Hba Configuration; Risks; Limitations; Linux (32-Bit) Configuration - HP StorageWorks 6400/8400 - Enterprise Virtual Array User Manual

• 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 39.

Risks

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

Limitations

• HP Continuous Access EVA 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.
