3.2.4.3.2 Performing the Upgrade
Warning: It is extremely important that the power not be turned off to either the server
or the DSE4XM chassis during a firmware upgrade, nor should the cable be disconnected.
Power or connectivity loss during a firmware upgrade could cause device failure. Consider
adding a UPS to the system prior to performing a firmware upgrade to prevent this from
happening.
Caution: You should back up the data on the ioDrive prior to any upgrade as a precaution.
Note: You must upgrade the ioDrive driver if you upgrade the device firmware.
Note: To correctly perform the firmware upgrade, you must power the system,
including the DSE4XM chassis, all the way down and bring it all the way back up. This
shutdown and restart is required for the upgrade to complete on the ioDrive.
Note: A firmware upgrade may in some instances require a low-level format. Refer to
the release notes for specific details.
Note: Upgrading the firmware may take several minutes. The update command
displays a progress bar to indicate the pace of the upgrade.
Typically, you use the ioManager console to perform firmware upgrades. You can also
perform the upgrade using the fio-update-iodrive command line utility.
To upgrade the firmware on the ioDrive using fio-update-iodrive:
1. Open a Command Prompt. Navigate to the Program Files\Fusion-io\utils directory.
2. Run the Detach command for your device at the Command Prompt. For example:
fio-detach /dev/fct0
detaches the ioDrive labeled “fct0”. You need to specify the name of your drive you
want to detach. (Each ioDrive is labeled /dev/fct# where # is its PCIe bus number.
Use fio-status at a Command Prompt to view this number.)
The fio-detach command will show a progress bar and percentage as it completes
the operation.
3. Type the following command at the Command Prompt:
fio-update-iodrive <path>iodrive_version.fff
where <path> is the location of the ioDrive firmware. The default path is Program
Files\Fusion-io\firmware. The version is the numerical version of the drive.
Note: All three of the ioDrive slot LED indicators will light during the update pro-
cess.
4. Completely power down the server and the DSE4XM chassis. Turn off the AC
power to the DSE4XM chassis, and turn it back on again. Restart the server, which
