To check

stmfadm list-lu -v

you can change properties with stmfadm modify-lu

I'm not sure of the exact syntax, so check the man page.





I've followed this thread, since it is in my line of work.

I'd be interested to know the progress of this. Are you guys still having this problem?

And about the setup:

The hosts seem to be windows, right? Have you seen this problem with other host OS's? Are they windows on hardware, or windows VM's? If VM's, which hypervisor and are the LU's presented directly to the VM's or through the hypervisor? Do you use NPIV? Other interesting information?

Regards Johan
