Case:
A IBM DS3400 server, 12*300G RAID5, the operating system is RHEL5, no heat set, and there are 3 LUNs on the storage. Two of them are LUN where the Oracle production database of the ERP system is located, and the other is the other.LUN where the Oracle database backup file is located.Because the two disks are offline, RAID crashes and the data is lost.After detecting the hard disk, a large number of bad sectors were found in many hard disks.
