There's HP DL180G6 Server with HP Smart Array P410 controller. Server running MySQL on Debian Linux with ext4 fs. HPACUCLI utilities (ACU CLI Version: 220.127.116.11) are installed.
There's 4 HDD Seagate 600GB in RAID 10 array. I want add 2 more HDDs to this array and expand it without data loss, reinstalling all and downtiming server. Can this be done such way?
