DR group write history log
The DR group write history log is a virtual disk that stores a DR group's host write data. The log is
created when you create the DR group. Once the log is created, it cannot be moved. For more
information, see “Planning for DR group write history logs” (page 42).
Managed sets
Managed sets are a feature of HP P6000 Replication Solutions Manager. A managed set is a
named collection of resources banded together for convenient management. A managed set can
contain DR groups, enabled hosts, host volumes, storage systems, or virtual disks.
Performing an action on a managed set performs the action on all members of the set. For example,
the managed set Sales_Disks might include two virtual disks, West_Sales and East_Sales. If you
perform the New Snapshot action on the managed set Sales_Disks, the interface creates a new
snapshot of West_Sales and a new snapshot of East_Sales.
