We are now dealing with file in excess of 54 gig since they can not be
contained on a single mod54 minidisk we have been writing to sharefile but
have found the perforamce to be dreadfull. Does anyone have performance
numbers using SCSI devices on native z/VM, compared to sharefile. If the
prefomance of SCSI on a lun was superior to that of sharefile it would
solve a major problem here.

You probably need to find RXSCSIFN SAMPMOD and copy it as RXUSERFN MODULE;
SCSIDISC uses it.

SETUP - Located on MAINT 194 or 2C2 disk
Find SCSIDISC SAMPEXEC - Copy to SCSIDISC EXEC
Find RXSCSIFN SAMPMOD - Copy to RXUSERFN MODULE

SCSIDISC (the SCSI Discovery Tool) is a sample exec which provides target
port and LUN information so one can "discover" the LUN topology which
hangs off a System z FCP Subchannel. The help file for the tool (SCSIDISC
SAMPHELP) indicates that it is "Located on MAINT 194 or 2C2 disk".
Regards, Steve.
I copied SCSIDISC SAMPEXEC to SCSIDISC EXEC, but when I run it I get -
DMSRTL2103E Error in compiled CMS system Rexx file; additional information:
4300
43 SCSIDISC EXEC 587
