Unable to uninstall an ScaleIO deployment
Hi All,
I'm trying to uninstall a test ScaleIO system deployed on 3 ESXi host. I have followed the uninstall guidelines in ScaleIO deployment guide but during the uninstall process it fails with following error message.
{
"node": {
"ostype": "unknown",
"nodeName": null,
"nodeIPs": ["192.168.167.43"],
"domain": null,
"userName": null,
"password": null,
"liaPassword": "********"
},
"affectedEntities": [],
"commandID": "192.168.167.43<->9",
"untrustedCertificateThumbprint": null,
"commandState": "failed",
"startTime": "2018-02-18T09:43:47.586Z",
"completionTime": "2018-02-18T09:43:55.080Z",
"message": "Command failed: Could not connect to 192.168.167.43. Ensure that the relevant service is running and that the server can communicate with the node",
"result": null,
"weakDependencies": [],
"followingCommand": "None",
"targetEntityIdentifier": "192.168.167.43",
"allowedPhase": "query",
"commandName": ".NodeQueryCommand",
"archived": false,
"commandParameters": [],
"reportedEntityOpt": {
"present": false
}
}
I get same errors for all my ESXi hosts during uninstall query phase. Can someone help me out with this.
Thank you.

Hello,
The error you are receiving can mean a few things. It could mean that there is a connectivity issue between the ScaleIO Gateway and the server, it could mean that the LIA password that you are using in the ScaleIO Gateway is different then the install LIA password, it could mean that the LIA is not installed, or having issues, there may also be other meanings to this.
I would suggest looking into the ScaleIO Gateway trace logs to see if it shows more information about this error.
/opt/emc/scaleio/gateway/logs/scaleio-trace.log
Also ensure that the LIA is installed on the server by running this command:
rpm -qa |grep -i lia
You can try resetting the password on the LIAs to ensure you are using the correct password by doing the following:
vi /opt/emc/scaleio/lia/cfg/conf.txt
Edit the line "lia_token="
Delete the characters after the "=" and input the LIA password in plane text and save the file.
Then run "pkill lia", this will load and rehash the LIA password.
You can also just uninstall the ScaleIO components manually on each server with "rpm -e"
Hopefully this helps.
