> I was one of the people with trouble before christmas. Following mike's stirling work they seem to function well in recent stable snapshots. At the time I last installed the GENRIC kernel and sysinstall didn't have the aac configured so I had to use a set of current install floppies having changed options/Release Name to correspond to the stable snapshot I required. There are couple of things to know about Dell PERC controllers. PERC stands for Power Edge Raid Controller. Hence can be anything Dell decice to rebadge. Currently this seems to be restricted to the aac (adaptec) and amr (AMI). The PE2450 has an onboard aac that is enabled with a "raid key' and and a DIMM. This is the PERC3/si. THis seems to be a reasonable controller, the drivers reporting seems to suggest actual PCI controllers of this family may have a battery to protect the uncommited data data in the (large) cache, while this does not. (Write cacheing can be disabled.) While there is no native freebsd managment tool for this card, work is well under way on getting the linux one working and most tasks can be initiated in the contollers bios at boot time and left to happen in the background while FreeBSD runs on the 'degraded' . This means a reboot would be required for most recovories, thogh much of it may be able to occur with the machine up and running. I am not sure of the state of managment tools for the other RAIDS, if you have the time and budget to pick and choose this is an importent criterea. -- GeoffB To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
