AST RESEARCH TECHNICAL BULLETIN TB-0021 6-22-84
USING A TALLGRASS HARDFILE AS THE PC-NET FILE SERVER
A Tallgrass HardFile running with Tallgrass software release 4.18
or later is fully compatible with AST-PCnet and AST-PCnet II.
However, for proper operation with the network, please note the
following.
1. The "Duplicate Directory", "Cache Memory", "Verify Read
After Write", and "Landing Zone" options must be turned
off (disabled).
2. Any time you change the "Duplicate Directory",
"Allocation Unit Size (AU)", or "Directory Size"
parameters in TGSYS, you must also initialize the
affected directory or directories on the HardFile. This
is done with the "D" or "F" commands in the Tallgrass
program called UTILITY. Since initializing the
directory will cause you to lose all the data on that
volume, these options should be used with great caution.
3. Whenever you change the "Duplicate Directory",
"Allocation Unit Size (AU)", or "Directory Size"
parameters in TGSYS, followed by the "D" or "F" options
in UTILITY, you must run SPCINST followed by UPCINST on
all affected networked PCs.
Failure to observe these instructions may cause the uPCs to
be unable to properly read the Tallgrass directory. For
example, a "DIR" command from the uPC to the sPC's Tallgrass
drive may show missing files, extra files, or no files at
all, while the same "DIR" command entered at the sPC returns
the proper directory listing. Another symptom of this
problem is when a "CHKDSK" command issued to a shared volume
returns different information on the uPC compared to the
same command issued at the sPC.
