I recently toke over a role and handled this server dl360 g7. It has 2 power supplies all are ok. 1 degraded fan and others are all green. Installed with VMware esxi and and 3 vm installed. The server will run for few hours (not consistent) sometime 3 to 4 hours sometime its last longer but less than 12 hours it became unresponsive. The health Led turns blinking red but the power remains green. I tried to press and hold the power button to shutdown but it wont, instead the health Led will turns amber for few seconds, fans will speed up a bit then turns to red again and nothing happen. The only way to turn it on is to unplug both power cord and plug it again. Once on, it will continue accessible but after few hours again the problem repeat.I was wondering if the degraded fan causes this instance? Or there is more something bigger problem. Appreciate any help. Thanks
A single broken fan should never cause this kind of "critical" (that's what health light = red means) problem. Your server has probably six hot swappable fans that create a wind tunnel through the chassis, so if five are really up then you should be fine IMO.
You need to get a handle on what component is failing/has failed/is getting too hot. Use HP Insight Diagnostics software to look at your hardware in detail whether it is running or turned off.
If using diagnostics does not highlight an obvious problem for you, your HP Proliant also has a non-maskable interrupt function. There's a pair of pins on the server's mobo which, when shorted, will initiate a crash dump for you to review for problem details.
The pin location should be shown on the big label under the top cover of the server, but be sure to carefully read HP's documentation first.
Log onto the ILO3 interface and it will tell you exactly what the server's health history and specific problems are within the IML log. This is the best option for a VMware installation since you likely don't have the HP-specific ESXi build running on your system.
You should also replace the failed fan.
