Hot-spare warning on Dell servers

When assigning a global hot spare in a system with multiple arrays, the warning "The global hot-spare drive Disk 0 in Backplane 1 of Integrated RAID Controller 1 does not cover all the virtual drives (VDs) available on the controller" or "Insufficient space on the global hot spare Disk 0 in Backplane 1 of Integrated RAID Controller 1" might appear if one of the arrays either uses drives larger than the hot spare, or if the hot spare is an HDD and one of the arrays is SSD.
