SQL server crashed due to HP MPIO issue

We migrate our system to HP dl980 with windows cluster recently. At first, I found some IO errors when restore production database to a standby server. We encountered a critical issue(disk missing) when backing up database directly to disk in 8/11. Any information will be appreciated. (Please see attachment for full text)
