Has anyone successfully installed MSL on to Dell R540 with PERC H750 Raid controller? We ordered new servers from Dell that shipped with new RAID controllers that are not on the Mitel compatibility list. Tired using RAID5, RAID1, RAID0. During the MSL install the server boots to the DVD and then right after selecting keyborad type, it Comes back and says " No Useable Disks found". I just installed MSL on to another DELL R540 with PERC H730 Raid controller and that went through no problem. Called Mitel Support and found that new RAID controller is not yet documented or tested. Called Dell and they told me MSL is not an OS that they test against. Dell suggested I configure server as EXSI and run as VMware. Just curios if anyone else has run into this yet.
