A disk-mirrored system contains the following system log files:

If a log seems to indicate a problem, it may take an experienced 
troubleshooter to determine the nature of the problem.

The logs are checked each night by the chkDisks crontab, which is able 
to determine whether any potential or actual drive problems have been 
logged. The results of the determination are logged to 

/olds/elog and 

mailed to the 

root user.

If chkDisks is not running each night, verify that it is available in the 

/olds 

directory by entering the following command:

If the file is not found, load the CMS CD into the CD-ROM drive and enter 
the following commands:

To test chkDisks, simply execute it by entering the following command:

/var/adm/messages

Contains all console error messages, including 
hardware messages. (For an example of how 
to use this log to detect a bad disk drive, see 
Replacing Faulty Disks” in Chapter 3.)

/olds/elog

Contains 

olds error messages. Most messages 

are logged when setting up the system or when 
making changes to the disk setup.
