“‘/sbin/ifup vswif0’ suceeded, but returned with non-zero status: 1” on ESX Service Console


When trying to configure the IP address or enable a Service Console the following error may appear:

# esxcfg-vswif -e vswif0
Error trying to perform operation Exec of command ‘/sbin/ifup vswif0’ suceeded, but returned with non-zero status: 1

In addition the ip address is listed as

# esxcfg-vswif -l
Name Port Group IP Address Netmask Broadcast Enabled DHCP
vswif0 Service Console true false


This results from an IP address conflict:

– Bind another IP address on the same subnet to the the service console:

# esxcfg-vswif -i -n vswif0

– Ping the conflicting IP address:

# ping
PING ( 56(84) bytes of data.
64 bytes from icmp_seq=0 ttl=128 time=1.36 ms
64 bytes from icmp_seq=1 ttl=128 time=0.278 ms

rtt min/avg/max/mdev = 0.278/0.517/1.361/0.379 ms, pipe 2

– Check the ARP table:

# arp -a
server.domain.com ( at 00:99:99:99:99:99 [ether] on vswif0

00:99:99:99:99:99 is the MAC of the conflicting server.

Host in HA Cluster must have userworld swap enabled

Posted on by .

Error when enabling HA on ESX 3.5 i servers : Host in HA Cluster must have userworld swap enabled

This error you get from a lack of storage reservation for saving the HA settings on the ESX3.5i. You can set this using the following procedure.

To enable swap on your ESXi 3 host system:
  1. On the VirtualCenter Server, select the ESXi 3 Server host.
  2. Click the Configuration tab.
  3. Click Advanced Settings.
  4. Choose ScratchConfig.
  5. Configure ScratchConfig.ConfiguredScratchLocation to a valid directory with sufficient space (1GB) to hold the userworld swap file. The userworld swap can be configured on local storage or shared storage.

    Note: Each swapfile needs a unique name across all ESX hosts.

    For example, /vmfs/volumes/.

  6. Select the ScratchConfig.ConfiguredSwapState option.
  7. Click OK.
  8. Reboot the ESX Server 3i system.
After you have enabled swap on the ESXi 3 host system, you can add the host to a VMware HA cluster.
