MODIFYING PASSWORDS
Passwords can be changed by logging in and using the passwd command.
They can be added when logged in as root by entering the passwd command with the new User-id as the first
parameter.
They can be deleted by coping the /etc/passwd file to diskette, using an editor on an MS-DOS PC to remove the
line containing the user-id, copying the file back to the Data Advantage and rebooting the Data Advantage.
HARD DISK CLEANUP
The logs in the /activity directory should be deleted periodically to prevent the disk from filling up. The amount
of data written to the log files can be reduced by limiting the types of messages logged. In most cases,
information messages should be disabled unless maintenance work is being performed on the system. The
command “log -m warn” will enable error and warning messages and disable informational messages. The “df”
command displays the amount of free space on the hard disk.
LOADING NEW SOFTWARE RELEASES
1.
Insert the Loader diskette into the floppy drive.
2.
Enter "reboot -h" from the Diagnostic Terminal, press the reset button on the CAP Board, or turn on the
Data Advantage VME chassis.
3.
Each time Data Advantage prompts for a diskette, insert an Application diskette or Configuration
Working diskette. When all disks have been loaded, press return with no diskette inserted.
Do not press the reset button on the CAP Board while the hard disk is active. Doing so may lock up the drive, requiring
power to be cycled on the Data Advantage VME Chassis.
