I am trying to help a friend with a 2850 and snmp monitoring of a controller and its arrays. I don't have any dells, do they have a rpm to make easy work of this for the Percs? They have a monitoring solution already. Any hints I could pass on would be appreciated!
Thanks, jlc

I haven't tried to setup Dell's SNMP stuff, but I did download their driver development kit and wrote a perl script to wrap around their "raidcfg" utility to detect a bad(missing) disk.
[root@pd1-bgas01 ~]# /usr/lib/nagios/plugins/check_dell_raid OK: Both drives OK in disk subsystem Controller: PERC 4e/Si VDisk ID: 0 Size: 286080 MB (279 GB) Type: RAID 1 Read Policy: Adaptive Read Ahead Write Policy: Write Back Cache Policy: Direct I/O Stripe Size: 64 Drives: 0:0:0,0:1:0
The script assumes that there are only 2 disks, and if it doesn't see two disks in the Drives: line will spit out a warning.
It does require root access so my nagios calls sudo in order to call the script.
The script is here http://portal.aphroland.org/~aphro/check_dell_raid.txt
I'm not a programmer so my scripts aren't the neatest by anyone's standards I'm sure but it does work for me I have it deployed to about 75 systems at the moment and it runs every 5 minutes. I did find that the raidcfg tool that dell provides does seem to crash some systems(2850s if I recall), but that could be because the kernel was too old or something. The script checks the model of the server and will refuse to run unless it matches.
I believe the source dell files are here: http://support.dell.com/support/downloads/format.aspx?c=us&l=en&s=ge...
I install these RPMs on my system for comparison: ./i386/srvadmin-hapi-5.3.0-266.i386.rpm ./i386/srvadmin-hapi-dtk-5.3.0-266.i386.rpm ./i386/srvadmin-ipmi-5.3.0-266.rhel4.i386.rpm ./i386/srvadmin-omilcore-5.3.0-266.i386.rpm ./i686/dell-dtk-2.5-1.i686.rpm ./noarch/dkms-2.0.13-1.noarch.rpm ./noarch/openipmi-33.13.RHEL4-1dkms.noarch.rpm
(the dell-dtk rpm is a custom one I built with the dell tools, the rest are direct from dell).
I've only tested these on CentOS 4.x and RHEL 4.x. Have not tested on 5.x.
Certainly wasn't as easy as using HP's hpacucli utility that is available to scan HP's storage arrays.

Now that I've looked at it more, it's the Dell Deployment Toolkit not the Driver development kit(if there is one, not sure).

I am sure you and Al's post will be sufficient!

OT: I would sure love to get this working inside of busybox so I could use it on my esx 3.5i server w/ an MSA20 on it :) Any tips?
Thanks everyone! jlc
