Unmap the volume from the SDC linux host using the 'scli --unmap_volume_from_sdc' command and remove the SDC from the SIO config  using 'scli --remove_sdc' - see the EMC ScaleIO CLI Reference Guide for info on both of these commands. You can find the guide at [URL] Remove the logical device from the OS - see your linux guide. Remove the SDC driver from the OS.
Supposing that I have successfully mapped a volume to SDC Linux host and SDC device /dev/scinia can be listed in Linux host as below: # ls -l /dev/disk/by-id/ |grep scini lrwxrwxrwx. 1 root root 12 Jan 25 16:37 emc-vol-189d8c9c1f41f458-a7b0341500000001 -> ../../scinia If this SDC device is no longer in use by SDC Linux host anymore, how do I properly remove this SDC device /dev/scinia in host level before I unmap it in ScaleIO?  Thanks for help.
