You can specify to update all disks or only specific disks. If you specify to update all disks and the system contains more than
one type of disk, the update will be attempted on all disks in the system. The update will only succeed for disks whose type
matches the file, and will fail for disks of other types.
Prepare to update disk-drive firmware
1. Follow the best practices in Best practices for firmware update.
2. Obtain the appropriate firmware file and download it to your computer or network.
3. Stop I/O to the storage system. During the update all volumes will be temporarily inaccessible to hosts. If I/O is not stopped,
mapped hosts will report I/O errors. Volume access is restored after the update completes.
Update disk-drive firmware
1. Perform one of the following:
● In the banner, click the system panel and select Update Firmware.
● In the System topic, select Action > Update Firmware.
The Update Firmware panel opens.
2. Select the Update Disk Drives tab. This tab shows information about each disk drive in the system.
3. Select the disk drives to update.
4. Click File and select the firmware file to install.
5. Click OK.
CAUTION:
Do not power cycle enclosures or restart a controller during the firmware update. If the update
is interrupted or there is a power failure, the disk drive might become inoperative. If this occurs, contact
technical support.
It typically takes several minutes for the firmware to load. Wait for a message that the update has completed.
6. Verify that each disk drive has the new firmware revision.
Using the activity progress interface
The activity progress interface reports whether a firmware update or partner firmware update operation is active and shows the
progress through each step of the operation. In addition, when the update operation completes, status is presented indicating
either the successful completion, or an error indication if the operation failed.
Use the activity progress interface
1. Enable the Activity Progress Monitor service. See Enable or disable system-management settings.
2. In a new tab in your web browser, enter the URL for the form: http://controller-address:8081/cgi-bin/
content.cgi?mc=MC-identifier&refresh=true where:
●
controller-address
– Required parameter that specifies the IP address of a controller network port.
● mc=
MC-identifier
– Optional parameter that specifies the controller for which to report progress/status:
○ mc=A – Shows output for controller A only.
○ mc=B – Shows output for controller B only.
○ mc=both – Shows output for both controllers.
○ mc=self – Shows output for the controller whose IP address is specified.
● refresh=true – Optional parameter that causes automatic refresh of the displayed output every second. This will
continue until either:
○ The parameter is removed.
○ The controller whose IP address is specified is restarted and communication is lost.
When activity is in progress, the interface will display an MC-specific Activity Progress table with the following properties
and values.
