Hba Configuration; Risks; Limitations; Linux (Itanium) Configuration - HP EVA P6000 User Manual

HBA configuration

Host 1 is a single path HBA.
Host 2 is a dual HBA host with multipathing software.
See Figure 68 (page

Risks

Single path failure may result in data loss or disk corruption.
NOTE: For additional risks, see

Limitations

HP P6000 Continuous Access is not supported with single path configurations.
Single HBA path at the host server is not part of a cluster, unless in a Linux High Availability
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.
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
