Overview
The EVM Storage View appears when you click Storage on the EVM navigation line. The page shows information about storage units that are available for replication on the StorageWorks subsystem.
Before running a job, you can use the EVM Storage View to review the storage units that are available. When a job calls for a unit that is not available, or that is not configured properly, the job cannot be run.
Before creating a job, you can use the EVM Network View to review the units that you can select and include in the job. When creating a job, you can only include properly configured units that appear in the EVM Storage View.

To view an active job's progress, click Monitor. The EVM Job Monitor page will appear.
New Job
To create an EVM job, click New Job. The Create EVM Job page will appear.

Notes
Storage units that are created by an EVM job are referred to as BCVs. These units are indicated by purple unit icons. BCV units cannot be used as the source for another EVM job.

None. The unit is not accessible to any host on the SAN.
All. The unit is accessible to all hosts on the SAN.
Connection Names. The unit is only accessible to the connections or named hosts that are listed.
Members. The individual disks that make up the storage unit are shown graphically. To see the disk identification number point to the member.
Clone? The message indicates whether or not the unit can be replicated by the clone method. To see an explanation of a NO message, point to NO.
Snapshot? The message indicates whether or not the unit can be replicated by the snapshot method. To see an explanation of a NO message, point to NO.
