IT44052: CTGGA2406 THERE ARE NO ACTIVE STORAGE STREAMS ALL ACTIVE VMS ARE IN INITIAL STAGE OR WAITING FOR AVAILABLE STREAMS.

APAR status

• Closed as program error.

Error description

• After IBM Storage Protect Plus appliance reboot, if many jobs
  are starting at the same time, backups can fail with :
  INFO,...,CTGGA3110,Hypervisor VM Backup Progress: Queued(4)
  Active(0) Dequeued(0)
  INFO,...,CTGGA2406,There are no active storage streams  all
  active vms are in initial stage or waiting for available
  streams.
  
  The jobs are hung waiting to open the VM guests disks, this uses
  up all VADP streams available for backups.

Problem conclusion

• Before IBM Spectrum Protect Plus level 10.1.15, when the opening
  of a VMware Virtual Machine Disk format (VMDK) disk hung
  indefinitely, the backup of the corresponding VM would wait
  until a timeout was reached by the backup job (typically two
  hours after the hang started). This would cause a VADP stream to
  be held by the stuck VM backup, starving other jobs of VADP
  streams and causing failure messages of the form, "There are no
  active storage streams all active vms are in initial stage or
  waiting for available streams." Since 10.1.15, a more localized
  timeout has been added to the VADP service, causing the disk
  open call to unblock within 10 minutes if the call hangs,
  freeing up the VADP stream much sooner and unblocking the backup
  of other VMs.
