Before you insert a SAS-2 component into the chassis, you must upgrade the firmware of your SAS-1 components (SAS-1 NEMs and storage modules) to a firmware version that supports SAS-1/SAS-2 coexistence.
At a minimum, all SAS expanders for SAS-1 NEMs and Sun Blade 6000 storage modules must be upgraded to firmware revision 5.04.03 (or later). This firmware revision enables SAS-1/SAS-2 devices to coexist in the Sun Blade 6000 modular system chassis. Using older firmware revisions might result in SAS-2 devices hanging.
