This switch is not for use with Storage Integration for IBM Tivoli or Storage Integration for EMC Centera.
With this switch applied, the log file is not deleted. The log file will be appended with information using this switch. The date/time entry is stamped when DDS is started or stopped.
You can also specify that a set number of archived logs be kept. A new log is created each time DDS is restarted. To accomplish this, set the -keeplog switch equal to the number of logs you want to retain. For example, if you want to allow 5 logs to be kept at a time, you would apply -keeplog=5. DDS will always write to the log.txt file. When DDS is restarted, the old log.txt file is renamed to log_1.txt. The next restart will create the next log as archive log_2.txt, and so on, until the maximum number is reached. Once the maximum number of logs is reached, the log_1.txt file is dropped and each subsequent archived log is renamed, such that log_2.txt becomes log_1.txt, and so on.
If you change the number you specify to a number smaller than the current setting. The logs that have numbers surpassing the new maximum will be left untouched.
