-**Rules**
+===== Rules =====
+  * Never pull a SATA drive out of a running array
+    *Shut the server down first
+    *Hot-Swap SATA is a myth
+  * Always back up a degraded array before screwing with it
+    * Be afraid!
+  * Never buy Adaptec RAID controllers
+    * Especially SATA/SAS
+  * Never trust the output of ''arcconf''
+    * Carefully reboot the server and verify using the BIOS
+===== Adaptec CLI Tools =====
+These commands download and extract the ''arcconf'' tool:
+<file>
+wget ftp://ftp.supermicro.com/CDR-LPZCR1_1.11_for_AOC-LPZCR1_AOC-SOZCR1/ASM/ASM4859/linux/StorMan-4.11.i386.rpm
+rpm2cpio StorMan-4.11.i386.rpm | cpio -ivmur '*arcconf'
+</file>
+Name it ''/usr/sbin/arcconf''.
+<file>
+chmod +x /usr/sbin/arcconf
+arcconf getstatus 1
+arcconf getconfig 1
+</file>
+===== Monitoring Script =====
+<file>
+#!/bin/bash
+# raidmon.sh
+#
+# The intent of this script is to be run frequently from cron to alert a
+# sysadmin to RAID problems with Adaptec controllers
+# Who to send alerts to
+ALERT="you@yourdomain.com"
-  * Never pull a SATA drive out of a running array - shut the server down first. Hot-Swap SATA is a myth.
+# Where is the arcconf utility
-  * Always back up a degraded array before screwing with it.  Be afraid.
+ARCCONF="/usr/sbin/arcconf"
-  * Never buy Adaptec RAID controllers - especially SATA/SAS
-  * Never trust the output of arcconf - carefully reboot the server and verify using the BIOS.
