4.13.3 Horcctl Command
The HORCM and Hitachi TrueCopy software have logs that identify the cause of software
and/or hardware errors as well as a tracing function for investigating such errors. The
location of the log files depends on the user’s command execution environment and the
HORC Manager’s execution environment. The command trace file and core file reside
together under the directory specified in the HORC Manager’s execution environment. See
Appendix A for log file and log directory information.
The Hitachi TrueCopy horcctl command can be used for both maintenance and
troubleshooting. The horcctl command allows you to change and display the internal trace
control parameters (e.g., level, type, buffer size) of the HORC Manager and/or Hitachi
TrueCopy commands. If a new value for a parameter is not specified, the current trace
control parameter is displayed. Table 4.37 lists and describes the horcctl command
parameters.
Caution: Do not change the trace level unless directed to do so by a Hitachi Data Systems
representative. Level 4 is the normal trace level setting. Levels 0-3 are for troubleshooting.
Setting a trace level other than 4 may impact problem resolution. If you request a change of
the trace level using the
horcctl -l <level> command, a warning message is displayed, and
this command enters interactive mode.
