HP Dl380 Gen7 random reboots

Hello. 

Have random reboot (period 2-60 days) problem with 3 from 3 HP DL380 Gen7 servers in one datacenter. Have a server of other manufacturer near HP servers and it works stable.

All servers have 2 power supplies and in logs (ipmitool sel list) i see only messages about power failure on one of supplies:

a | 09/30/2017 | 14:45:48 | Power Supply #0x04 | Failure detected | Asserted
b | 02/11/2018 | 10:41:59 | Power Supply #0x04 | Failure detected | Asserted

sdr -v shows active power redundancy :

Sensor ID              : Power Supplies (0x5)
 Entity ID             : 10.3 (Power Supply)
 Sensor Type (Discrete): Power Supply (0x08)
 Sensor Reading        : 0h
 Event Message Control : Entire Sensor Only
 States Asserted       : Redundancy State
                         [Fully Redundant]
 Assertions Enabled    : Redundancy State
                         [Non-Redundant: Sufficient from Redundant]
                         [Non-Redundant: Sufficient from Insufficient]
                         [Non-Redundant: Insufficient Resources]
 Deassertions Enabled  : Redundancy State
                         [Redundancy Lost]
 OEM                   : 0

Why I see a reboot if only one power supply fails?

hi,

-Please check using power Advisor utility to check how many power supply required for your Server. Refer

-Also please check in RBSU if Appropriate Redundancy option is Selected.

>> Please check using power Advisor utility to check how many power supply required for your Server. Refer

Utility is for WIndows and I run Linux with no X11 desktop, so can't use it.
Do you mean that this server could use two supplies only for balancing load and not for keeping server alive on one of supplies if other failed?

Checked web-interface and redundancy is OK (see screenshot)
