Woah, 3 (three!) posts in one day… I’ve put up a new version of my check_3ware script.
And again, no thanks to me but to Simon Deziel and Stas (Станислав) for reporting a bug, sending in a patch, and a feature request. Now check_3ware will not issue a warning when an array is in verifying state.
I didn’t test the script since I do not have any 3ware hardware anymore, so get it here and use it at your own risk ;-)
