Guardian Procedure Calls Reference Manual

MODULE
A set of components that shares a hardware interconnection. A module is a subset of a
group. It is contained in a system enclosure, and contains one or more slots. In a NonStop
S-series server, there is exactly one module in a group. The valid range is from 1 through
99.
SLOT
A physical, labeled space in a module in which a CRU can be installed. The valid range
is from 1 through 999.
SUBDEVNUM
The subtype of the device. For more information about device subtypes see Appendix A:
Device Types and Subtypes.
FABRIC
X, Y, or both. These codes correspond to the possible fabric types:
FabricValue
X0
Y1
SACNAME
The name of the ServerNet addressable controller (SAC) located in the PMF CRU or IOMF
CRU.
SCSILUN
This 64-bit field is effectively a structure:
• The high-order 16 bits (two bytes) contain the partition number of the device; if the value
is zero, the device is not partitioned.
• The next four bytes are reserved.
• The low-order 16 bits (two bytes) contain the logical unit number (LUN) of the Open SCSI
device.
SCSITARGET
The SCSI ID of the Open SCSI device. This is the address used by the Open SCSI I/O process
to access the device.
More information about the definition of the specific_info field for the Storage subsystem
can be found in the Guardian file $SYSTEM.ZSPIDEF.ZSTOTAL.
Structure Definitions for ServerNet Wide Area Network (SWAN)
Below is the structure definition for the specific_info parameter when returned by a device
that uses ServerNet wide area network (SWAN) connectivity. The structure is defined by the wide
area network (WAN) subsystem. Devices for many HP communication subsystems, including
AM3270, ATP, CP6100, Envoy and Envoy ACP/XF, Expand, SNAX/XF and SNAX/APN, TR3271,
and X25AM support SWAN connectivity in NonStop S-series servers. (The structure definition
below applies only to the subsystems identified here.) Note that if an Expand or a SNAX device
does not use SWAN, null values are returned in this structure.
