Are you using MirrorView/A or MirrorView/S?  As well as Glen's comment, please note that MirrorView/A only allows for one secondary image per primary image. MirrorView/S supports two secondary images per primary, but only one to one if consistency groups are used.
Production primary CX500(2.26.500.5.014)-LUN already mirrorviewed to DR-CX310, now add another secondary image MV to VNX5300(05.31.000.5.509), there has error (0x7105823c) while click to synchronize. The error message as attached. I just want to make one more new secondary image to VNX5300 but sync error. Is there any limitation to perform this task? 
Failed synchronization the secondary mirror image (0x7105823c)
