alright folks , first of all thanks for the help if i get a answer.
we are always on the look to test out some new stuff and this time we want to test Storage Spaces Direct,
in case it proves to be good , we can implement this in production.
for testing purpose i use 2 HP DL380 Gen 9 servers , i had some problems getting the disks to be recognized as SAS in Windows Server , but after a bit of google time i found out that after deleting all of the RAID config's on the HP P440ar and putting it into HBA Mode , it is possible.
then , after upgrading the server with the latest SPP i am now able to see the drives come up as SAS, so finally i thought i was able to start using S2D , but no , thats not the case.
at this point the 2 servers are identical , and they both have 2 SAS HDD 10K 146GB drives and 4 SAS SSD 460GB drives in there.
i installed windows server 2016 in UEFI mode on one of the 460GB drives , you could ask me why but i had some issue's installing and i just wanted a working system to test out S2D , i didn't cared about the storage at that point because after the Lab i'm erasing the configuration.
at this point , all i am trying to do is execute the command Enable-ClusterStorageSpacesDirect but i get a error straight away , saying S2D is not supported on my system , i verified the drives are shown as SAS in server manager , but when i run the cluster validation test , and specifically the storage spaces direct tests , i get the following error on one of the drives :
Disk is a boot volume. Disk is a system volume. Disk is used for paging files. Disk partition style is GPT. Disk has a System Partition. Cannot cluster a disk with a System Partition. Disk has a Microsoft Reserved Partition. Disk has a Basic Data Partition. Cannot cluster a disk with a Basic Data Partition. Disk has a Microsoft Recovery Partition. Disk type is DYNAMIC.
this error makes sense , since i had to install my OS on once of the drives , but what does that mean at point of configuration , did i made a mistake or can i exclude one of the disks ... i could use some help understanding this a bit better.
