In Oracle Solaris, the zone stateUnavailable, indicates thatthe zone is installed but cannot be booted. This state is displayed in theoutput of thezoneadm list -p command syntax.
root@initiator:~#zoneadm list -cp0:global:running:/::solaris:shared:-:none-:iscsi:unavailable:/iscsi:a0a4ba0d-9d6d-cf2c-cc42-f123a5e3ee11:solaris:excl:-:
An installed zone with shared storage resources can enter theUnavailable state if the zones framework experiences eitherfailures during the configuration of shared storage resources or failures duringZFS storage pool management.
To move the zone out of theUnavailable state, you mustfirst identify and possibly fix any problems related to shared storage resourceconnectivity or zone misconfiguration. You can then use thezoneadmattach command to reattach the zone properly and move it into theinstalled zone state. It is also possible to uninstall a zone with thezoneadm uninstall command to move the zone back into theconfigured zone state.
