we are using LSIs 3801E HBA to connect Infortrends S16S-G1030+JBOD (e.g. 32
disks, 16 x RAID0, 16 LUNs) to an AMD64 machine.

the Infortrend Box is momentarily configured with 9 LUNs.

When booting only 8 LUNs (da45 to da52) show up

da45 at mpt0 bus 0 target 10 lun 0
da45: <IFT S16S-G1030 361F> Fixed Direct Access SCSI-4 device
da45: 300.000MB/s transfers
da45: Command Queueing Enabled
da45: 1430288MB (2929229824 512 byte sectors: 255H 63S/T 182336C)
da46 at mpt0 bus 0 target 10 lun 1
.....
da52 at mpt0 bus 0 target 10 lun 7
da52: <IFT S16S-G1030 361F> Fixed Direct Access SCSI-4 device
da52: 300.000MB/s transfers
da52: Command Queueing Enabled
da52: 1430288MB (2929229824 512 byte sectors: 255H 63S/T 182336C)

"camcontrol reportluns 2:10"
shows: "9 LUNs found"

how to get more that 8 LUNs to map?

May be, some limitation somewhere in the code for MPT ?

any help would be appreciated.
