•
Has no pending I/Os
•
Has never had more than one pending I/O at a time (High Pending I/O)
•
Is currently being used by one requester (Opens)
LDev shows the logical device number for the Open SCSI device. This
number is arbitrarily assigned to a device when the device is
configured and every time the system is loaded.
Primary shows the current SCF state for the primary access path to the
device (see Table 6-1 on page 6-1).
Backup shows the current SCF state for the backup access path to the
device (see Table 6-1
on page 6-1).
Primary PID shows the processor number and PIN of the current primary
Open SCSI I/O process.
Backup PID shows the processor number and PIN of the current backup Open
SCSI I/O process.
* indicates the current path to the Open SCSI device.
