vcb, CX3-10, Powerpath Dualport Adapter, recognizing VMFS/LUNs

Hi forum users,

Situation: ESX3.5; VC 2.5; W2K3 Backup Proxy, vcb 1.1, Dualport Adapter at the vcb Proxy with Powerpath installed.

The vmfs-LUNs are promoted with the correct Host-LUN IDs.

5 LUNs appearing correctly as basic disks and vcbSanDbg.exe shows "Lun contains VMFS/LVM Signatures"

Only one LUN making troubles - appearing NOT as Basic Disk but as unknown --> vcbSanDbg.exe says "Luns does not contain VMFS Luns".

Ok, we know - officially powerpath  were not be supported. But, if we had troubles using powerpath in the past, no LUN was recognized. Sometimes configs like this are function correctly.

So, we think, there is another fault in our config...

Any ideas, suggestions...

Following an outpout of vcbSanDbg.exe  with one correct recognized VMFS LUN an one wrong...
