3.5.2 Firmware Update Procedure
TFTP enables the administrator to download the new controller firmware from a TFTP server to the
controller. When using the TFTP command, a TFTP server must be running and a copy of the firmware
file image must be on the TFTP server. This command will “fail” the current controller and should not
be used during active I/O.
Follow these steps to update the firmware files.
1. Collect and save the output of the following commands before you update the firmware:
VERSION AV CACHE
DISK DISK LIST DUAL
HOST HOST STATUS LOG
LUN LUN CONFIG NETWORK
STATS STATS DELAY STATS TIER DELAY
TIER TIER CONFIG
2. Copy the new firmware file to your TFTP server.
3. Connect to the controller via Telnet or serial (CLI port).
4. Enter TFTP
5. You will be asked to confirm action (Figure 3–53). Enter y to continue.
