Před nějakou dobou (v roce 2008) jsem stál před problémem, jak dokonfigurovat HW RAID na serveru SunFire T2000 s OS Solaris 10. O tom, jak se mi to povedlo, jsem se rozhodl podělit.
Původní stav byl dva 72GB disky c0t0d0 a c0t1d0 v RAID 1 jako c0t0d0. Mým cílem bylo ze zbývajících dvou disků c0t2d0 a c0t3d0 vytvořit také RAID 1.
