These patches by Dan Williams enable creating RAID array based on SCSI enclosures. mdadm gets information about SCSI enclosure through ses module in kernel, and creates array for HDDs in an enclosure. New udev rules are added to make drive swap in the enclosure based array easier. Typical array create flow looks like: /* examine enclosures in the system */ mdadm --detail-platform --brief --enclosure > /etc/mdadm.conf /* create policy for enclosure0 and enclosure1 */ echo "POLICY domain=domain0 action=spare slot=enclosure0" >> /etc/mdadm.conf echo "POLICY domain=domain1 action=spare slot=enclosure1" >> /etc/mdadm.conf /* add md-ses program */ echo "PROGRAM /usr/share/mdadm/md-ses" >> /etc/mdadm.conf /* create md0 and md1 */ mdadm --create /dev/md0 enclosure0 -n 15 -l 6 -e 1.2 -c 1024 --run mdadm --create /dev/md1 enclosure1 -n 15 -l 6 -e 1.2 -c 1024 --run /* add array to mdadm.conf */ mdadm -Eb enclosure0 enclosure1 >> /etc/mdadm.conf /* create udev rules that add drives to array */ mdadm --udev-rules --enclosure > /lib/udev/rules.d/65-md-raid-hotswap.rules Dan Williams (15): udev rules and infrastructure for /dev/disk/by-slot mdadm: allow a /dev/disk/by-slot as domain path descriptor 'act_spare' should be the minimum requirement for dynamic domains fix variable offset when ':' is present in the device name imsm: quiet detail platform ses: workaround sysfs deprecated prepare for enclosure platform details enclosure detection/enumeration Add --brief support to --enclosure config: ENCLOSURE keyword and enclosure device list expansion policy: enable enclosure names for domain definitions invoke hot-add policy on "change" events Toggle enclosure leds in response to raid events scsi mode sense/select support SCSIMODE: configuration file support for mode page settings.
