Identify two valid reasons for executing an X5 Exadata storage server rescue procedure.
A.
Accidental loss of all data from all griddisks in a storage server
B.
Corruption in the /(root) filesystem
C.
Corruption in a normal or high redundancy ASM diskgroup
D.
The failure of both physical disks 0 and 1
E.
Only the failure of physical disk 1
F.
Only the failure of physical disk 0
Explanation:
The rescue procedure is necessary when system disks fail, the operating system has a corrupt file system, or there was damage to the boot area. If only one system disk fails, then use CellCLI commands to recover. In the rare event that both system disks fail simultaneously, you must use the Exadata Storage Server rescue functionality provided on the Oracle Exadata Storage Server Software CELLBOOT USB flash drive.
Incorrect Answers:E, F: If only one system disk fails, then use CellCLI commands to recover.
