I have a test environment for Oracle single instance on ASM 18.104.22.168.
I have restored database from tape and during the recovery, the system crashed by some I/O error.
I restarted the server, mounted the database and run validate on archivelog(thinking that the blocks in this archivelog may be corrupted)
RMAN> validate archivelog sequence=2994; RMAN-03009: failure of validate command on ORA_DISK_1 channel at 02/25/2014 12:24:13 ORA-19501: read error on file "+DATA01/crimesys/archivelog/2014_02_24/thread_1_seq_2994.294.8 ORA-15081: failed to submit an I/O operation to a disk ORA-15081: failed to submit an I/O operation to a disk
And the system crushed again.
Note: Other validates are successful just this archivelog causes the system crash.

How to solve? Is the virtual block corrupted? How to check? Please help.
