Just to share some experience with the DS3622xs+ loader and how to get a SAS HBA controller to work:
I use a Xeon based server (32GB Ram) with SAS Controller in HBA mode, connecting 4x 3GB SAS Hds. The 4 HDs were configured in DSM6.2 as 1 Volume in RAID10. The Forum here says that in DSM7 HBA adapters are not yet supported but I got it to work as follows:
- when configuring the Redpill loader I had to run the satamap command and despite the reported errors, the loader found my HDs after a few trials. Te loader does not detect any HDs if I omit running the satamap command so this is the essential step although it creates an error message stating that "there will be problems".
- after booting, DSM7 immediately detected my old Volume-1 but reported 2 out of 4 disks inside the RAID10 as defect
- nevertheless, all data on Volume 1 was available and accessible, even while the 2 HDs were reported as defect.
- I integrated the 2 ("defect") HDs via the DSM Storage Manager normal procedure to rebuild a RAID Volume
- This took 5-6h to rebuild and showed no errors. All 4 HDs are live as RAID10 again
- Since then the RAID10 runs under DSM7 without any issues
