+=== 3.3.3. Periodic checks ===
+
+You can write your own script around megacli to check your adapter status health periodically. 
+However, I already did this for you. See megaclisas-status below.
+
+== 3.4. megaclisas-status ==
+
+=== 3.4.1. About megaraid-status ===
+
+'''megaclisas-status''' is a wrapper script around '''megacli''' that report summarized RAID status with periodic checks feature.
+[[BR]]It is available in the packages repository too.
+
+The packages comes with a python wrapper around megacli and an initscript that '''periodic''' run this wrapper to '''check status'''.
+[[BR]]It keeps a file with latest status and thus is able to detect RAID '''status changes and/or brokeness'''.
+[[BR]]It will log a ligne to '''syslog''' when something failed and will send you a '''mail'''.
+[[BR]]Until arrays are healthy again a '''reminder''' will be sent each 2 hours.
+
+=== 3.4.2. Wrapper output example ===

+= 3.5. About /dev/megaraid_sas_ioctl_node ==
+
+All theses tools requires this device node to be created.
+[[BR]]It has to be done by hand.
+
+Proprietary tools creates the device node at startup.
+[[BR]]I made some wrappers around binaries from megactl package to create the node if it doesn't exist yet.
+
+[[BR]]
+= 4. BIOS upgrade from a Linux system =
+
+Dell cards can be flashed using firmware-tools.
+[[BR]]See http://linux.dell.com/wiki/index.php/Repository/firmware for more informations.
+[[BR]]However this will only work on !RedHat, CentOS, SuSE and Fedora. Even Ubuntu is listed in the wikipage, LSI card upgrade is not supported.
+[[BR]]We use a Fedora 8 nfsroot booted by PXE to update our Dell's firmware running Debian.
+
+We don't have any informations yet about upgrading non-Dell cards.
