Extreme TAC personnel can check systems to see if a firmware update is required. While logged in as root
, execute the following command:
sw0:FID128:root> cat /proc/hv_console | grep Mfr
This will return the eUSB controller vendor and firmware type, which will look like this:
Mfr=Hyperstone GmbH, Product=U8 HyMap FlashDisk B, SerialNumber=00000900xxxx
If the manufacturer is Hyperstone
and the product field contains “HyMap
”, the device is the type that requires the updated firmware. If either of those fields is different, the device does NOT require updating. If both fields match, the next step is to check if the firmware has already been updated. To do that, execute the following command (still as root):
sw0:FID128:root> bootenv | grep ssd_fw_version
ssd_fw_version=161014u8 2.01 INT
If nothing is returned, the drive has not been updated. It is only necessary to update the firmware if both the vendor and firmware type match and it has not already been updated.
Extreme has provided updated firmware for the eUSB device that corrects this defect, and has developed a utility to apply the firmware update in the field. This update process should be done by trained Extreme TAC personnel. Applying the update is disruptive – traffic will stop, and the system needs to be rebooted at the completion of the process. For that reason, Extreme recommends that the update be applied during a maintenance window where network traffic won’t be affected. System data on the eUSB (including configuration information) is not affected by this update and the system can be returned to service after the update has been applied.
Extreme will also provide the updated firmware for the eUSB device as part of a future NOS upgrade (v7.2.0c and v7.4
). Upgrading to this version will automatically upgrade the eUSB firmware.
For customers who have experienced this failure on one or more of their VDX6940 systems, or where the failure of a VDX6940 is disruptive to their network, Extreme recommends proactively updating affected VDX6940s in the customer network. For customers who cannot tolerate the disruption of the upgrade process, Extreme recommends they wait for the delivery of the updated firmware as part of NOS.
