Ambiguous Product ID
In the continuing effort to provide the price-performance advantage of the
latest disk technology and, at the same, timeprotect existing customer
investment, HP uses the same disk mechanism for both Single-Ended and
Differential disks. However, there is a layer of transparent hardware that
masks the electrical differences. This enables customers to continue to use
both their existing Single-Ended and their existing Differential interface
cards, but it requires some caution in connecting the disk device to the right
interface.
Since an Inquiry by a utility such as ODE MAPPER returns the same
Product ID (for example, ST34573WC) for both the Single-Ended and the
Differential version of the disk, you must use the HP Model ID to distinguish
the Single-Ended (for example, A3646A) from the Differential (for example,
A3647A).
As a work-around for SYSGEN, use the "WC"-suffix ID (for example, ST34573WC)
to bind to the Differential drivers; use the "N"-suffix ID (for example,
ST34573N) to bind to the Single-Ended drivers.
 |
CAUTION: It is critical that you connect the disk drive to the right
bus: Single-Ended to Single-Ended; Differential to Differential. Failure to
do so will result in unexpected system behavior.
