Hi! Im new to the forum, also with Supermicro servers. I ordered a 36 bay server wich has two backplanes. One 24 disk backplane (model nr: bpn-sas2-846el1) and a 12 disk backplane.
here is the problem:
- In the raid config (raid card is LSI MegaRaid 9271-8i), only the 12-disk backplane and attached disks shows up.
- Ive tried switching SFF cables and outputs on the raid card.
- The disks blink for half a second after I press the power button/startup. On the backside (pointing inwards into the server) of the backplane I can see a solid blue light.
- Ive tried with a different PSU to power the backplane.
- The seller said it was working before it was shipped.
- Ive now tried with a HBA IT mode card, and only the disks attached to the 12-disk backplane shows up in ubuntu.
What Im I missing?
