Using the MYLEXDRV.SIZ File
The gamsetsz command line makes reference to the MYLEXDRV.SIZ file.
This is a Mylex-supplied text file containing instructions for defining drive
size limits. It is also the text file in which you actually store the drive size
information that will be read by GAMSETSZ and used in GAM
configurations.
☛
Note
We recommend that you print and/or view online the
MYLEXDRV.SIZ file at your earliest convenience.
The structure of a drive size limit data line is
somewhat complex, and advance study of the byte
definitions can be helpful.
A summary of the byte definitions is provided in the
next section of this appendix.
MYLEXDRV.SIZ Byte Definitions
The MYLEXDRV.SIZ file contains detailed byte definitions for construction
of data lines to be read by GAMSETSZ. Constructing a valid data line
consists of providing the requested information correctly at each of the
appropriate byte positions in the data line.
Use only what is referred to as the “New Format.”
The basic structure of a New Format data line is as follows:
[+/-][vendor ID][product ID][revision] [capacity][units][comments]
Table E-1 beginning on the next page displays the following information:
• The byte position range for a data item (such as 0..0, 1..28)
• The number of bytes used for the data item
• Valid values for the data item
• Brief description of the data item.
