RE: [CentOS] CentOS on Dell Poweredge 2850
Ian Forde scribbled on Tuesday, September 16, 2008 8:35 PM: Our department's planning to buy a refurbished Dell Poweredge 2850 running dual-xeons and with a rather big raid array (8x 146GB). *My* plan is to install CentOS on this machine and I'd like to hear with you guys if there are any gotchas' doing this. My main concern is the ability of CentOS to recognise the raid-controller of the Dell and run a raid5-array as well as drivers for the onboard NICs. Any feedback on this is appreciated. I don't forsee any problems. I'm running CentOS 5.2 on a 2950 III and omreport installs fine without any problems. I can see the RAID array and monitor via the Nagios omreport plugins (search nagios-exchange for them). Onboard NICs shouldn't be a problem either... Thx. A former unix-admin at the dept thinks it might be a little on the old side hardware-wise, this particular server is about four years old. I'm split... This particular Poweredge modell is certified for RHEL 2 and 3. If I'd try to install RHEL5 on it, would bad things happen, or is it just a support issue? Seeing how CentOS 5.2 is equivalent to RHEL5, I don't see *what* could happen though...

I've had CentOS 4 and 5 running on several 2850's for a few years now - now problems at all. I've had disk failures - no problem just remove the disk and put in a new one - hardware automatically rebuilds. I've installed the OpenManage software without any problems either - before install you *may* need to change the string in /etc/redhat-release to make it look like RedHat official as I believe the software used to check that file - just change it back after install. (not sure if this is true of the later releases of OpenManage).

I am running Dell 2950 III and no issue with hardware recognization of CentOs (5.2 Final) The one small thing is I can not extend the RAID volume because at the beginning time we only have 03 HDD now when we buy new HDD we recognize that RAID controller (PERC 6/i) doesn't support add new HDD to existing volume :( so only a choice is rebuild it. Uhh... check the DRAC - you may be able to extend the RAID5 array from there underneath the OS. You also may be able to do it using omconfig after installing omsa.

I remember I found an article on Dell support site explain that PERC 6/i doesn't support that. At the beginning I only have 3 hdd, now I get more 3 hdd and after that I figured can not add new hdd to existing volume. I am not install Open Manage yet ...will try it soon PS: sorry all for OT Uhh... check the DRAC - you may be able to extend the RAID5 array from btw, how do you access to DRAC ? i configured IP address for it at firmware boot but can not see the interface for it. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
