This will be a cleaner and easier method. Re-install the ESX preserving the VMFS, the new installation will detect the megaraid as it now operates in raid mode. to include the Megaraid2 controller driver - This is a tricky one and need to be very careful not to break the server which is currently booting.Ģ. Re-built the boot image ( depends on ESX version). Also lspci -v output from console the esxi.ġ. Now to go further i need following details: The version of ESX you are using, and server model you have. Can you please make sure this server you are using is supported by VMware for the specific version. And VMFS is hosted on a different storage ?Īs you can see your controllers are still using libata controllers which makes the system to work as normal scsi cards. If i am not wrong i hope you are using two SATA drives to create a RAID1. In your driver list there is no megaraid driver loaded. I am not certain of the RAID controller model -it's an LSI controller, but I'd have to reboot to see any info about it and I've done too much of that lately - don't want to reboot again until I absolutely have to.Įxactly, This is the card which i have seen in old dell servers which works in both modes ( SCSI and RAID). VSphere Security documentation for more information. ![]() The ESXi Shell can be disabled by an administrative user. VMware offers supported, powerful system administration tools. ![]() Output of esxcli system module list command: I'd prefer ESXi see the mirror as the single logical volume the RAID card is supposedly offering, but I will settle for ESXi ignoring the second drive altogether. The second drive is not part of a datastore. I am relatively certain that the RAID card is maintaining the mirror. ![]() vSphere shows both drives as physical drives mounted in the system. When I bypass this error with the command-line boot option " overrideDuplicateImageDetection", ESXi boots from one of the two drives. However, ESXi, on boot, sees both physical hard disks (seemingly ignoring the controller's supposed configuration, which is strange to me), and since they both contain identical copies of the ESXi install, it purple-screens complaining about two identical UUIDs. The controller did so and displays a single virtual volume (in its BIOS) as a RAID 1 volume comprised of the two physical disks.Īt this point I would expect any server OS to see the single volume. I am allergic to non-redundant drives, so I added a second drive and, from the RAID controller's boot BIOS (pre-boot of the server itself) I created the mirror and had the controller "rebuild" the second drive, copying an image of the first drive over it. This server has an LSI RAID controller and had a single hard drive attached to this controller. It has a number of VMs and has been working. Please bear with me as I try to explain this problem fully.
