Running CentOS 6.7, on an older HP DL580 G5. We've got a Dell 12-bay RAID box plugged into a PERC H800 (aka LSI Liberator) that we put in the HP, and that works fine. We've got a new RAID (a JetStor), and are trying to plug it in.
The layout is that the Dell RAID is dual-pathed DAS. Each PERC has two DAS ports. We've got the Dell RAID in the top port of each PERC. I *thought* I could just plug the new RAID, which also has two ports, into the bottom two ports on the PERC.
TRied rescanning the SCSI bus, /sys/class/scsi_host/host[0-5]/scan, with no apparent sight of the new RAID. Can I do this the way I've got it, or do I need to daisy-chain the new RAID through the old RAID?
