Hi Stefan,

i have a similar configuration:

DSS on a box with some TBs and QLA234X Dualport in Targetmode

are you able to rescan the vmhba?
how much capacity?
-> /proc/vmware/scsi/vmhba#/T:L
-> VI-Client -> Configuration -> Storage Adapters -> T:L
-> VI-Client -> Configuration -> Storage -> Add Storage

4 days ago i had an issue reporting the lun capacity as none instead of for instance 500GB. My problem was a bad GBIC on host side in my fc switch. After replacing all was fine. I saw some errors on switch level and /var/log/vmkernel

I could also try to use the fdisk command for creating partitions and formating with vmfs3.

- esxcfg-vmhbadevs -> which /dev/sd# for a given vmhbaC:T:L
- fdisk /dev/sd#

come back with any questions regarding ESX3 and DSS on that place
