Replacing a CompactFlash card in a single-controller system
running Data ONTAP 7.
x
The CompactFlash card stores a primary and secondary set of system files on it
(also called the
boot image ) that the system uses when it boots. To replace the
CompactFlash card, you must complete a specific sequence of procedures.
Notes:
1. You can use this procedure only with systems in a single-controller
configuration running Data ONTAP 7.
x .
2. In a single-controller system, the CompactFlash card is not a hot-swappable
component.
If your system is in an active/active configuration running Data ONTAP 7. x , use
the procedure in “Replacing a CompactFlash card in an active/active configuration
running Data ONTAP 7.
x ” on page 35.

Removing the CompactFlash card
1. Retrieve and save the system environment variables, if possible, by completing
the following substeps:
a.
Bring the system down to the LOADER prompt.
v
If the system is running, shut it down to the LOADER prompt by
rebooting it and pressing Ctrl-C when prompted by the system, and then
go to substep b.
v
If the system is at the LOADER prompt, go to substep b.
b. Display the system environment variables by entering the following
command from the LOADER prompt on the console:
printenv
c. Copy the environment variable values. You need these variable values for
the replacement CompactFlash card.
Attention: You do not need to retrieve the Fibre Channel port settings on a
single-controller system. Fibre Channel port settings are stored in the boot
environment and also on disk in the system root volume. When the system is
rebooted, Fibre Channel settings will be restored from the saved settings.
2.
Perform a clean system shutdown by entering the following command from the
system console:
halt
Attention: You must perform a clean shutdown to replace components inside
your system.
