OpenVMS 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.
•
Host 2 is a dual HBA host.
See
Figure 37
.
Risks
•
For nonclustered nodes with a single path HBA, a path failure from the HBA to the SAN switch
will result in a loss of connection with storage devices.
NOTE:
For additional risks, see
Table 30
on page 125.
Limitations
•
HP Continuous Access EVA is not supported with single path configurations.
