vcb and iscsi

Hello Group,

I wanted to test the new supported ISCSI Feature in VCB 1.03, but it doesn't work for me. I'm using Openfiler as ISCSI Target and the MS ISCSI Software Initiator for connecting to the LUNs. In previous Versions ISCSI full backup went fine, but in the actual Version vcbmounter cannot find the LUN. In Disk Management all LUNs are visible and I have access.

Are there any new parameters for vcbmounter?? I also cannot find a new Documentation of using ISCSI with VCB.

Output follows:

C:\PROGRA1\VMware\VMWARE4>vcbMounter.exe -a name:server03 -t file -L 6 -r C:\mnt\SERVER03 -h 192.168.XX.XX -u administrator -p XXX

Hello,

we just upgraded to the new vcb release and all of a sudden my backups are not working. Using Netbackup, getting the following error when running the vcbmounter command. Here's the error message, it differs from Weili's above where instead of failing to open LUN I get an unspecified error.

\[2007-08-28 15:13:29.114 'vcbMounter' 3464 error] Error: Error while opening disk blklst://snapshot-12308\[datastore1] servername/server.vmdk@vcbhost?xxxx/

xxxx: A virtual disk could not be opened. -- Cannot open disk file: Error : Disk library failed (Unspecified error).[/b] Unable to open 'blklst://snapshot-12308\[datastore1] servername/server.vmdk@vcbhost'. Failed to configure disk scsi0:0

Thanks.

Michael,

please ensure that you upgrade your ESX server and Virtual Center to the latest - ESX 3.0.2, Virtual Center 2.02 and VCb 1.0.3. I was having problems with new VCB in one of my clusters where I had upgraded the software and VC only, not the host servers. Upgrading all hosts on my other side of the cluster resolved this issue.

resolved. See message to michael below. Upgrade all ESX hosts to 3.0.2, as well as VC to 2.02 and VCB to 1.0.3. This is provided VCB was working prior to the upgrade
