> Can you post results of lspci -vv for these controllers, please? I'd love to except that they're both running windows right now, and are Domain Controllers so can't be brought down to check. The closest info I can give you from Windows is the following: PCI\VEN_9005&DEV_0250&SUBSYS_02791014&REV_02 PCI\VEN_9005&DEV_0250&SUBSYS_02791014 PCI\VEN_9005&DEV_0250&CC_010400 PCI\VEN_9005&DEV_0250&CC_0104 I do know for sure they are rebranded Adaptec units as both the 7k & 6M controllers have Adaptec branded batteries attached to them and in the case of the 6M have the Adaptec logo silkscreened on the card. Both the 6M & 7k controllers, show the same vendor & device id's. From tracing this back to the pci id database these are IBM rebranded adaptec controllers. Linux uses the ips driver to handle these. I was testing the machine w/ 6M back in July with CentOS but I didn't see anything in the RAID bios that indicated it could. I also wasn't really using the HW RAID (except for the boot drive) during testing as I prefer to use mdadm where possible over HW RAID. -- Drew "Nothing in life is to be feared.
