An example of HP array card troubleshooting

The company uses HP gen8 machine , It's using p420i Array card , At the same time, at the other end of the system ,nagios Cooperation of monitoring system nrpe Script check_hpasm Regularly check Hardware Health .

Recently, in order to make the machine more exciting , Combined with the SSD Hard disk , Mechanical hard disk is only used for mass storage , While feeling speed and passion , Tragedy followed .

nagios Monitoring and alarming , hardware error ：

CRITICAL - da controller 1 in slot 1 needs attention, System: 'proliant dl3x0e gen8', S/N: 'CN74xxxxx', ROM: 'P73 12/20/2013' Performance Data:  pc_1=65 fan_5=27% fan_6=27% fan_7=27% fan_8=27% temp_1_ambient=23;42;42 temp_2_cpu#1=40;70;70 temp_4_memory_bd=24;87;87 temp_6_memory_bd=25;80;80 temp_7_memory_bd=26;80;80 temp_8_memory_bd=26;80;80 temp_9_memory_bd=25;80;80 temp_10_memory_bd=25;80;80 temp_11_memory_bd=26;80;80 temp_12_system_bd=35;60;60 temp_13_system_bd=44;105;105 temp_14_system_bd=33;95;95 temp_17_power_supply_bay=26;80;80 temp_18_power_supply_bay=25;80;80 temp_19_system_bd=25;110;110 temp_20_system_bd=21;110;110 temp_21_system_bd=24;110;110 temp_22_system_bd=26;110;110 temp_23_system_bd=21;65;65 temp_26_system_bd=35;100;100 temp_28_system_bd=28;90;90 temp_29_i/o_zone=85;100;100 temp_31_i/o_zone=32;80;80 temp_32_i/o_zone=25;80;80 temp_33_system_bd=32;80;80 temp_34_system_bd=30;80;80 temp_35_system_bd=30;80;80 temp_36_system_bd=31;80;80 temp_37_system_bd=29;80;80

Because the alarm content is very vague , Like a ***, Dare not put the machine into operation , The machine had to be transported back from the machine room for careful testing . It feels like a hardware failure , But instead Array card Even reinstalled N After the second operating system , Still report the same error . If not SSD, Only use ordinary hard disk , You can't report an error .

The final problem is HP Array Cary HP SSD smart path function , This function can speed up SSD Disk reading and writing , It's a bit mixed with hard disk , That is, as a cache of mechanical hard disk . But I'm sorry , If you use SSD If the operating system is installed on the hard disk , There will be errors reported above .
