Yeah - five (I think) hot swap drive bays in the front of the box, all on an SAS backplane. mark -- Nuclear physicists speak of five fundamental forces: weak, strong, electromagnetic, gravity, and duct tape. -- American Science and Surplus Catalog ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] Dell R605 w/ Perc 6/i problem
this sounds like the right solution, you can do this either form the firmware or the megaraid command line tool MegaCli64 (MegaCli for non-64 bit systems) On 2010-06-30, at 7:18 AM, Eero Volotinen wrote: 2010/6/30 mark m.r...@5-cent.us: Jacob Bresciani wrote: R605 is a power edge server model I think.The Perc6/i is a Dell rebranded raid controller, it's actually an LSI in disguise.

Re: [CentOS] Dell R605 w/ Perc 6/i problem
Thanks, everyone. Making the single drive a RAID-0 was the answer. From the boot, it was ctrl-R, and then follow what y'all were saying. As soon as I did that, and had the controller software make it bootable, when I got out and went into the CenOS install, everything was wonderful - I even saw what had been on there (before I blew it all away). Thanks again. mark ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

R605 is a power edge server model I think.The Perc6/i is a Dell rebranded raid controller, it's actually an LSI in disguise.
