[SOLVED] Help figuring out why my setup won't see 4Kn drives

[DieFalse]

Hello everyone,

 

I have a problem I don't understand enough to know what angle to go about fixing it.

 

I have acquired some 4Kn drives (8tb SAS drives) that my rig was supposed to be able to handle,  The backplane's are SAS compatible and I have the following HBA Setup:

 

2x  LSI SAS3008 - 9300-8i cards

2x RES3TV360 expanders powering my 42 bay rig.

SFF-8643 to SFF-8643 from the HBA to the expander.

SFF-8643 to SFF-8087 from the expander to the backplane.

 

Googling shows that the 9300-8i's should detect and work with 4Kn and I can't find any reason the expanders won't.

 

Any idea's?  I would really like to add the 10 8tb drives to my rig.

Google "3.3v sata pin" if it's not that then please post the diagnostics: Tools -> Diagnostics

I have a couple normal drives that have the 3.3v pin,  the 4kn sas drives do not have this pin that I can tell.

Nevermind.   Turns out they do have 3.3v pins.   Removed and they are working as expected.  Thanks!

Thanks for reporting back, if you don't mind I'm going to tag it solved.

absolutely.  if you don't mind, can you see if you see anything in the diags that needs addressing?  im good otherwise.

Only took a quick look but everything looks normal, though there are a lot of nerdpack tools installed, make sure you need them all.
