Tape drives issue

Hi Dears, Recently I connected a new media server to tape library, Below is the result of cfgadm command on Solaris media server.

OS just seen 1 drive as tape drive and other drives are unavailable but connected and configured!

Whats your Idea to troubleshooting?

PS: I checked zoning and everythings are normal and driver is installed on media server and kernel modules(sg,st,qla2xxx) are loaded

Thanks
