VMware 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 multipathing software.
See Figure 71 (page

Risks

Single path failure may result in data loss or disk corruption.
