You probably need to find RXSCSIFN SAMPMOD and copy it as RXUSERFN
MODULE; SCSIDISC uses it.
From SCSIDISC HELPCMS:
SETUP - Located on MAINT 194 or 2C2 disk
Find SCSIDISC SAMPEXEC - Copy to SCSIDISC EXEC

prefomance of SCSI on a lun was superior to that of sharefile it would

FYI, SCSIDISC requires a LUN zero exist and be accessible in each
storage controller to be scanned.
Assuming non-NPIV, If one's using IBM San Volume Controller then
consider having the very first LUN (LUN ) that each of its I/O
Groups maps to your host (mainframe) be a minimal size LUN
on some occasions SCSIDISC will report LUN_SIZE_(bytes) as a negative
number. Seen that only for large LUNs.
On other occasions some of the fields, LUN_SIZE too, will be reported as
