RAID commands

My controller is a 3Ware 9260-8i with firmware 3.27.00 The controller is 1000:0079, MegaRaidSAS http://hwraid.le-vert.net/wiki/LSIMegaRAIDSAS

The drive is a WDC WD30EFRX "Red".

I have not gotten the RAID command line program running yet on this OS (Debian 8).

At boot time, you can type Ctl-Y when prompted to bring up a command prompt. "$" There is no "help" option -- I found some scant documentation online, here are references

When a drive failed, I had to turn off the ALARM! It's LOUD, you can't miss it. It beeps once per second to tell you a drive is gone.

I have only one controller so I can use -aALL or -a0

Silencing the alarm

AdpSetProp AlarmSilence -a0
AdpSetProp AlarmDsbl -a0

Replacing the drive

There is a walk through on this page: https://supportforums.cisco.com/document/62901/megacli-common-commands-and-procedures

[E:S]  =  Enclosure:Slot

Get information

adpallinfo -a0
encinfo -a0
ldinfo -lall -a0

Mark drive as missing

PDOffline -PhysDrv [E:S] -a0 
PDMarkMissing -PhysDrv [E:S] -a0 
PDPrpRmv -PhysDrv [E:S] -a0

Replace the drive

Rebuild

Software

• Debian 7
• mediawiki
• postfix not exim4

Postfix

Email is supported via Wildsong at the moment. That is, mail originates @wildsong.biz

• smarthost using gmail, because I use gmail for the Wildsong and Geo-CEG domains.
• sasl auth is needed to talk gmail

Mediawiki + MySQL

I decided to go w/ MySQL because of support issues (MySQL is sort of the "official" database of mediawiki), this means running both MySQL and PostgreSQL on Dart. Dart has lots of memory and the machine's not doing much anyway... The main reason I install PostgresSQL on Dart is for PostGIS.

Installing mysql means I install other stuff. Installing mediawiki calls for a few things too.

apt-get install mysql-server phpmyadmin postfix-mysql
apt-get install php-apc git

With MediaWiki, along come my favorite extensions.

PostgreSQL

I want version 9.3 or higher so I need to add a repo.

echo "deb http://apt.postgresql.org/pub/repos/apt/ wheezy-pgdg main" > /etc/apt/sources.list.d/pgdg.list
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | apt-key add -
apt-get update 
apt-get install postgresql-9.4

2015-Feb-27

I packed up Dart last May (2014) shortly after re-installing the operating system and switching to Debian. Now I am trying to pick up the pieces. There is no Web server right now! Zow! How can that be?

I do remember I gave up on CentOS when I found out how impractical it was to try to run my own copy of ESRI ArcGIS Server after I lost (free) access to a developer license.
