How to resize a snapmirror volume?

Hi Everyone,

Can someone point me to instructions on how to resize a SnapMirror volume?

We have a 600Gb volume that we are mirroring from a FAS2020 in SiteA, to a FAS2020 in SiteB for backup.

Today I had to resize the primary volume in SiteA as it was running low on space. However, when I try to resize the mirror of this volume in SiteB it gives an error because the volume is "read only".

I've heard that the correct way of doing this is disabling the mirror, change the read-only state on the SiteB mirror via the command line, resize the volume, mark it read-only again and then restart SnapMirror - any ideas on how to actually achieve this would be great!

(and there I was thinking I'd quickly resize both volumes and "hey presto" everything would take care of itself! ).

Thanks,

Marc
