HP StorageWorks Continuous Access EVA Administrator Guide (T3687-96043, December 2005)

database resides on that array. Instructions for its use can be found in the H P StorageWorks Command
View EV A Online Help.
To use HP Continuous Access EVA you must first use HP Command View EVA to:
• Ad d licenses
• Initialize controllers–This process binds the controllers together as an operational pair and
establishes the firstdiskgrouponthediskarray.
• C reate disk groups–A disk group is a set of physical disks from which storage pools are created.
When an array is initialized, a default disk group is created. If you are per forming bidirectional
replication, the disk groups should be symmetric with respect to capacity on both arrays.
• Create host definitions–The host connects to dual fabrics through a pair of host bus adapters
(HBA) and accesses storage throug h the array controller. C reating hosts in HP Command View
EVA defines a path from a controller to at least one HBA.
• C reate virtual disks–A virtual disk is variable disk capacity that is defined and managed by
the array controller and presentable to hosts as a disk. You can assign a combination of
characteristics to a virtual disk, such as a name, redundancy level, size, and other performance
characteristics.
• Present virtual disks to hosts–Assigning a virtual disk to a host results in a host presentation. You
can present a virtual disk when you create it, or wait until later. The virtual disk must be presented
toahostbeforeitcanbeusedforreplication.
NOTE:
You can present a virtual disk to a predefined but nonexistent host; for example, NULL_HOST with
a WWN of all zeros.
HP Replication Solutions Manager tasks
HP Replic ation Solutions M anager is an interactive, visual environment for managing data replication.
After you create hosts, virtual disks and their presentations, and your hosts can access your virtual
disks, you are ready to replicate data using HP Replication Solutions Manager. Additional operational
information is in the online help system.
HP recommends that you use the replication manager to:
• C reate and delete DR groups.
• Cha n ge properties for DR groups.
• Add and remove members from DR groups.
• Failover, suspend, resume, and change failsafe mode by DR group.
• C reate and delete mana ge d sets.
• Fail over, suspend, resume, enable and change failsafe mod e, and revert to Home by managed
set.
• Direct commands to the appropriate array re gardless of selected array.
• Actively monitor arrays (copy, failsafe, logging, merging).
• Create and restore configuration d atabases for m anag ed sets and jobs.
