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.
