How to properly remove SDC device /dev/sciniX in SDC Linux host?
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.

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 https://support.emc.com/products/33925_ScaleIO-Software/Documentation/. Remove the logical device from the OS - see your linux guide. Remove the SDC driver from the OS.

G'day lkc, I thought about this last night and concluded that there is a cleaner way to do it...

Hi Matthews,
Thanks for your reply.
My question is how to remove it from OS Linux, it seems that the removal method is quite different from removing /dev/sda for example that we always do in OS level.
Would you please suggest a command/method to remove /dev/scinia in Linux platform before I unmap it in ScaleIO?
Many thanks.
