Controller Firmware Upgrade Features

The following firmware upgrade features apply to the controller firmware:
Redundant Controller Rolling Firmware Upgrade
I
When download is performed on a dual-controller system, firmware is flashed
onto both controllers without interrupting host I/O. When the download process
is complete, the primary controller resets and lets the secondary controller take
over the service temporarily. When the primary controller comes back on-line, the
secondary controller hands over the workload and then resets itself so the new
firmware can take effect. This rolling upgrade is automatically performed by
controller firmware, and the user's intervention is not necessary.
Automatically Synchronized Controller Firmware Versions
I
A controller that replaces a failed unit in a dual-controller system is often running
a newer release of firmware version. To maintain compatibility, the surviving
primary controller automatically updates the firmware running on the
replacement secondary controller to the firmware version of the primary
controller.
Note – When you upgrade your firmware, the format(1M) command still shows
the earlier revision level. To correct this you need to update the drive label, using the
autoconfigure option (option 0) of the format(1M) command. When you select
label, the drive is labelled with the updated firmware version.
Upgrading Firmware Using the Serial Port Connections (from Windows hosts)
I
The firmware can be downloaded to the RAID controller by using an ANSI/VT-
100 compatible emulation program. The emulation program must support the
ZMODEM file transfer protocol. Emulation programs such as HyperTerminal,
Telix, and PROCOMM Plus can perform the firmware upgrade.
