GAMSETSZ Command Line
E-2 Disk Array Controller Software Kit User’s Manual
The Drive Size Limits function provides a resolution to this problem. You
can manually set the maximum, usable size of particular disk drives from
particular vendors such that they are equivalent across vendors’ drives.
For example, Vendor A’s 4.01 GB drive can be manually set to 4 GB.
Likewise, Vendor B’s 4.12 GB drives can also be manually set to 4 GB. For
GAM, the capacities of the drives would be considered equivalent and no
complications should arise when using hot spares or when mixing drives
from different vendors in a single logical group.
GAMSETSZ Command Line
The Mylex Drive Size Limit function is installed during normal GAM Server
installation under supported operating systems. During installation of GAM
Server, there is an instruction to modify the GAMEVENT and GAMEVLOG
command lines in the system startup file to specify the IP addresses of client
systems and the path and name of the message log file. Within this same
startup file, the gamsetsz command line (enabled by default to use settings
stored in the file MYLEXDRV.SIZ) is found at the bottom of the section
called “DRIVE SIZE LIMIT.”
The following gamsetsz command line is installed during GAM Server
installation:
[path]gamsetsz -f [path]mylexdrv.siz &
where:
[path] : is the directory path to the GAMSETSZ utility file;
& : indicates that you may include additional drive size settings
filenames after the ‘&’ (perhaps from a drive vendor) which also define
specific drive size information.
☛
Note
If you have particular SIZ files available from one or
more drive vendors, add the filename(s) to the end of
the gamsetsz command line. Refer to the next section
for information on modifying the contents of the
Mylex-supplied SIZ file (MYLEXDRV.SIZ).
