I have to Full Bus Mode setting and alternate path setting.
how to configration full bus mode ?

Hi,

if you want to connect the ds2300 to dual SCSI controller of the same host, you must set up the ds2300 to split bus mode.

Hi,

read the doc:
"hp StorageWorks disk system 2300
user's guide"

http://h200006.www2.hp.com/bc/docs/support/SupportManual/lpg29283/lpg29283.pdf

You have to put it in split bus mode or change the scsi id off on card.
You must change the scsi id to a not used id.

Change your scsi id in SERvice mode at the startup screen
