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.

Command logging for audit

• “Logging other than raidcom command” (page 47)

• “Logging raidcom command” (page 49)

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.
