Removing a Network Adapter from a vSwitch

[msemon1]

Hello,

I am trying to remove a network adapter from a virtual switch on an ESXi 4. host. When I go under the properties of the vSwitch -----> Network Adapters

and click remove I get an error that says:

Call "HostNetworkSystem.UpdatePortGroup" for object "networkSystem-1133" on vCenter Server "Our vCenter Server Name" failed.
Operation failed, diagnostics report: Error interacting with configuration file /etc/vmware/esx.conf: Write failed during Unlock. 
This is likely due to a full or read-only filesystem.  Original Error was: Error interacting with configuration file /etc/vmware/esx.conf:
Unable to write to file /etc/vmware/esx.conf.umBSCD while saving /etc/vmware/esx.conf operation aborted.  It is likely this was caused by a Full Disk.

I checked the storage and there is plenty of space on the storage so I don't think this is the problem.  I am wondering if this must be done while host is powered off or done from a command line with CLI. The CLI command appears to be:

vicfg-vswitch [<connection_options>]

--del-dvp-uplink <adapter_name> --dvp <DVPort_id> <dvswitch_name>

The reason I am removing the adapter is it is in a down state since it has not been connected to a switch yet.

Thanks,

Mike

This doesn't need to happen while offline.

Are you sure that the partition hosting ESXi isn't full? (not the shared storage - ESXi itself).  Login to the Tech Support Mode and give us the output of 'df -k'

Also, this can happen if the filesystem is write protected due to failure....have you considered a reboot to see if it comes back.

Here is the output from df -k. Looks like there is still space.

I wonder if the esx.cfg file is corrupt or some data is missing from the file? Have a look at the file. I would also look at the other esx.cfg.xxx that is referenced in the error. I believe that will be a temporary copy of the file.

See if the following might help fix the issue if the esx.cfg file is broken. http://kb.vmware.com/kb/1004451

Thanks for everyone's suggestions. I will try to rebuild the esx.cfg file

Hello,

Is this a dvSwitch or regular vSwitch? The commands for each are slightly different.

If you have host profiles capability you can rebuild the esx.cfg from the hostprofile.

I would also restart hostd on your ESXi host. It sounds like ESX and vCenter are out of sync. Then I would also restart vCenter as well as refresh your network settings. I have had this happen with storage and it finally took me going into the vCenter db to remove some 'no longer' in use storage elements.

I think you hit the nail on the head.  This host has a regular vSwitch. The services have been restarted, however, I think there is a problem

with the host profile. I believe this server may have been built incorrectly with the host profile. Will try to find more information on how this host

was built.
