Maintenance log and tracing functions

Hitachi AMS 2000 Family Command Control Interface (CCI) Reference Guide

Windows

In the same way as Solaris, the command log is stored in the command log 

file in the start log directory, shown in 

Figure 3-1

. The error log is stored in 

the HORCM error log file in the error log directory, also shown in 

Figure 3-

1

.The following are locations for storing the command log and error log in 

case the directories are not specified using the environmental variable, 

HORCC_LOG.

Command log: \HORCM\logINS\horcc_HOST_log.txt

Error log: \HORCM\logINS\curlog\horcmlog_HOST\horcm_log.txt

• INS is an instance number.
• HOST is a host name of the computer concerned.
