Lewan has received reports from multiple customers where after applying Proliant Support Pack (PSP) 8.20 to a Windows server the servers are spontaneously rebooting.
One possible cause for this is an issue with the version of the “HP ProLiant iLO 2 Management Controller Driver for Windows Server” which was included in PSP 8.20. PSP 8.20 includes version 1.9.0 of this driver.
A specific fix for a false ASR issue is included in version 1.11.0 of the same driver.
If you are experiencing this issue, you will see ASR related events logged by the system management; these logs can be viewed via the System Management homepage.
To correct this issue, either apply the updated driver, or disable the ASR feature via the System Management Hompage. It’s probably also a good idea to update the iLO firmware itself.
PSP 8.25 includes a newer version of the driver.
ASR is the Automatic System Recovery feature of the HP iLO which attempts to detect a hung or crashed server and reset it.
