How to shutdown a whole Clustered Data ONTAP? I believe I have got the answer

Entrance of Pear Coffee Shop (梨子咖啡館，中科店),
in Xitun District, Taichung City, Taiwan.

A DCADM student several months ago raised a very interesting question: "How to shutdown the whole Clustered Data ONTAP?"

I believe now I have got the answer. It is by executing this command and then power off all nodes.

system node halt -node * -skip-lif-migration true -inhibit-takeover true

I verified the shutdown was clean on a two-node cluster running Data ONTAP version 8.2. I believe it would also work for more nodes.

NVRAM Battery Warning on NetApp Data ONTAP

It looks to me we have to power up our lab gears for longer time. Otherwise, this warning message will come back again and again! :)

WARNING:  The battery is unfit to retain data during a power
          outage.  This is likely because the battery is
          discharged but could be due to other temporary
          conditions.
          When the battery is ready, the boot process will
          complete and services will be engaged.
          To override this delay, press 'c' followed by 'Enter'

CAUTION: Using this appliance without NVRAM
         battery backup coupled with a power
         failure condition CAN CAUSE DATA LOSS.
Are you sure you want to continue (y or n)? y

ISDP, Industry Standard Discovery Protocol

I just learned the existence of this interesting protocol.

Industry Standard Discovery Protocol 

The Industry Standard Discovery Protocol (ISDP) is a proprietary Layer 2 network protocol that inter- operates with Cisco→ devices running the Cisco Discovery Protocol (CDP). ISDP is used to share information between neighboring devices. The switch software participates in the CDP protocol and is able to both discover and be discovered by other CDP-supporting devices.

台北市萬華區康定路46巷口的陸橋

Google Maps 街景

這座陸橋，就在台北市 西門國小 旁邊的 康定路 上。

我的童年，幾乎每一段回憶，都跟這一座陸橋有關。從國慶煙火、閱兵的阿兵哥、捉迷藏、一步兩階一步三階爬樓梯、等爸爸、看汽車、學腳踏車、牽腳踏車、滑板車、丟垃圾、水鴛鴦、紙飛機、國小排路隊回家，還有插滿的國旗和標語。

我剛才經過的時候，他已經不在了。從家人那裡知道，原來是星期日 (2014.1.5) 凌晨，他被拆掉了。

R. I. P. ，那些年，我的童年。
