User guide

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 single HBA host with Tru64.
• Host 2 is a dual HBA host.
See Figure 36 (page 124).
Risks
• For nonclustered nodes with a single HBA, a path failure from the HBA to the SAN switch will
result in a loss of connection with storage devices.
• If a host crashes or experiences a power failure, or if the path is interrupted, data will be lost.
Upon re-establishment of the path, a retransmit can be performed to recover whatever data
may have been lost during the outage. The option to retransmit data after interruption is
application-dependent.
NOTE: For additional risks, see “OpenVMS and Tru64 UNIX failure scenarios” (page 133).
