HP EVA P6000 Storage - Manual (Page 157)

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 79 (page 158) .
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 “OpenVMS” (page 165) .
