Event ID: 57 Source: hpqmgmt

Sensor 9b is missing. Reading Flags = 40
From a support forum: We got this error on a DL180 G6 server. We have already tried to update the drivers (for HP ProLiant 100-Series Management Controller Driver for Windows 2003/2008 -- version :, BIOS version : 2009.07.28) but it didn't help. Apparently, this is a issue with the Lights-Out Management driver however the new driver release has not yet fixed the issue. As a workaround we could disable the lights out card, however this would not be desirable if we need to use the Lights Out feature.

Several HP support forum posts mentioned that a driver update (a 2009 update for DL180 servers) fixed the issue so if the problem is a recent one, on a different type of server, most probably this is a bug in the HP drivers that has to be reported to the HP engineers can include the fix in the next update.
Another version of the event description is "Unable to initialize the BMC Watchdog Timer. Feature Disabled." On HP ProLiant 100-series G6 and DL165 G7, the proposed fixed (by HP) is to disable the IPMI Watchog Timer by doing the following change on the server's BIOS:
- Go to the server's BIOS (press F10 during POST).
- Go to the Advanced section
- Go to the IPMI or IPMI Configuration option.
- Find the option called IPMI Watchog Timer (NOTE: You may find the option inside another submenu called Watchdog Configuration)
- By default, the option is Reset System ; change it to Disabled.

The warning is generated, because this driver does not provide support for ASR under Windows platforms as outlined in the release note of this driver.
