Hi List; I just got a new server (my first **real** server). It's a dell 2900 : quad core XEON (with a spare slot for a 2nd quad core chip) 8G memory (expandable to 64G) 8 hot swap SATA HD slots onboard PERC6i RAID controller etc I initially setup the system / RAID as follows: 1) booted off the dell setup CD 2) walked through the RAID setup and formatted the drives 3) the setup bombed when it asked for a RHEL install media (I suspect cause I gave it a CentOS 5 install DVD instead) 4) powered off 5) restarted the box with the CentOS DVD in the drive and installed CentOS 5 The RAID configuration was as I had set it up in the DELL setup cd so I'm happy. Now I want to be able to monitor the box, specifically with respect to the RAID drives so I'll know if one has gone bad and the RAID configuration has failed over to it. Anyone have any suggestions for tools to use ? Thanks in advance...

LSI has a command line tool you can use to monitor them. MegaCli is more than just a bit obtuse, but a little bit of scripting goes a long way. -- Joshua Baker-LePain QB3 Shared Cluster Sysadmin UCSF

Anyone have any suggestions for > tools to use ?We use 3Ware RAID cards, and they have a CLI util called tw_cli. We run "tw_cli info c0" every hour into a rotating file. Then from crontab we run a script that diffs the current output to the last hour's output. If there's a difference, it emails us. -- Spiro Harvey Knossos Networks Ltd 021-295-1923 www.knossos.net.nz
JohnStanley Writes: Please see "linux.dell.com" and search for "OMSA". With just one machine it may be a little over kill but provides a GUI for all administration of the server. Other wise you can direct all inquiries to "linux-poweredge at dell.com", just sgn up for the list. There are also depending on your raid card, "Mega-Cli or PERC" Non GUI tools to assist you.

You shouldn't need to do anything that fancy just to find out if something fails. -- Bowie
