HP 4000.6000.8000 Enterprise Virtual Arrays - Manual (Page 156)

Limitations
•
HP P6000 Continuous Access is not supported with single path configurations.
•
Single path HBA server is not part of a cluster.
•
Booting from the SAN is supported on single path HBA servers.

Requirements
•
Switch zoning or controller level SSP must be used to ensure each single path HBA has an
exclusive path to its LUNs.
•
Single path HBA server can be in the same fabric as servers with multiple HBAs.
•
Single path HBA server cannot share LUNs with any other HBAs.
•
In the use of snapshots and snapclones, the source virtual disk and all associated snapshots
and snapclones must be presented to the single path hosts that are zoned with the same
controller. In the case of snapclones, after the cloning process has completed and the clone
becomes an ordinary virtual disk, you may present that virtual disk as you would any other
ordinary virtual disk.
•
HBA must be properly configured to work in a single HBA server configuration. The single
path adapter driver from the AIX 2.0B EVA Kit should be installed: PC1000.image.
HBA configuration
•
Host 1 is a single path HBA host.
•
Host 2 is a dual HBA host with multi-pathing software.
