Download Controller Firmware
Overview
This function downloads the controller firmware from the REMCS center or another storage system, and saves and registers the obtained controller firmware in the Bootup and Utility Device (BUD) of the CM. This function selects the download destination when downloading controller firmware, and the downloading method. Note that downloaded controller firmware can be registered automatically in the next storage system power-on.
- Settings for downloading controller firmware from the REMCS center and the downloading process are not performed in the following conditions: However, settings for downloading controller firmware from another storage system and the downloading process can be performed.
The Remote Support is not configured
The Remote Support is stopped
The Remote Support is under maintenance
Remote Support is operating, and the "Connection Type" is "Internet Connection (Mail only)", "P-P Connection (Mail only)", or "P-P Connection (VPN Connection Mail only)"
- The warning screen for downloading is displayed in the following conditions:
The controller firmware is already being downloaded
Downloading controller firmware is stopped
The controller firmware is being applied
The downloaded controller firmware is stored in the BUD of the CM. Only three generations of controller firmware can be stored in the BUD. If more than three generations of controller firmware have been downloaded, the oldest version will be overwritten, except the running firmware.
When downloading controller firmware from another storage system, perform "Setup Firmware Update from Peer Storage System" setting in advance to specify the storage system to obtain the controller firmware.
Controller firmware download may be stopped due to the line status, etc. The suspended controller firmware download will resume from where it was suspended, in the next download, which has been specified in the automatic download schedule. However, if the version of the controller firmware, which is stored in the download destination (the REMCS center or the source storage system), is newer than the version of controller firmware, which was restored after interruption, the newer version will be re-downloaded from the beginning.
If the download destination (REMCS Center or the source storage system) does not have the latest controller firmware to be received, the download process will not be executed.
When downloading controller firmware manually, and the download destination (REMCS center or the source storage system) has received connection requests, which exceed the number of simultaneous firmware distribution connections, the connecting destination status will become busy, and a message to that effect will be displayed. Wait a few minutes before resuming manually downloading controller firmware.
- If the [Download Firmware] is selected again while the controller firmware is being downloaded, the [Stop] button can be clicked to stop the download. Note that downloading cannot be stopped under the following conditions:
The controller firmware download was suspended, after download had been started
The controller firmware is being applied
- The unified firmware cannot be downloaded from the REMCS center.
- Refer to the [Apply Controller Firmware] function for details about how to apply the controller firmware in the following conditions:
The downloaded controller firmware is not automatically applied to the storage system
