Membership
• A speci fi c resource can be a member of more than one managed set.
• The order in which members are added to, or appear in, a managed set does not affect the order
in which actions are performed on the set’s members.
• Performing actions on a large managed set (a set with many members) can take a long time. For
fl exibility, consider using several small managed sets rather than a single large set.
Managed sets of DR groups
Managed sets of DR groups require careful planning. Consider the following guidelines.
• Some DR group actions are permitted only on source DR groups; other actions are only permitted
only on destination DR groups. See using DR group actions .
• HP recommends that you create separate managed sets for source and destination DR groups.
When you conduct failover operations, you can perform the actions that correspond to the new
roles of the managed set.
• Source and destination DR groups (from different DR group pairs) can be members of the
same managed set.
• The source and destination DR group in a DR group pair cannot be members of the same
managed set.
• If you plan to use DR group managed sets for failover operations, ensure the managed sets are
controlled by the same management server at the time of failover.
Managed sets of virtual disks (or containers)
A managed set of the type virtual disks can contain two types of resources, either virtual disks or virtual
disk containers . The distinction between disks and containers is important when using managed sets.
See virtual disks overview
.
Managed sets of virtual disks (and containers) require careful planning. Consider the following guidelines.
General guidelines
• In general, do not include virtual disks and containers in the same managed set. Doing so can
result in errors when certain actions are applied to the set. For example, applying a replication
action to a managed set that includes containers will result in errors because containers cannot
be replicated.
• A managed set of virtual disks can include disks (or containers) from more than one storage
system.
• Ensure that you are aware of the current content of managed sets. When some GUI actions, job
commands, or CLUI commands are applied to a managed set, the members are converted from
virtual disks (storage volumes) to containers or from containers to a virtual disks.
