Pool member in High Availability deployment is grey

The status of a pool member (for example Primary Polling Engine) in the HA Deployment Summary shows GREY, instead of GREEN. In Registry Editor, make sure that the value for InstallType and RunType is MainPoller, MainPollerStandby, AdditionalPoller, or AdditionalPollerStandby, as appropriate. If not, change the values.

  2. RunType

Product section

Orion Platform

Cause

The Orion Installer incorrectly initializes the RunType value in the registry.

Resolution

  1. Stop the HA service in Windows.msc on both servers in effected HA pool.
  2. Launch the Registry Editor on the server with the issue.
    For example, type run into the Windows search field, and enter regedit.
  3. Navigate to HKEY_LOCAL_MACHINE > SOFTWARE > Wow6432Node > SolarWinds > High Availability.
  4. Make sure the value for InstallType and RunType is correct. If not, double-click the value and change it as follows:
    • On the active primary polling engine, both InstallType and RunType values must be MainPoller.
    • On the standby primary polling engine, both InstallType and RunType values must be MainPollerStandby.
    • On an active additional polling engine, both InstallType and RunType values must be AdditionalPoller.
    • On a standby additional polling engine, both InstallType and RunType values must be AdditionalPollerStandby.
  5. Re-enable HA service on both servers. Start with the server that is currently active.
  6. Open the High Availability Deployment Summary page. The pool member is now up (green).

Alternative way to verify that this is your issue (using SWIS) 

To verify in the database that the server is not in the HA_PoolMembers table:

  1. Open <orion server IP>/orion/admin/swis.aspx in your browser.
  2. In the Select entity drop-down, select Orion.HA.PoolMembers.
  3. Make sure the entry field below Select entity is empty.
  4. Select Generate Select Query, and click Execute Query.

If you cannot see the pool member in the results table, this is your issue.

 

Alternative way to verify that you have fixed the issue 

Now you can verify that the server exists in the Database Manager:

  1. Start the Database Manager.
  2. Add the default Server.
  3. Navigate to the HA_PoolMembers table, right-click it and select Query table
  4. Click Execute query.
  5. Make sure the server exists. Verify that in PoolMemberType, there is both MainPoller and MainPoller Standby, both AdditionalPoller and AdditionalPollerStandby.
