HYPER-V : Device eth0 does not seem to be present, delaying initialization

Pagi-pagi gue mendapat telepon dari team Customer Service ISP yang dipakai oleh kantor, menginformasikan kalau mailserver milik kantor terdeteksi mati. Bergegas gue lakukan pengecekan, setelah terhubung dengan server host Hyper-V, gue coba cari status dari mailserver gue

# ifconfig

dan ditemukan kondisi bahwa tidak ada interface ethernet yang dipakai saat ini.

 lo Link encap:Local Loopback
 inet addr:127.0.0.1 Mask:255.0.0.0
 inet6 addr: ::1/128 Scope:Host
 UP LOOPBACK RUNNING MTU:65536 Metric:1
 RX packets:0 errors:0 dropped:0 overruns:0 frame:0
 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
 collisions:0 txqueuelen:0
 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)


Kemudian gue coba lakukan restart service

# service network restart

hasilnya malah mendapatkan pesan ini

Bringing up interface eth0: Device eth0 does not seem to be present, delaying initialization

Asumsi gue, interface ethernet ini mati. Gue langsung coba untuk menyalakan kembali dengan menggunakan perintah

# ifup eth0

masih mendapat pesan yang sama

Device eth0 does not seem to be present, delaying initialization

Ternyata masalah ini terjadi karena MAC Address yang di pergunakan failed.  solusinya cukup mudah yaitu mengganti MAC Address untuk Server ini dari sebelumya dynamic menjadi static.

IBM Thinkpad Secure Drive Red Blinking

I have a task from my user about his Thinkpad secure drive. The Secure Drive is look like the picture below.

His Secure Drive always show blinking red repeatedly, and he cannot input the password to unlocke well. From first impression, this conditions means the secure drive come into locked mode. and i think it's cause by he always put the worng password over and over again.

To get into unlocked mode, i do the following action :

1. Disconnect the secure hard drive from your computer.
2. Hold 5 while reconnecting the secure hard drive to your computer. The status LED alternately flashes in red and in green.

3. Press 5278879 and Press OK. The status LED turns red, indicating that the secure hard drive is unlocked for additional password attempts.

For further informastion, it can read at this documents.
