Log files

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

File Name

Description

 

 

 

 

/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.

 

 

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:

#ls /olds/chkDisks

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

#cp /cms/rdonly/olds_install/chkDisks /olds

#chmod +x /olds/chkDisks

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

#/olds/chkDisks
