What Is MirrorView/A?
4-23
Data Replication and Data Mobility Software
Since MirrorView/A uses the reserve LUN pool, you need the
following information for system setup so you can bind LUNs for the
reserved LUN pool. The number of reserved LUNs should always be
twice the number of source LUNs. A MirrorView/A primary image
LUN is a source LUN. Note that SnapView and incremental SAN
Copy also use the reserved LUN pool. One application can use a
reserved LUN as long as another application is not using it.
