Solaris

Hi,
I have configured our SAN Storage to be connected to our new SUN T5220.
On the SAn it looks all fine
on the server I do not see any connection:
cfgadm -al

c1 scsi-bus connected configured unknown

usb2/4.2 unknown empty unconfigured ok
usb2/4.3 unknown empty unconfigured ok
usb2/4.4 unknown empty unconfigured ok
usb2/5 unknown empty unconfigured ok


the cableing for the SAn is connected to c4 and c7

currently already we have another storeage on c3 and c4

Questions:
Is it in generel possible to connect 2 different storage via c4 ?
Why so I not see anything with cfgadm -al ? also a cfgadm -c configure on any c*
does not change anything

thanks,

Manni
