Several clients are accessing an ONTAP SnapMirror DP destination volume. Some clients frequently access the newest SnapMirror volume data. Accessing this data is much slower when compared to clients that directly access data on the source. You use the wafl scan status command against the destination.
What is a symptom of the problem in this scenario?
A . blocks used summary update
B . active bitmap rearrangement
C . container block reclamation
D . volume deswizzling
Answer: D
Explanation:
In the scenario described, where clients are experiencing slower access to the newest data on an ONTAP SnapMirror Data Protection (DP) destination volume compared to direct access on the source, and considering the use of the wafl scan status command against the destination, a likely symptom of the problem could be:
volume deswizzling – Deswizzling is a process that occurs when data is read from a SnapMirror destination volume. In a SnapMirror relationship, data is stored in a "swizzled" format, which is efficient for replication but needs to be converted ("deswizzled") back for regular access. If a lot of deswizzling is happening, it could contribute to slower access times for clients accessing the newest data on the destination volume.
