# Fallback message strings in en-US DATA localizedData { # same as culture = "en-US" ConvertFrom-StringData @' PacketDirectMustUseHyperVPort=Using Enable Packet Redirect on the SET team must use Hyper-V Port mode as the load balancing algorightm. This will reset the LB mode. NoHyperVModule=Hyper-V PowerShell Module not found. CheckSETMembers=Checking if SET network adapter members match or not. TeamMembersUpdate=SET Network Adapter members mismatch. This will be updated. LBUpdate=SET load balancing mode is different. It will be updated. TeamingModeUpdate=SET teaming mode is differet. It will be updated. UpdatingSETeam=Updating SET configuration as requested. UpdateAllowManagementOS=Updating AllowManagementOS on the VM switch associated with the SET. IOVcannotbeUpdated=EnableIOV cannot be updated once SET is created. Ignoring this change in configuration. ReservationModeCannotBeUpdated=Reservation mode cannot be updated once SET is created. Ignoring this change in configuration. PacketDirectCannotBeUpdated=Packet Direct cannot be updated once SET is created. Ignoring this change in configuration. CheckNetAdapter=Checking if network adapter specified is a part of another VM switch. SwitchWithNameExists=Another switch with specified name already exists. It is not recommeded to use the same name for mulitple switches. UsedAdapter=One of the adapters in the specified SET configuration is being used in another switch. CreateSET=Creating SwitchEmbeddedTeam. UpdateSET=Updating SwitchEmbeddedTeam. RemoveSET=Removing SwitchEmbeddedTeam. CheckSwitchExists=Checking if SET already exists. SETMembersDontMatch=SET members don't match. This team will be updated. CheckSETIOV=Checking if IOV is enabled. CheckSETReservationMode=Checking if reservation mode is configured as desired. CheckSETEnablePacketDirect=Checking if packet direct is enabled. CheckSETLoadBalacing=Checking if load balancing mode is configured as desired. CheckSETTeamingMode=Checking if SET teaming mode is configured as desired. SwitchConfigPresentNoAction=Switch configuration present as desired. No action needed. SwitchPresentRemove=Switch team is present while it should not. It will be removed. SwitchNotPresentCreate=Switch team does not exist. It will be created. SwitchNotPresentNoAction=Switch team exists. No action needed. SwitchNotPresent=Switch is not present. CheckSETAllowManagementOS=Checking if AllowManagementOS configurtion is present.
