Hi everyone. We have recently migrated all of our mainframe data off of one of our DMX1000s, and I am attempting to reclaim the space. There are 400 ESCON devices that I'd like to delete, and have never done this before. I have unmapped and deleted non-ESCON devices, and am using the same procedure, but the results are not encouraging.

The ESCON devices are not masked, but they are mapped to the various EA ports. When attempting to unmap the devices, I get an error message telling me:

Validating configuration changes..........................Failed.

    Error occurred while Validating

    The lowest ESCON channel number should be divisible by 0x10

The file I'm using for symconfigure is:

unmap dev 0000 from dir ALL:ALL;

I've also tried this with putting in the director number and port number (3a:0) and gotten the same results. Any thoughts/ideas??? Thanks in advance!
