If you scroll up, do you see any departure notifications? They should look like this: mps0: mpssas_prepare_remove: Sending reset for target ID 10 da0 at mps0 bus 0 scbus0 target 10 lun 0 da0: <ATA Hitachi HUA72201 A39C> s/n JPW930HQ15H26H detached mps0: Unfreezing devq for target ID 10 xpt_release_devq(): requested 1 > present 0 (da0:mps0:0:10:0): Periph destroyed Also, could you post your HBA and expander firmware versions? For the HBA, use "sysctl dev.mps.0.firmware_version". For the expander, install sg3_utils and do "sg_inq --hex --len=64 ses0". The firmware version is the dotted quad at the end. # sg_inq --hex --len=64 ses0 00 0d 00 05 02 34 00 40 02 41 49 43 20 43 4f 52 50 ....4.@.AIC CORP 10 53 41 53 20 36 47 20 45 78 70 61 6e 64 65 72 20 SAS 6G Expander 20 30 62 30 31 78 33 36 2d 31 2e 31 31 2e 31 2e 31 0b01x36-1.11.1.1 30 00 20 20 20 20 20 20 20 -Alan
