Create Replicated Mirror Group Wizard: Configure storage systems

Use this page to configure one or more storage systems to use replicated mirror groups.

The wizard provides this page only when you have a storage type that requires you to configure the corresponding storage system.

You can configure storage systems only for IBM® DS-Series Metro Mirror (In-band), IBM DS-Series Global Mirror, IBM System Storage® SAN Volume Controller (SVC), and IBM XIV® storage types. Hitachi/HP Universal Replicator and EMC Symmetrix do not require the configuration of storage systems.

The amount and type of information that you need to provide vary based on the storage type of the storage system.

A storage system represents the storage unit or storage controller that hosts or controls one or more disks or volumes to be replicated in the mirror group. An example of a storage system is a DS8800 or SAN Volume Controller (SVC) cluster. Every storage system has a vendor-specific unique identifier. For example, a DS8300 storage system might have a unique identifier of IBM.2107-1300851.

Fields

Name

Specify a name for an independent unit of enterprise storage that can provide all required enterprise-level storage functions. Enterprise storage system names include storage units such as Redundant Array of Independent Disks (RAID) or FlashCopy FlashCopy® products.

Note: start of changeIf predefined storage systems are available, you can select one to configure it. If you select an existing storage system, the wizard provides the necessary information for the remaining properties, which you cannot edit. If you manually specify a name, you also must manually specify information for those properties.end of change

start of changeIP addressesend of change
start of changeSpecify the IP address or addresses, if necessary, of the storage system that interacts with host systems. This property is available only for the SAN Volume Controller (SVC) storage type. For SVC, you can specify either one or two IP addresses.end of change

start of changeSelect the appropriate storage identifier of the storage system for which you are configuring the replicated mirror group. The format of the storage identifier varies based on the type of storage system that you selected to configure. The list contains those storage systems of the appropriate type that meet all prerequisites for being available to manage in PowerHA SystemMirror.end of change
Storage agents
Select one or more storage agents from the list of storage agents that are defined for the cluster. Storage agents are available only for IBM DS-Series Global Mirror and IBM XIV storage types.

Actions

Add Another
Click Add Another to add another set of fields so that you can configure another storage system. All fields for the added storage system are inactive until you specify information for the Storage system name field.
Remove
Click Remove to remove the content from the first set of storage system fields and disable all fields after the Storage system name field. If applied to an added storage system on the page, this action removes the entire set of fields for the added storage system.
