As a last resort before replacing a failing hard disk
drive
Note
For information about backing up all of the files, see
the operating-system documentation.
Starting the Low-Level Format
Attention
The low-level format erases
all data and programs.
1. If the hard disk drive is working, make a backup copy
of all the files and programs on the hard disk.
2. Select Format Disk; then, follow the instructions on
the screen.
Note
Hard disks normally contain more tracks than
their stated capacity (to allow for defective
tracks). A message appears on the screen if the
defect limit is reached. If this happens, have the
system serviced.
3. To install an operating system after the hard disk is
formatted, follow the instructions in the ServerGuide
package that comes with the server.
Security Options
Security features can help to protect the server data and
programs from unauthorized access and use, and help to
physically protect the server from theft and tampering.
To control access to the information in the server
databases, you can implement security measures through
the system configuration programs. These features
include defining two levels of password protection,
restricting diskette access, and defining a system owner's
name. Implementing these security measures helps you to
ensure the integrity of the data and programs that are
stored in your server. See “System Security” on page 21
for details.
To prevent writing to a diskette in a diskette drive, set the
diskette write-protect switch, as described in “Diskette
Write-Protect Switch” on page 98.
To control access to other hardware components in your
server, you can install several types of optional devices.
These options include:
U-bolt
Security cable
Padlock
To do this, see “U-Bolt” on page 101.
