Upgrading Firmware
The MegaRAID Storage Manager software enables you to easily upgrade the controller firmware.
To avoid data loss because of dirty cache on the controller, the utility forces the virtual disks into Write Through mode
after a firmware upgrade. It is in this mode until the server reboots. In Write Through mode, the controller sends a data
transfer completion signal to the host when the disk subsystem has received all of the data in a transaction. This way,
in case of a power outage, the controller does not discard the dirty cache.
Follow these steps to upgrade the firmware:
1.
In the left panel of the MegaRAID Storage Manager window, click the icon of the controller you want to
upgrade.
2.
In the MegaRAID Storage Manager window, select Go To > Controller > Update Controller Firmware.
3.
Click Browse to locate the .rom update file, as shown in the following figure.
Figure 200 Update Controller Firmware Dialog
4.
After you locate the file, click Open.
The MegaRAID Storage Manager software displays the version of the existing firmware.
5.
When you are prompted to indicate whether you want to upgrade the firmware, click Yes.
A progress bar appears along with messages that indicate when an image opens and when an image downloads.
6.
After an image has been downloaded and if Online Firmware Update is supported on the controller, a
confirmation message box appears that asks for your confirmation.
