BitBucketeer Posted January 8, 2021 Share Posted January 8, 2021 (edited) Hi all, Long time tinkerer and lurker. I'm stuck with this problem and don't know how to solve it. UnRaid 6.8.3 Wanting to build a 24 drive UnRaid Have a Rocket 750 40 port HBA On power ON If I go: Rocket 750 -> drives: works perfectly All drives spin up simultaneously as soon as power is turned on. If I go: Rocket 750 -> backplane -> drives: times out and drives are taken offline. Drives spin up sequentially only after the Rocket 750 driver is initialized. However, if I press RESET after all the drives have spun up, the next boot is fine - all drives are found. So far I've tried: 2 different backplanes (one SAS x6, one SATA x 24) Tried setting the Rocket 750 to non Staggered Spin Up using the CLI Before I bite the bullet and spring for a 24 port LSI HBA (no room for port multipliers) - any suggestions? (I understand that newer versions of UnRAID no longer support the Rocket 750 so it may be a lost cause). Edited January 8, 2021 by BitBucketeer Clarity Quote Link to comment
BitBucketeer Posted January 15, 2021 Author Share Posted January 15, 2021 Gave up on the Rocket 750 and bought a new "LSI Logic Controller Card 05-25699-00 9305-24i 24-Port SAS 12Gb/s pci-e 3.0" from a Chinese seller on eBay for $399 USD. Works perfectly out of the box: - motherboard recognises the card - comes up with "Avago SAS3 BIOS" and enumerates the drives I have installed so far - boots UnRAID quickly with no timeout messages - drives recognised immediately by UnRAID Need to get more SFF-8087 to SFF-8643 cables as the card uses SFF-8643 connectors, but so far so good.
