Poweredge T110 Server, the RAID 5 is failed as attachemnt, the server cannot boot now, how to rebuild? thanks for your help.
See if in any of the menus it says anything about foreign configurations, if so, then import it. If there is no such option, you may need to try to force online disk 1. Backups are your next option after that.
Finally, replace all 3 harddisk, rebuild RAID5, restore from full backup, done. thanks.
