Specifies the fabric name in this VSAN, and will use a
zero-length octet string as default value if not configured.
The fabric name specified here takes effect only if the
value of hpnicfVsanDmDomainConfigureEnable is 'false', and the
same fabric name should be configured for all switches in
this VSAN.
If the value of hpnicfVsanDmDomainConfigureEnable is 'true',
the principal switch WWN is used as fabric name.
The value should be set to zero-length when canceling
a configured fabric name.
