A1000 Disk storage array

UNIX Solaris
1

I am new to the unix world. I have SunBlade 100 and A1000 Disk storage array with 12 Hard drives. I used SCSI card and SCSI cables to connect. When I do the format command,I can see disk storage as one disk instead of 12 disks as below. Could anybody can explain why?
What should I do in order to see 12 disks?

Thanks in advance.

the a1000 is a hardware raid. you can't the the disks, only luns mapped from the box. if you need more luns, you'll need to download "raid manager 6.xx" software from suns webpage. the software is needed to configure the a1000 array.
