Can't recognize 2 new drives after installing a SAS Expander?

Featured Replies

Hi all - I'm trying to dig through the system logs on this but they're a little over my head.

 

I installed a SAS expander card (HP 24 Bay 3GB SAS Expander Card 487738-001 468405-002 w 2x 28" + 1x 33" Mini-SAS) and 2 8TB SAS drives (GST HE8 8TB SAS 12Gb/s Nearline HDD).

 

Everything I had before the SAS card (4 x 2TB drives, 3 x 4TB drives) is recognized and working, but it can't seem to detect the new ones. I tried a few reboots, but nothing shows up in the unassigned devices.

 

*Update:* It was the drive. It was toast.

Anyone willing to help with this? 😕

How about other existing drive under expander ?

All the existing drives are there, it just can't see the new ones.

Are the disks detected if connected directly to the HBA? If not check the 3.3v line, some WD/HGST drives won't power up if there's 3.3v on the SAS/SATA plug, google "wd 3.3v pin"

Yes, forget that, check the 3.3v first.

Ah, ok. Thanks for the response!

 

I updated the firmware but that didn't work. By connecting directly to the HBA, do you mean bypassing the SAS card and going right to the motherboard's connection?

 

And if it's a 3.3v, would the tape trick work?

Bypassing the expander, in your case connecting to LSI onboard ports.

I'm halfway there! I got one device to read fine, but the other one is kind of recognized but doesn't seem to be working right:

I bought a couple of molex to SATA power cables and I have both drives connected to the same sleeved power supply cable (if that matters)

Google

molex to sata fire

and make sure the models you have are ok.

Assuming the devices are the same model try swapping cables/backplane slot between both, if the error stays with the disk that's likely the problem.
