Hi,

We are trying to install a MD3200 and are having a few issues with setting up the failover ability (between 2 cards and 4 ports). I've installed a few MD3000s and always used the multipath driver. After reboot everything would show up correctly and I could partition the virtual disk without any issues.

From what I can tell the MD3200 now uses rdac to handle the failover ability. I followed the steps and partitioned the /dev/mapper device but we are still getting corrupted blocks. Fdisk -l is still showing multiple devices /dev/sdd and /dev/sdf with 4TB when there is only 4TB total.

We are running CentOS 5.5 and renamed the redhat-release before installing. Can we not use the multipath driver? Do we still have an issue with rdac because it is showing twice in fdisk? I also see the 20MB sizes which I believe are the raid controller cards? This usally went away after installing the Dell Storage manager on the MD3000s. I've called Dell on this and haven't made much headway with it so I thought I would post up here.

Thanks,
