There is a simple rule for device masking on a VMax  The IG/PG/SG component combination for a specific device (any device) must be unique.  So if you have a MV with IG = HBA1 PG = FA1 SG = device 100  and you create a new MV2 with IG2 = HBA1,HBA2 PG2 = FA1, FA2 SG2 = device 100  This will fail as the HBA1/FA1/device 100 combination is non unique.  Now this may be a failure of the mismatch between the first and second Views - or it may be a failure between a third view and the second view.  So firstly you need to identify which Views the device is in currently and then see if there are any combinations (as above) that would prevent it from being in the 'second' view.

hi, i have a tdev 0100 in a storage group SG_1 which is in a view V_view1  and i want to move it to antother storage group SG_2 which is in another view V_view2  i test all the above commands : # symaccess -sid xx -name SG_2 -type storage add dev 0100 #symsg -sid xx -sg SG_2 add dev 0100 #symsg -sid xx -sg SG_1 move dev 0100 SG_2  and the result for all those commands is the message:  "the operation cannot proceed because one or more device(s) is already masked within a view"  but a device can belongs to many storage group ?  VMAX SE version: 7.3.2.2  what did i miss or that i forgot ?  thanks for you reply
add a TDEV to another storage group
