• /usr/local/tape/log/ems.lastmount.cmd

• /usr/local/tape/log/rescan.txt

• /usr/local/tape/log/SecureVTS.log

Note Though you can change the log level of these files, the log level is reset to the default

every time VTS is rebooted.

To view log files, the following commands are useful:

view logfile

To search the file

tail –f –n 35 logfile 

To list the file in real-time

grep –ni string logfile 

To search for a specific string

less logfile 

To search a file by paging through it

Compressed log files can be searched and viewed by using zgrep and zless.

EMS messages

The following table lists the messages that are generated by VTS if EMS is enabled and

configured. Here is an explanation of the information for each EMS message:

• The message text.

Some of the text in the messages and errors is parameterized, as indicated by the dollar

sign ($). In a real message, the parameterized text is replaced by a real value. For

example, the host system that initiated the request is represented in the message text as

$host, but an actual message displays the real hostname, such as DEV2.

• The severity of the message. The levels of severity include the following:

• Informational (Inform) — A normal operation has occurred.

• Warning — A suspicious operation, configuration, or user error has occurred. The

system or application can handle the error with no interruption and limited

degradation of service.

• Critical — A system or service error has occurred. The system can recover but a

momentary loss or permanent degradation of service may occur.

• The recommended action to take.
