Dell PowerVault 221S Updating the Enclosure Management Module Firmware - Page 13

FILE LOCATION: S:\systems\Zappa\Ts\EMM Firmware_N8865\N8865eb0.fm Updating the Storage System in Split-Bus Mode For storage systems in split-bus mode, updating the firmware to one EMM does not automatically update the other EMM. Each EMM must be updated from the host system that is attached to it. Array Manager displays the correct firmware version for the EMM to which it is connected, but may continue to report the old firmware version on the other EMM. This situation is corrected by restarting the PowerVault storage system. Using Earlier Versions of Array Manager If your system is configured with Array Manager version 3.1.1 or earlier and the split-bus module is in the cluster mode, the EMM firmware can only be upgraded on the primary EMM. To update both EMMs, download the firmware from each cluster node to the individual EMMs on the storage system. If you are upgrading the firmware using Array Manager version 3.1.1 or earlier and the storage system is configured with one EMM in joined-bus mode and one SCSI terminator card, an error message appears on your screen. This condition is normal. If the storage system cooling fans return to their normal operating speed after you update the firmware, the firmware update was successful. To verify the firmware update, stop and then restart the Disk Management Service. When completed, ensure that the firmware version in the enclosure properties has changed to the updated version. Updating the Storage System Without Array Manager If Array Manager is not installed on your host system, you can temporarily attach the storage system to another system that is running Array Manager and flash the EMM firmware from this system. Alternately, you can contact Dell Support to replace your EMM modules. DELL CONFIDENTIAL - PRELIMINARY 10/26/04 - FOR PROOF ONLY Updating the Enclosure Management Module Firmware 13
