Hello Eric,   A "Not approved" message indicates that drive is NOT an EQL approved drive.  You can remove it without impacting the RAIDset.    It sounds like you are running RAID50?   Since there should be two spares in that case.  Sounds like the RAID status is healthy so there's no need to bring the other spare into the RAIDset.     Regards,  Don   
I have an EqualLogic PS6100, which is out of warranty and we are unable to source replacement drives for.  We have recently purchased a new EMC SCV3000, which will replaced the older unit.  We are in the process of moving all VM's and data out of the PS6100, but this will take many months to accomplish.  Our issue is that we have one drive, in slot #5, who's Disk Status is "Yellow" and reporting "Not Approved" and it's Health is reporting "Not Available."  This disk is an original disk of the system, to my knowledge.  In slot #22 we have a disk who's Disk Status is "Blue" and reporting "Spare" and it's Health is reporting "Healthy."  It is my understanding that when the PS6100 sees a failed disk and has a spare on hand, it will automatically make the spare a RAID member.  This does not appear to be the situation in our case.  My first thought was to swap the drives, however I have also read of warnings about removing disks from the PS6100 and that it could lead to data failure. Does anyone have any experience with a failed drive who might be able to advise me on the correct path to take?   Thanks in advance - Eric
