“‘/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

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.

HA error on all ESX servers

Posted on by .

A customer had 17 ESX servers in stress, after a thermal error 3 blades went off line and disk 0 was gone. HA gave an error on all servers and reconfigure HA didn’t do the job.

An error occurred during configuration of the HA Agent on the host was the error. I disabled HA on the cluster and enabled it, afther this action ervy server was back online and no error’s. I suppose that the setting that only 2 servers can fail for HA was course of this error, 3 servers went down at the same time and VMware ESX did’t see the old servers online therefor it was not allowed to reconfigure the hosts for HA. Disable HA and enabling HA pushes an new HA settings set to the ESX servers and makes it possible to reconfigure it for HA.
