Requirements
•
Switch zoning or controller level SSP must be used to ensure each single path HBA has an
exclusive path to its LUNs.
•
Single path HBA server can be in the same fabric as servers with multiple HBAs.
•
Single path HBA server cannot share LUNs with any other 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 must be properly configured to work in a single HBA server configuration. The user is
required to:
◦ Download and extract the contents of the TAR file.
HBA configuration
•
Host 1 is a single path HBA host.
•
Host 2 is a multiple HBA host with multi-pathing software.
See Figure 53 (page 152) .
Risks
•
Single path failure may result in loss of data accessibility and loss of host data that has not
been written to storage.
•
Controller shutdown results in loss of data accessibility and loss of host data that has not been
written to storage.
NOTE: For additional risks, see Table 59 (page 159) .
