Instruction Manual

• An EVA storage system can present LUNs to iSCSI Initiators and Fibre Channel hosts concurrently.
HP StorageWorks EVA storage system software
An EVA LUN that has been presented to an iSCSI initiator is supported with EVA storage applications
such as HP StorageWorks Continuous Access, Business Copy, SSSU, and Replication Solutions
Manager. There are some restrictions with iSCSI hosts when using the EVA iSCSI connectivity option,
as described in the following sections.
Supported features for iSCSI hosts
For HP StorageWorks Business Copy, iSCSI hosts are supported with the following basic Business
Copy features:
• Snapshots of LUNs presented to iSCSI hosts
• Snapclones (normal or 3-phase) of LUNs presented to iSCSI hosts
• Instant Restore from snapclone to original source
• iSCSI hosts can access and write to EVA snapshots
• iSCSI hosts can access and write to EVA snapclones
• HP Command View, SSSU, or RSM can be used to create snapshots manually or automatically
on a schedule using RSM
• CLI support to enter replication commands from iSCSI hosts
Features not supported for iSCSI hosts
Advanced replication features for LUNs presented to iSCSI hosts through the mpx100 that require a
host agent on the iSCSI Initiator are not supported, as there are currently no iSCSI replication host
agents available. The following features are not supported:
• Mounting and unmounting LUNs via a host agent. Mounting and unmounting LUNs must be done
manually
• Accessing the host's view of the storage, such as viewing an F drive drive from a host
• Deploying host agents to allow customers to launch a script on the iSCSI host
Table 8 lists the support available for EVA storage system software when using the EVA iSCSI
connectivity option.
