server HP ML350 G5 tidak bisa booting [red internal System health LED]

Bismillah...
kemarin salah satu server kami (server HP Ml350 G5) tidak bisa booting setelah lama tidak di hidupkan , salah satu indikator led menyala dengan warna mearah berkedip (flashing) ,

berikut informasi  HP ProLiant ML370 G5 Server - LEDs and Buttons

Systems Insight Display LEDs

To view a quick reference for component identification and status, access the Systems Insight Display.

Item	Description	Status
1	Primary power supply LED	Amber = Failure Off = Normal
2	Redundant power supply LED	Amber = Failure Off = Normal
3	Online spare memory LED	Green = Protection enabled Amber = Memory failure occurred Flashing amber = Memory configuration error Off = No protection
4	Mirrored memory LED	Green = Protection enabled Amber = Memory failure occurred Flashing amber = Memory configuration error Off = No protection
5	FBDIMM LEDs* (memory board 1)	Amber = Failure Off = Normal
6	FBDIMM LEDs* (memory board 2)	Amber = Failure Off = Normal
7	Processor 1 LED	Amber = Failure Off = Normal
8	PPM 1 LED	Amber = Failure Off = Normal
9	Processor 2 LED	Amber = Failure Off = Normal
10	PPM 2 LED	Amber = Failure Off = Normal
11	Hot-plug fan LEDs	Amber = Failure or fan is not installed Off = Normal
12	Internal system health LED	Green = Normal (system on) Amber = System health is degraded Red = System health is critical Off = Normal (system off)
13	External system health LED (power supply)	Green = Normal (system on) Amber = Redundant power supply failure Red = Power supply failure. No operational power supplies. Off = Normal (system off)
14	Overtemperature LED	Red = Overheating, critical Off = Normal
15	System power LED	Green = System has AC power and is powered on Amber = System has AC power and is in standby mode Off = System has no AC power

* If all FBDIMM LEDs for a memory board are flashing, the memory board is unseated.

 

nah untuk menangani nya , dari beberapa saran di forum HP ,

langkah pertama cabut  baterai dari system board , langkah ke dua cabut memori board kemudian masukan lagi, langkah ke tiga masukan lagi baterai ke system board(mother board)  terakhir  coba boot lagi ,

dari saran di atas jika masih belum bisa boot dan led Internal system health masi menyala merah , di langkah ke dua setelah cabut memori board , cabut juga satu persatu memori nya kemudian pasang lagi dan coba boot ulang.

semoga bermanfaat  :)

Menambahkan ICONS host yang di monitor di Nagios

Bismillah ,
folder icon di nagios ada di

 /usr/local/nagios/share/images/icons/

kemudian upload icon ke folder tsb , bisa menggunakan tool scp seperti winscp atau filezilla , contoh icon bisa di download di link berikut

https://drive.google.com/file/d/0BwWfj12MiwgkbEM0eXdIQUVVNHc/view?usp=sharing

untuk memberikan icon host yang kita monitor di nagios , kita bisa tambahkan di file configurasi nagios contoh nya

root@serveraldy:~# pico /usr/local/nagios/etc/servers/clients.cfg

#                                                          #
#                   CLOUD 2                                #
###############################################################
define host{
use                             linux-server
host_name                       cloud2
alias                           CLOUD 2
address                         192.168.222.10
contacts                        nagiosadmin
contact_groups                  admins
max_check_attempts              5
check_period                    24x7
notification_interval           15
first_notification_delay        0
notification_period             24x7
notification_options            d,u,r,f,s
notifications_enabled           1
check_interval                  5
icon_image                      proxmox_logo.jpg
icon_image_alt                  proxmox_logo.jpg
vrml_image                      proxmox_logo.jpg
statusmap_image                 proxmox_logo.jpg
}

kemudian restart

root@serveraldy:~# service nagios restart
Running configuration check...
Stopping nagios:. done.
Starting nagios: done.
root@serveraldy:~#

hasil nya kurang lebih seperti ini



oh ya , silahkan sesuaikan ukuran gambar nya , jika tidak di sesuaikan maka akan kacau hasil nya :) kaya di bawah ini hehe



selamat mencoba , semoga bermanfaat :)
