During my shuffling, I temporarily added two of the SSD drives and used them as normal drives (not in a storage pool). Later, I deleted the data from those drives and wanted to create a new storage pool with those two drives. However, I found that when I ran the wizard to create the new storage pool, the drives were missing (not listed). They were also not listed in the primordial pool.
Using Server Manager, I tried:
- removing volumes
- resetting the drives
- reinitializing the drives
- taking the drives offline and online
- changing between GPT and MBR
After a quick bit of searching, I found that running Reset-PhysicalDisk should change the CanPool property to True. And it did. My surprise is that resetting the drive using Server Manager didn't reset that property to True.
Once I reset the disks with Reset-PhysicalDisk, I was able to create a new storage pool using those disks. And my test server has never been faster!
