Dell Server (9g) notes
Warning: Some of the notes below only apply to Dell's 9th server generation
Infos about 2013's 12th generation can be found at http://linux.dell.com/wiki/index.php/Repository, Ubuntu/Debian hints at http://linux.dell.com/repo/community/deb/latest/
Dell/Linux notes, general:
linux.dell.com is always a good start and Debian/Ubuntu users can be looking forward to see more support there.
While several former PERC- and MegaRAID drivers provided all important things somewhere under /proc/, and Dell there been several tools by Dell and others, like OpenManage*, mptlinux, mpt-status, srvadmin, ..., my gut feeling is that srvadmin (apropriate for RHEL) and finally dellomsa (apropriate for Debian from 2.6.18 on) are the right packages to just cron-check the health of e.g. RAID disks.
srvadmin and RAID status on RHEL5 systems:
From Dell's OMSA repository hints:
wget -q -O - http://linux.dell.com/repo/hardware/latest/bootstrap.cgi | bash
yum install srvadmin-all
srvadmin-services.sh start
omreport storage pdisk controller=0
dellomsa and RAID status on Debian systems:
Based on Dell's Debian-on-9g-Servers hints:
echo "deb http://ftp.sara.nl/pub/sara-omsa dell sara" >>/etc/apt/sources.list.d/sara_nl.list
apt-get update
apt-get install openipmi ipmitool dellomsa
omreport storage pdisk controller=0
In the first place, the deb line was using ftp:, but http: seems to work also and is more propable to be accepted through corporate firewalls.
omreport usage:
I have not yet found a manpage or the like, but when called like ...
omreport -?omreport storage -?
... (and so on) omreport a least lists the crucial commands and options.
Interesting reports I found include RAID system battery ...
omreport storage battery
... Power supplies (especially when a server has 2 of them) ...
omreport chassis pwrsupplies
... and always the temperatures:
omreport chassis temps
omreport based check-HW-RAID.sh cron script:
This can serve as template for a cron job checking your HW RAID:
#!/bin/sh
RAIDFAILS=$(omreport storage pdisk controller=0 |grep Status |grep -n Status |grep -v Ok)
# the grep -n is not redundand, it "prefixes" the disc number to each status line
test -z "$RAIDFAILS" && exit 0
echo "HW RAID is failing" |alert-the-admin
Service Tag detection on all Linuxes:
From Dell's PowerEdge hints:
Find the Dell Service Tag number easily:
hwinfo --bios | grep -E "System Info|Serial:" | grep -n1 System | tail -n1 | sed 's/"//g' | awk '{print $3;}'
The above line works on Debian and SuSE systems, RedHat has not yet consumed the hwinfo tool yet.
This seems to work on RedHat based systems:
dmidecode | grep -E "Serial Number" |head -n1 | awk '{print $3;}'
From: IBCL BLog.
