3.Configurethezone(s)

Sincethev1280appservzone isalreadycreated,we justneedtoconnect thezoneto thepool thatwe justcreated.

Usezonecfgtoupdatethezoneconfiguration.



%zonecfgzv1280appserv

zonecfg:v1280appserv>setpool=appservpool

zonecfg:v1280appserv>verify

zonecfg:v1280appserv>exit

Ifthezoneisnotcreatedyet,followtheinstructionsofZonecreationfordummies,andspecifythepool,whenthe

zoneisconfigured.

4.Rebootthezone

Simplyrebootthezone,v1280appserv,soitbindstothenewlycreatedpool,whenitcomesback.

Troubleshooting:



Ifyouencounterthefollowingerror,doublecheckyourconfiguration.

pooladm:configurationat'/etc/pooladm.conf'cannotbeinstantiatedoncurrentsystem

It is very likely that you configured some resource that is either not available or beyond its limits, on thesystem.
