Explanation of Fields
I/O Process Information:
* indicates an attribute whose value you can change by using
an ALTER SCSI command.
BackupCpu the processor number of the backup IOP.
HighPin shows whether the IOP can run at a high PIN (ON) or a low
PIN (OFF). The PIN is the process identification number.
PrimaryCpu the processor number of the primary IOP.
Program the object file name of the IOP.
RecSize the configured record size (in number of words) for the
device.
StartState shows whether the IOP is configured to be in the STARTED
or state when the system is loaded.
SCSI Device Settings:
MaxOpens the maximum number of concurrent opens allowed by the
IOP.
NumIO 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.
StructAreaSize the memory (in 1-kilobyte units) to be allocated for data
structures by the IOP.
TraceBufLen the memory (in 1-kilobyte units) to be allocated for internal
trace data by the IOP.
TraceLevel the internal IOP trace level.
Path Information:
Adapter Name 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 Location
(Group, Module, Slot)
the group, module, and slot number of the adapter.
LUN the logical unit number (LUN) of the device used by the IOP
to select any additional devices that are attached to the
device.
