Open SCSI Integrator's Manual for NonStop S-Series Servers

Open SCSI Integrator’s Manual for NonStop Servers—422988-002
xi
About This Manual
This manual assists developers in designing devices for connection to NonStop S-series
servers through their SCSI-2 interface. This manual describes the SCSI-2 protocol
supported by the processor multifunction (PMF) customer-replaceable unit (CRU) and
the I/O multifunction (IOMF) CRU, provides information on developing interface
software, and describes the use of maintenance, diagnostic, and configuration software.
This manual describes information for NonStop S-series servers on G06.06 and
subsequent G-series RVUs.
Who Should Use This Manual
The following users of HP NonStop systems can use this manual as both a reference and
a tutorial when integrating a device into the Open SCSI environment:
•
System designers and planners
•
System developers
•
Programmers
•
Third parties who design SCSI devices for the Open SCSI environment
This manual assumes that its readers are proficient in computer languages, peripheral-
storage protocols such as SCSI-2, and related technologies. This manual also assumes
that readers are knowledgeable about the general process of adding devices to systems,
and that they need to know only the specific characteristics of Open SCSI hardware and
software.
What’s in This Manual
The following table describes the contents of each section in this manual.
Note. “NonStop S-series” refers to the server hardware. “G-series” refers to the server
software.
Section Title Abstract
1
Overview This section provides an overview of the Open
SCSI subsystem.
2 Prerequisites This section describes the areas you should be
familiar with before you integrate a device onto the
Open SCSI interface.
3 Integrating Hardware This section describes the hardware tasks required
to attach devices to the Open SCSI bus, and
specifications for the cables and connectors that
connect the SCSI devices to the SCSI bus.
4 The Open SCSI I/O
Process (IOP)
This section describes software topics associated
with writing device drivers to interface with the
Open SCSI I/O process (IOP).
