Guardian Procedure Calls Reference Manual

Z^SUBSYS^MANAGER
is the name of the Guardian subsystem manager process.
Z^PRIMARY^PHANDLE
is the process handle of the primary I/O subsystem that owns the device.
Z^BACKUP^PHANDLE
is the process handle of the backup I/O subsystem that owns the device.
Z^RESERVED^1
is reserved.
Structure Definitions for specificinfo
The specificinfo parameter contains information passed back from the subsystem called by
CONFIG_GETINFO_BYNAME (and the other CONFIG_GETINFO procedures). The structure of
this parameter is different depending on which subsystem is called. The
CONFIG_GETINFO_BYNAME procedure supports these subsystems:
• Storage subsystem
• ServerNet Lan Subsystem Access (SLSA) Subsystem
• ServerNet Wide Area Network (SWAN)
Structure Definitions for Storage Subsystem
The structure returned by the storage subsystem in the specificinfo parameter of the reply
consists of a header field followed by a number of path info fields.
The structure is specific to the type of device being described; for example, the information for a
magnetic disk or SCSI-IOP device contains SCSI-specific information, and the path for a tape device
contains tape-specific information, and so on.
The structure for magnetic disk and SCSI-IOP devices is defined in TAL in file ZSTOTAL as follows:
STRUCT SCSI^DEVICE^INFO^DEF (*) FIELDALIGN (SHARED2);

STRUCT SPECIFIC^HDR;

INT VERSION;
INT MAX^NUM^PATHS;
