9.1 Single Controller Upgrade
A Single Controller Upgrade is synonymous with a Shutdown Upgrade. A
Shutdown Upgrade is one in which the storage device is taken off-line for the
period of time that the software is being installed. Use the following procedure
to upgrade the HSOF software in a non-redundant (single) controller:
1.
Halt all host I/O activity to the controller and prepare the host system for a
controller shutdown using the appropriate procedures for your operating
system.
2.
Establish a local connection to the controller through the maintenance port
of the controller.
3.
Shutdown the controller with the following command:
SHUTDOWN THIS_CONTROLLER
CAUTION
Failure to shut down the controller in this step could result in
problems with RAIDsets and cache when the controller is reset.
CAUTION
Before continuing, wait until the Reset button on the controller
stops flashing (lit continuously). This indicates that unwritten
data is flushed from the cache module.
4. Remove the PCMCIA program card ESD cover from the controller.
5.
While pressing and holding the controller Reset button, press the program
card eject button to eject the program card from the controller. Release the
button after the card is ejected.
NOTE
The controller will initialize and the Reset button will flash at
an approximate once per second rate when ready for operation.
6. Press and hold the Reset button while inserting the new program card.
Release the button after the new card is inserted.
