I'm trying to attach 6 drives to one node, but only 5 are detected by the RAID controller (LSI MegaRAID SAS 9260-8i)
I purchased all the cables necessary: one with 4 SATA connectors, and one with two.
Full setup is 6 SATA drives to node 1 and 6 SAS drives to node two. Both RAID controllers see only 5 drives, and it's always the 4th fdrive that is missing.
Tried on three nodes, and always the same Looks like a repetitive error.
Also, when I connect the drives directly to the RAID controller (bypassing the backplane) all drives are visible.
