Article ID: MM0064 Backup job fails to acquire data path with sufficient spare media for data

Symptom

Backup job fails with

Error Code [62:81] There are no disk paths that are enabled and with the required space.

Cause

Primary cause is insufficent spare media.  Secondary causes can be

  • Insuffient streams available to associated storage policy
  • Max number of data transfers has been exceeded
  • Optimized for concurrent LAN not enabled.
  • CVMountd service hung on MediaAgent

Resolution

Check the following:

  • Associated Storage Policy Primary copy has sufficient spare media exists and is accessible for target library.
  • Subclient Number of data readers is less than the associated storage policy's Number of Device Streams and mulitplexing factor (if enabled). 
  • Subclient Number of data readers is less than the target disk libraries max number of writers.
  • MediaAgent's Max number of parallel data transfers is sufficient for requested subclient streams and concurrent jobs using same MediaAgent.
  • If using a tape library and sufficient available device streams exist, restart MediAgent services to clear hung CVMountd service.
