An Exadata storage server physical disk on an X5 high-capacity full rack entered the predictive failure state.
Identify the two steps that you must perform to replace this failed physical disk.
A. Add the griddisks back into the ASM diskground they used to be a member of.
B. Create a new celldisk and new griddisks on the replaced physical disk.
C. Verify that the griddisks located on the physical disk have been successfully dropped from the associated ASM diskgroups.
D. Identify the griddisks located on the failed physical disk and drop them from the associated ASM diskgroups.
E. Replace the failed physical disk.
Correct Answer: CE
Explanation/Reference:
You may need to replace a physical disk because the disk is in warning – predictive failure status. The predictive failure status indicates that the physical disk will soon fail, and should be replaced at the earliest opportunity. The Oracle ASM disks associated with the grid disks on the physical drive are automatically dropped, and an Oracle ASM rebalance relocates the data from the predictively failed disk to other disks.
Note: After the physical disk is replaced, the grid disks and cell disks that existed on the previous disk in that slot are re-created on the new physical disk. If those grid disks were part of an Oracle ASM group, then they are added back to the disk group, and the data is rebalanced on them, based on the disk group redundancy and ASM_POWER_LIMIT parameter.
