DFS2950A A CHECKPOINT REQUIRED TO SATISFY RESTART IS NOT AVAILABLE ON SYSTEM LOG

Explanation
 An attempt was made to start a subsystem, active or
tracker, but the checkpoint required to satisfy the request, usually
the cold start checkpoint, is not on the system log. This situation
can happen because PRILOG records were deleted from the RECON or from
remote takeover scenarios.

System action
 The restart is terminated and the system waits
for another restart command.

Programmer response
 Issue another restart command as appropriate.
