After several days investigation I`m going to rebuild array via PERC setup after restart. I removed all VMs to another machines. Solved.
 have a R330 (PERC H730) server with Raid10 (4 disks) array and one disk is probably broken. My OS (Debian 10) send me alert. Device: /dev/bus/0 [megaraid_disk_03] [SAT], 1 Currently unreadable (pending) sectors Device info:WDC WD40PURZ-85TTDY0, S/N:WD-WCC7K0NNF3J5, WWN:5-0014ee-2ba7065f6, FW:80.00A80, 4.00 TB Idrac8 in basic version is probably not able to rebuild array. What`s the best howto to replace failure disk and rebuild array witn new one? Install Openmanage in Debian and try it from the running OS?
