symld write_disable should work.
I'm trying to unmap a device that I've moved to a new FA:port, but it is giving an error when I do the preview.  It is complaining that the device must be write disabled or not ready, but it is already marked write disabled (it is the R2 in an SRDF pair).  Has anyone seen this before?    The command file contains: unmap dev 00D3 from dir 7b:0;  # symconfigure -f unmap.1 -sid 123 preview Execute a symconfigure operation for symmetrix '000000000123' (y/ ) ? y  A Configuration Change operation is in progress.
