imported image is not probably relevant. "

      The disks are Online in the Disk management, the restore works from the primary copy of both masters, it only fails using the imported image.

      should we try to select the media server in the BAR GUI instead of the master to try?

      Regards

      H.

        Hello,

        doublecheck that all datastores presented on source Master/Media Server are presented on target server, too.

        For a while a had an idea if a different mapping could not be a problem, but I think that VMware API should cope with this (for example, when datastore X is presented as Disk 4 to server A and as Disk 5 to server B). Try to choose the Restore as Alternate instead of Original, keeping every parameter the same.

        Regards

        Michal
