The disk is now worthless, so a LUN that is mapped from storage to the host may be large.

Recently encountered a problem: 2 Windows hosts to use as RAC, storage mapped to Windows a disk has a 10T size. As we all know, the shared disk in Oracle RAC under Windows, the concept corresponding to Windows Disk Management is the logical partition (logical partition) in the extended partition (extension partition), and the logical partition (logic Al partition) is not built under the GPT partition format. Also, when you convert the 10T size disk to an MBR partition, the maximum disk capacity supported by the MBR partition is 2T, so that the remaining 8T is wasted. Therefore, the tradeoff is to have the storage engineer map to the Windows host 5 LUNs, 2T size per LUN.
