RAID Manager trace files
The command trace file is used for maintenance aiming at troubleshooting. It is not created normally.
If a cause of an error cannot be identified using the log file, the environment variables or trace
control commands with trace control parameters are issued to start tracing and the trace file is
created. The trace control parameters include trace level, file size, mode, etc. More detailed tracing
is enabled by increasing the trace level. Tracing is made in wraparound within the range of the
file size. HORCM makes the trace file according to the trace level specified in the HORCM startup
shell script set to activate the HORCM.
RAID Manager trace control command
The trace control command (one of the HORCM control commands) sets or changes the trace
control parameters. This command is used for troubleshooting and maintenance. If no trace control
parameters can be specified using the environment variables in your command execution
environment, it is possible to change the trace control parameters into the global parameters using
this command.
Table 9 (page 47) lists and describes the parameters of the trace control command.

Logging other than raidcom command
This section explains the logging other than the raidcom command described in “Logging raidcom
command” (page 49) .
RAID Manager supports command logging, this logging function cannot be used for auditing the
script issuing the command. Thus, RAID Manager supports the function logging the result of the
command executions by expanding the current logging.
This function has the following control parameters.
•
$HORCC_LOGSZ variable
This variable is used to specify a maximum size (in units of KB) and normal logging for the
current command. /HORCM/log*/horcc_HOST.log file is moved to
/HORCM/log*/horcc_HOST.oldlog file when reaching in the specified maximum size. If this
variable is not specified or specified as 0, it is same as the current logging for only command
error.
This variable is able to define to the environment variable and/or horcc_HOST.conf as
discussed below.
