I''m not having any luck hotswapping a drive attached to my Intel SASUC8I (LSI-based) controller. The commands which work for the AMD AHCI ports don''t work for the LSI. Here''s what "cfgadm -a" reports with all drives installed and operational: Ap_Id Type Receptacle Occupant Condition c4 scsi-sas connected configured unknown c4::dsk/c4t0d0 disk connected configured unknown c4::dsk/c4t1d0 disk connected configured unknown c4::dsk/c4t2d0 disk connected configured unknown c4::dsk/c4t3d0 disk connected configured unknown c4::dsk/c4t4d0 disk connected configured unknown c4::dsk/c4t5d0 disk connected configured unknown c4::dsk/c4t6d0 disk connected configured unknown c4::dsk/c4t7d0 disk connected configured unknown sata0/0::dsk/c5t0d0 disk connected configured ok sata0/1::dsk/c5t1d0 disk connected configured ok sata0/2::dsk/c5t2d0 disk connected configured ok sata0/3::dsk/c5t3d0 disk connected configured ok sata0/4::dsk/c5t4d0 disk connected configured ok sata0/5::dsk/c5t5d0 disk connected configured ok [irrelevant USB entries snipped] Now, if I yank out a drive on one of the AHCI ports (let''s use port 3 as an example), I can use: cfgadm -c connect sata0/3 cfgadm -c configure sata0/3 and bring the new drive online. I have had no luck with the SASUC8I; even though I can see messages in the system log that a drive was inserted, the only way I''ve been able to actually use the drive afterwards has been via a reboot. A command like: cfgadm -c connect c4::dsk/c4t4d0 will be greeted with the message: cfgadm: Hardware specific failure: operation not supported for SCSI device Is "cfgadm -c connect c4" sufficient, or is there some other incantation I''m missing? :)
