Not all drives seen

I am new to TrueNAS and am using a retired server to experiment and learn.

I have an old HP DL380 G7. I installed a LSI 9211 card and moved the mini-SAS cables from the on board controller to the new card.

After installing TrueNAS, it doesn’t see all of the drives installed. I’ve read some posts about issues with breakout cables. Do I need different cables from the drives backplane to the card?
