Logical unit presentation

Edit online

A volume must be explicitly presented to a host before it can be used for I/O operations.

The system supports LUN masking on an HP EVA controller. When the system presents a volume, the LUN can be specified or allowed to default to the next available value.

The system supports LUN virtualization on an HP EVA controller. The LUN-host relationship is set on a per-host basis.

Note: All nodes and ports in the system must be represented as one host to the HP EVA.

Special LUs

The Console LU is a special volume that represents the SCSI target device. It is presented to all hosts as LUN 0.
