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: 9.40.12.0) 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?
BWC must be configured and battery must be charged before expanding it on a fly.
Also, backup data first and then try to expand the array.
