Hi, I am using two Promise TX4 SATA II 150 controllers in one computer. To the controllers three hard-disks for backups and three hard-disks for a RAID3 storage (graid3) are attached. The idea was to change the hard-disks for the backup via hotswap on a regular basis, while the RAID disks remain untouched. But if I (remove and) connect only one backup disk while the system is running then FreeBSD also re-connects many (but not all) uninvolved SATA drives. At the end, the RAID is broken which is not so good... Is there a way to block the hotplug feature for the RAID - ATA channels ? Or is there another workaround/fix?
