rmdev won't remove disk device AIX

Hi all,

I'm attempting to remove some EMC hdisk devices which we recently had made available to one of our backup servers. This is an AIX 5.3 server. When I try doing an rmdev I get the following:

root@********:/dev# rmdev -d -l hdisk495
Method error (/usr/lib/methods/ucfgdevice):
0514-062 Cannot perform the requested function because the
specified device is busy.

I've attempted to disable the fcs device and THEN remove the hdisk devices, but I just get the same message. I'm only a fledgling AIX admin so I'm not sure what's keeping these devices "busy". Any input would be greatly appreciated.

Sincere thanks,
C.J.
