How long will a Copy Back operation take when a hot spare is invoked?
A.
Pro-Active hot spare does not use a Copy Back operation
B.
Copy Back time depends on the RAID type
C.
Copy Back time depends on the disk capacity
D.
Copy Back time depends on the disk type
Explanation:
Note: Starting with Release 24, you can now use a proactive hot spare for proactive disk replacement. Before
Release 24 you had to remove the physical disk to replace in order to force a rebuild. During the rebuild phase,
the RAID group was “degraded” and at risk.
Resolution:
Three main benefits of using a proactive hot spare:
Avoiding “uncorrectable errors” due to media problems during the rebuild process.
Greatly reduce the risk of having a degraded RAID group, and the risk of having a double-faulted RAID
group.
Performance – a copy to hot spare is faster than a normal rebuild.
