SUMMARY Sbus SCSI Cards don't recognize Disk's in 12 slot multipack!

Hi Sunmanagers

Thanks for quick answer....I thought that I will receive such an answer but
I was not sure....thanks to Michael Lehmann he answered very quick and very
clear:

the Fast SCSI/Ethernet (FSBE/S) 501-2025 with 50 pin connector support only
7 devices (ID=0-6, 7 is the controller itself). The disks with IDs above 7
are not recognized. To use more than 7 devices on the same channel you need
at least a Wide SCSI card (68p connector)




Hi Sunmanagers

I use a Ultra 1 on 64bit modus (Solaris 8 with latest cluster) and have two
Sbus SCSI cards entered. On each Sbus SCSI card there is a 12 slot
multipack. Now on other systems (with PCI SCSI cards) I can use any/each
slot with disk's and all disk's will be recognized. On the system with Sbus
SCSI cards the system recognize only the first 4 slots with disk's.

Is there any limitation (probably because of SCSI) with Sbus SCSI cards. Is
with Sbus SCSI cards not possible to use Lun? Could I do something that all
slots could be used with disk's in the 12 slot multipack? Here the details
of the system:
