SCF Reference Manual for the Storage Subsystem (G06.28+, H06.05+, J06.03+)

The configured record size (in bytes) for the device.RecSize
Shows whether the IOP is configured to be in the STARTED or state when the system is loaded.StartState
SCSI Device Settings:
The maximum number of concurrent opens allowed by the IOP.MaxOpens
The maximum number of concurrent I/O operations the IOP can have outstanding; used by the
SCSI IOP to determine the size of allocated data-buffer area.
NumIO
The memory (in 1-kilobyte units) to be allocated for data structures by the IOP.StructAreaSize
The memory (in 1-kilobyte units) to be allocated for internal trace data by the IOP.TraceBufLen
The internal IOP trace level.TraceLevel
Path Information:
The name of the PMF CRU, IOMF CRU, or ServerNet/DA that controls the access path to the
device, determined by the location of the adapter in the system.
Adapter Name
The group, module, and slot number of the adapter.Adapter Location
(Group, Module,
Slot)
The logical unit number (LUN) of the device used by the IOP to select any additional devices that
are attached to the device.
LUN
The name of the SAC on the adapter, determined by the location of the adapter in the system.SAC Name
The subdevice number of the SAC on the adapter which determines which SCSI bus accesses the
device.
SAC Number
For Open SCSI devices, the SCSI ID that the IOP uses to access the device.SCSI ID /
Portname
For Open SCSI Fibre Channel devices, the worldwide name (WWN) that the IOP uses to access
the device.
