The driver/feature matrix shows that the current version of sata_mv driver doesn't support hotplugging (but it may be added in future). -- Markku Kolkka [EMAIL PROTECTED] -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list

Aha, I shall do so. Just as a quick heads up, with the 3ware cards, you have to have JBOD support on, and a hotswap compliant enclosure for this. If you are using any type of RAID (I use RAID 5 on the three I have) it shows as one, maybe two drives (sda/b) in Linux though I have between 4-12 drives in the system. I have hot swapped failed drives before, but if you are using a JBOD setup, I am not sure how that works as seen from Linux, though the card handles all of that internally. The biggest thing to watch for in the logs with 3ware is are kernel logs and 3dm2 logs for the card if you have the support software up. according to the 'Driver / feature matrix' http://linux-ata.org/driver-status.html#matrix driver=sata_mv feature=Device Hotplug feature state=no Well spotted, I saw this bit of the same page... http://linux-ata.org/driver-status.html#marvell ... and it says: Driver name: sata_mv Summary: Similar to ServerWorks "frodo": per-device queues, full SATA control including hotplug.

SATA hotswap / hotplug
Hi list, I'm trying to get SATA hot-swapping to work in Fedora 9 but I'm either having no luck or doing it wrong.
