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).

Took the plunge and bought one of these off eBay. Works fine with 6.8.3.
There is a post in Bug Reports / PreReleases which indicates that it does not work with 6.9.0-beta25.
Rocket 750 and Staggered Spin Up causing issues

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.
