Can I map/mask celerra devices on backend Symm to different FA online ?

Hi,

Yes, You can always map the existing devices to another FA port online.. So that you can access the same device from two different paths..

But if want to remove it from 1 st FA port and map it to another then your host wont be able to see the device through first path. So its disruptive.. and cannot be done online.

My question is similar to this one which has just been answered.

In theory I should be able to to do this non-disruptively as long as there is more than one FA which sees the devices. In our case we currently have (8) FAs in our Celerra VG8 Masking view. I'd like to replace (3) of these paths with (3) new FAs. So basically I should be able to do the following:

1) zone the (3) new FAs in same fashion as the old ones

2) Edit existing IG removing (3) old FAs and add (3) new FAs

Do we need to rescan the buses?

So again in theory this should suffice, however finicky as the Celerra may be, how would it behave losing (3) paths and gaining (3) new ones , while still having the original untouched (5) paths of (8).

You should work with your local customer service team on this – AFAIK the SCSI chains the data mover uses are not dynamic and probably need manual cleanup

Rainer thanks for the reply. I also received a reply from EMC support which tells us of the feasibility and possibility of their engagement f required.

Thanks,
