Limitations

• HP P6000 Continuous Access is not supported with single path configurations.

7 Controller A3 Host 2

8 Controller B4 Management server

Linux (32-bit) configuration

Requirements

• Switch zoning or controller level SSP must be used to ensure each single path HBA has an

exclusive path to its LUNs.

• All nodes with direct connection to a disk must have the same access paths available to them.

• Single path HBA server can be in the same fabric as servers with multiple 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 configuration

• Host 1 is a single path HBA.

• Host 2 is a dual HBA host with multi-pathing software.

See Figure 38 (page 127).
