Environment
Release : 20.3
Component : UIM - ADMIN_CONSOLE
Resolution
- The wasp on Primary Hub was rebuilt following the below document after which the issue was resolved:
How to reinstall the web-based Admin Console on the Primary hub (broadcom.com)
Note:
- The above technical guide solution assumes you don't have Operator Console installed on the same Primary Hub robot, i.e. you have Operator Console installed on a separate robot. In case you have Operator Console installed alongside Primary Hub on the same robot, redeploy the necessary Operator Console packages as well along with the packages mentioned in the above technical guide
Issue 2:
After following the above solution, ran into the following new error in the Admin Console:
HTTP STATUS 408
The request was not produced within the time that the server was prepared to wait.
Solution:
- Observed the Primary Hub's wasp directory (path: /opt/nimsoft/probes/service) had its permissions and the directory owner changed. The Owner was changed from "uim install user" to user "root" and the file permissions set as "rwx------" .
- Reverted the permissions and the owner of the directory to 'UIM installed user' following the below commands:
cd /opt
sudo chown uimadmin:uimadmin -R nimsoft
sudo chmod 755 -R nimsoft
- Restart wasp probe to resolve the issue
Note:
- in the above example:
(a) nimsoft is installed in its default location, i.e. /opt
(b) "uimadmin" is the UIM installed user
