Today I noticed that the vSphere client to one of our Esxi 4.1 servers would not log in. So I SSH'd in and tried to restart the management services per this article: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1003490
However, both approaches are not working and produce the following errors:
[root@vm3 log]# service vmware-vpxa restart
vmware-vpxa: unrecognized service
[root@vm3 log]# /etc/init.d/hostd restart
-bash: /etc/init.d/hostd: No such file or directory
I have successfully used the same command on another ESXi 4.1 box as recently as last week, so I am at loss as to why this isn't working?
