Before you do this...  Are these 5 drives the ONLY disks in that DAE?  On CX4 and older (ie: everything except VNX) you cannot mix SATA and FC disks in the same DAE.  Remove ALL FC disks from the DAE before inserting ANY SATA disks.  Before removing the disks, unbind any LUNs that are in RAID Groups that use those disks, then destroy the RAID Groups.  Do not make the disks into Hot spares or anything else.  They must appear as unused disks ready to be used for new RAID Groups.  After that you can remove the disks from the DAE.  Again be sure to remove ALL FC disks from the DAE before inserting ANY SATA disks, otherwise you could run into a data-unavailable event.  The old guidance was that you should zero out the disks before removing them, I've heard this is not really a requirement but if you plan to put those FC disks into another array, you might want to do it.  There is a navicli command you can use to start the zeroing process on each disk.  It will take several hours to complete.  Hope that helps.  Richard J Anderson
We have a need to replace some SAS drives with SATA. My plan is to take an existing 4+1 RD5 raid group of SAS and firstly destroy that raid group (data no longer needed). Subsequently i will set those 5 drives as hot spares. Can I then just pull those drives out of the DAE live and replace them with the required SATA ones ? or is this a system down function ?  thanks.
Hot replacing good drives from DAEs
