HP Smart Array 6400 Series Controllers Support Guide, September 2007

Connecting the Cables and the StorageWorks or MSA 30 Disk Enclosures
The following rules govern how you can connect drives to a Smart Array 6400 Series controller:
• Each channel on the Smart Array Controller supports up to 14 drives.
• Port A1 (Channel 1) and Port A2 (Channel 2) each have two SCSI connectors, one for external
storage units and one for internal hard drives in the server.
• You cannot use the internal and external connectors on a channel at the same time. Each
channel can be used for internal or external devices, but not both.
CAUTION: If the internal and external connectors on the same channel are both connected to
storage and you attempt to boot, the following message displays:
1783 - Drive Array Controller Failure!
[Controller self-test failure (faliure code = 0093])
press “F1” to continue...
Unless this problem is fixed this controller will not be available upon boot.
The Smart Array Controller locks up if the system is booted.
CAUTION: If any data currently exists on the StorageWorks disk enclosure, back it up if you
want to retain the file system and the data. Configuring logical drives will destroy any data on
the disks.
IMPORTANT: Peripherals attached to any of the connectors must have a unique SCSI ID value
ranging from 0 to 15. Do not use ID 7, which is reserved for controller use. The SCSI ID value
determines the priority given to the device when it attempts to use the SCSI bus.
The supported HP StorageWorks and MSA 30 disk enclosures automatically set the SCSI IDs for
the physical disks they contain.
IMPORTANT: On 11i v2 and v3 systems, to preserve an existing configuration when replacing
an existing Smart Array Controller with a new Smart Array 6400 Series Controller, be sure to
reconnect the SCSI cables to the same channels on the replacement controller as the channels
they had been connected to on the original controller (Channel 1 to Channel 1, Channel 2 to
Channel 2).
NOTE: To verify whether internal disks are supported on the Smart Array Controller, see the
HP Smart Array Controller Support Matrix at:

To prevent signal degradation, SCSI buses require termination on both ends. In HP servers and
storage systems, the controller, SCSI cable, and backplane provide the required termination.
