Konfigurace HW RAIDu na serveru SunFire T2000

Napsat komentář

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.

Zjištění současného stavu

root@srv-01 # raidctl

Controller: 0
        Volume:c0t0d0
        Disk: 0.0.0
        Disk: 0.1.0
        Disk: 0.2.0
        Disk: 0.3.0


root@srv-01 # raidctl -S

0 "LSI_1064E"
c0t0d0 2 0.0.0 0.1.0 1 OPTIMAL
0.0.0 GOOD
0.1.0 GOOD
0.2.0 GOOD
0.3.0 GOOD

root@srv-01 # raidctl -l c0t0d0

Volume                  Size    Stripe  Status   Cache  RAID
        Sub                     Size                    Level
                Disk
----------------------------------------------------------------
c0t0d0                  68.3G   N/A     OPTIMAL  N/A    RAID1
                0.0.0   68.3G           GOOD
                0.1.0   68.3G           GOOD

Vytvoření RAID 1 z disků c0t2d0 a c0t3d0

root@srv-01 # raidctl -c c0t2d0 c0t3d0

Creating RAID volume will destroy all data on spare space of member disks, proceed (yes/no)? yes
Volume c0t2d0 is created successfully!
