I've been running a nas based on a HP DL380p Gen8 with a Netapp DS4243 shelf and an LSI SAS9200-16E HBA card. This setup has been running fine for a few years. I finally decided to replace the LSI card with an HP H221 so I can get proper fan control back, but it refuses to POST with the Netapp shelf connected, just sits at "Initializing..." forever. When I disconnect the shelf, it boots fine. Nothing shows up in the iLO log either. I already tried updating the card's firmware to the latest version, but it didn't make a difference. Does anyone have any experience with this?
