Hi, I tried to remove a hot-swap RAID1 SCSI disk from the chassis. So I issued the following command > raidsetfaulty /dev/md4 /dev/sdd6 > raidhotremove /dev/md4 /dev/sdd6 But got the following message, /dev/md4: cannot hot-remove disk: disk is not in array! So I presume the disk is offline or something, and issued the following command echo "scsi remove-single-device 1 0 3 0" > /proc/scsi/scsi When I checked the newly created /proc/scsi/scsi, the device is still listed in the file. I checked /proc/mdstat and saw the following md4: active raid1 scsi/host1/bus0/target2/lun0/part6[0] 521984 blocks [2/1][U_] How do I remove the device, so I can add a new device to reconstruct the array again? Please give me a few pointers?
