becomes an ordinary virtual disk, you may present that virtual disk as you would any other
ordinary virtual disk.

Linux 64-bit servers can support up to14 single or dual path HBAs per server. Switch zoning
and SSP are required to isolate the LUNs presented to each HBA from each other.

HBA configuration

Host 1 and 2 are single path HBA hosts.

Host 3 is a dual HBA host with multi-pathing software.

See

Figure 39 (page 128)

.

Risks

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

NOTE:

For additional risks, see

“Linux failure scenarios” (page 133)

.

Limitations

HP P6000 Continuous Access 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.
