Firmware Updates
Fast and easy download of new versions of controller and disk firmware is possible using the
SANnet II 200 SCSI array management suite. The Dot Hill CLI and SANscape both support
controller updates over in-band SCSI connections and out-of-band Ethernet connections.
SANscape provides updates for disks over in-band SCSI connections.
When firmware updating is performed on a redundant controller array, firmware is loaded onto
both controllers without interrupting operations. When the download process is complete, the
primary controller will reset and let the secondary controller take over all services temporarily.
When the primary controller comes back on-line, the secondary controller will transfer over all
operations and reset. Once the secondary controller comes back online, the primary controller
restores the redundant controller configuration. The redundant controllers automatically perform
the upgrade process.
A controller that replaces a failed unit in a dual-controller system might be running a different
release of firmware version. To eliminate the potential for issues, the existing array controller
automatically updates the firmware of the replacement controller to match the existing
controller’s firmware.
