Raid 5 Monitoring on Dell Power Edge 2650 With Afacli
I had to monitor the Raid 5 status of two PE 2650 with a PERC3/Di and running under a GNU Debian. You can get the CLI tool afacli from dell website. Originally it was only available for windows or red-hat and it was necessary to tweak this stuff using Alien software for converting rpm to deb packages.
nicolas@grimm:~$ wget http://linux.dell.com/files/aacraid/afaapps-2.6-0.tar.gz
nicolas@grimm:~$ sudo tar -Pvzxf afaapps-2.6-0.tar.gz
# Normally you should have a device afa0 created. If not, check that devicename = "aac" in the file /dev/MAKEDEV.afa then do the following step :cd /dev
Now that we have a running AFACLI we can do a little script for checking hourly our raid status. Main thing to know with afacli - as lot of other CLI tool - is the HELP command. First you will have to open your device with the command open afa0 then you could check your container list, disk list etc. Due to network constraint I could only use an SSH connection, so for schedule this script I use a special user named xfertuser on each box for doing an SSH KEY AUTH. When my user is logon the remote box, I execute some command on AFACLI and use a simple diff on last afacli log file and the new afacli log file. Then in last step Icheck the messages log for AACRAID error messages.
Here is a sample script to use in a hourly crontab :
