Troubleshooting
- Why am I being required to log in more than once by Power Center?
- Why can’t I access the Power Center management console from a Web browser, even though the Power Center server is running normally?
- Why was I automatically logged out of Power Center?
- Why did my connection to iDRAC6 devices (PowerEdge Servers) fail, when the network connection status is Connected?
- Why can’t Power Center receive events sent from devices?
- Why are previously-existing power policies (including EPR) still effective on devices when Power Center is corrupted or has been uninstalled?
- Why do I see the PostgreSQL error log "FATAL: terminating connection due to administrator command" in the Windows event log?
- Why I can’t open power center login page when I access it through Firefox 31?
- Why I encounter an error, “An internal error occurred. Contact the technical support for help: subordinate error code: 0x8f0c1301”, the Home page when OpenManage Power Center server is installed on SUSE Linux Enterprise Server 11 SP2?
- Why do I encounter a network exception while adding a LDAP user?
- Why do I encounter a network exception while adding a chassis to a group?
- In the compare report, why is the average power value of a device different when the service is stopped for a few hours?
- Why is the “policy return to normal” event not displayed when the only device in the Chassis Management Controller (CMC) is deleted?
- After discovering the devices, incorrect device information is displayed? Why is this happening?
- I am not able to view the power headroom graph on the home screen. How do I troubleshoot?
- I am not able to manage the servers discovered by OMPC through the Redfish protocol. Events are also not logged. How do I troubleshoot and resolve the issue?
