New Revision: 255043
URL: http://svnweb.freebsd.org/changeset/base/255043
Log:
Bump up the default timeouts for move commands in the ch(4) driver
to 15 minutes, and 5 minutes for things like READ ELEMENT STATUS.
This is needed to account for the worst case scenarios on at least
some Spectra Logic tape libraries.
