G-2 Questions and Answers About the Smart Array 221 Controller
Q. I have several hard drives in my server and in the Compaq ProLiant
Storage System/U. What SCSI IDs do I assign for these drives?
A. Each hard drive must have a unique SCSI ID for each controller port. If
your drives are installed in a Compaq ProLiant Server, a Rack-
Mountable Compaq ProLiant Server, a Compaq ProLiant Storage
System/U (Models U1, U2, or UE), the SCSI IDs are automatically set
according to the bay in which the drives are installed and do not need to
be manually set.
Q. Should SCSI IDs in my system be consecutive?
A. No. The IDs of devices on each SCSI bus are not required to be
consecutive. However, IDs must be unique for each device on a single
SCSI bus.
Q. I ordered my server with a pre-installed Smart Array 221
Controller. Will the server ship with the SCSI cable that I will need
to connect to my Compaq ProLiant Storage System/U (Model U1,
U2 or UE)?
A. No, you will not receive the external SCSI cable with your server.
However, the required cable is supplied with Compaq ProLiant Storage
System/U enclosure.
Q. I want to connect a Compaq ProLiant Storage System/U (Model U1,
U2, or UE) to my server. Can I also connect the internal hard drives
in my server to the Smart Array 221 Controller?
A. No. If you connect one ProLiant Storage System (Model U1, U2, or UE)
to your server you cannot connect any internal hard drives in your server
to your Smart Array 221 Controller because the SCSI port will be used
externally. You can add an additional Smart Array 221 Controller to
your server to control any internal drives.

CAUTION: Do not interchange SCSI IDs after you configure your
Smart Array 221 Controller. Interchanging the SCSI IDs will result
in loss of data.
