Hi,
what is the correct way to re-add a VMFS Datastore with two Extents after a defective RAID Controller had to be changed.
Situation:
- ESXi 5.5
- local RAID controller with two RAID Arrays configured
- a VMFS Datastore was created with one RAID Array and then expanded with the second RAID Array
- RAID Controller died in the ESXi Host
- RAID Controller was replaced with a similar controller
- RAID Controller shows both arrays as healthy
- rescan Datastores in ESXi doesn't mount a datastore
- the add HDD/LUN Wizard shows both RAID Arrays as possible Target with option to mount the datastore by keeping the signature, changing the signature or format the volume
- the original big Datastore is not shown in this wizard
- as far as I could find out both shown volumes are recognized as mirror LUN since they are accessed on a different path because of the RAID controller change
Question:
how to re-add the original VMFS Datastore containing both RAID Arrays and not loosing Data on the VMFS volume
