Author: sbruno Date: Wed Apr 10 23:37:15 2013 New Revision: 249350 URL: http://svnweb.freebsd.org/changeset/base/249350 Log: Update ciss(4) man page. We absolutely support performant mode of operation on this controller. Indicate that the 5300 is the *only* controller that will only work in simple mode. Bus rescans should not be needed now and I consider it a bug if disks do not appear or dissapear when created or destroyed. Obtained from: Yahoo!
