log/curlog.
$HORCM_TRCSZ:
Specifies the size of the HORCM trace file in kB,
default = 1 MB. The trace file size cannot be changed using the horcctl
command.
$HORCM_TRCLVL:
Specifies the HORCM trace level (0 - 15), default
= 4. If a negative value is specified, trace mode is canceled. The trace
level can be changed using the horcctl
-c -l command.
$HORCM_TRCBUF: Specifies the HORCM trace mode. If this variable
is specified, data is written in the trace file in the non-buffer mode. If
not, data is written in the buffer mode. The trace mode can be changed
using the horcctl
-c -b command.
$HORCM_TRCUENV: Specifies whether or not to succeed the trace
control parameters (TRCLVL and TRCBUF) as they are when a
command is issued. When this variable is specified, the HORCM default
trace control parameters are used to the trace control parameters of
HORCM as global parameters. If not, the default trace control
parameters for HORCM commands are used and tracing level = 4,
trace mode = buffer mode.
$HORCMFCTBL:
Changes the fibre address conversion table number,
used when the target ID indicated by the raidscan command is
different than the TID on the system.


2000 systems: \WINNT\horcmperm.conf or
\WINNT\horcmperm*.conf 
For Windows Server systems: \WINDOWS\horcmperm.conf or

When the variable is set HORCMPERM = MGFNOINST, the built-in
command will not execute. Set this variable when you want to execute
any command from you shell script.
