HP Smart Array 6400 Series Controllers Support Guide, September 2007

NOTE: There may be system-specific cables required for connections to internal disks on servers
that support SmartArray with internal disks. Review the System Configuration Guides for your
system for more information.
Connecting External Storage
NOTE: Offset VHDCI cables must be used with the Smart Array Controller. Early versions of
the VHDCI cables do not accommodate side-by-side connection to the Smart Array Controller.
If your storage enclosure did not include the Offset VHDCI cables, you may need to order them.
See Table 2-3 for part numbers.
Two SCSI ports on the Smart Array 6402 Controller are available for connection to external
storage devices. Four ports on the Smart Array 6404 Controller are available for connection to
external storage devices.
To connect external storage to the Smart Array Controller, follow these steps:
1. On the rear of the server, connect the cable to the VHDCI connector on the Smart Array
Controller, and then tighten the lock screws on the cable connector.
2. Remove or open the access panel on the server.
3. Attach the other end of the cable to the HP StorageWorks™ or MSA 30 storage enclosure,
and then tighten the lock screws on the cable connector.
4. Label the cables. See Labeling the Cables, below.
5. Replace the access panel and secure it with the thumbscrews, as required.
CAUTION: Do not operate the server with the access panel removed for extended periods of
time. The access panel protects thermally sensitive components by ensuring the proper airflow
through the server, and also minimizes personal contact with hazardous energy levels.
CAUTION: In systems using external data storage, be sure that the server is the first unit powered
off and the last unit to be powered on. Doing this ensures that the system will not erroneously
mark the disk drives as “failed”.
Labeling the Cables
If the cables connecting the RAID controllers and the disk enclosures are switched, data can be
corrupted. HP strongly recommends that you label each cable with the following information:
• The controller slot number (stenciled on the system)
• The controller channel number
• The StorageWorks or MSA 30 disk enclosure the cable connects to (if there are multiple disk
enclosures)
• The SCSI bus connection ID on the disk enclosure I/O module. For example, SCSI Bus A or
SCSI Bus B on a StorageWorks.
Connecting Internal Storage
To connect internal storage devices, follow these steps:
1. If the storage device that you are adding is not hot-pluggable, power off the system.
2. Remove the access cover.
