IT37476: VADP PROXY NOT RELEASED IMMEDIATELY AFTER THE RESTORE FOR A VIRTUAL MACHINE IS COMPLETED

APAR status

• Closed as program error.

Error description

• During an IBM Spectrum Protect Plus restore job, the VADP proxy
  is not released immediately after the restore for a virtual
  machine is completed. This can become a problem when a restore
  job contains multiple virtual machines and some need to wait for
  a VADP proxy to become available after the softcap task limit is
  reached, which can cause the restore job hang indefinitely with
  the following messages seen in the restore job log:
  
  WARN,timestamp,2,CTGGA0682,VM VMNAME1 is waiting for proxy. All
  proxies for site A are being fully utilized. Data streams in
  use: 4  site limit set: 4. Retrying in 30 seconds.
  WARN,timestamp,2,CTGGA0682,VM VMNAME2 is waiting for proxy. All
  proxies for site A are being fully utilized. Data streams in
  use: 4  site limit set: 4. Retrying in 30 seconds.
  WARN,timestamp,2,CTGGA0682,VM VMNAME3 is waiting for proxy. All
  proxies for site A are being fully utilized. Data streams in
  use: 4  site limit set: 4. Retrying in 30 seconds.

  Initial impact: Medium
  
  Versions Affected: 10.1.5 and later

  Restore, VADP proxy
  

Local fix

• Use either of the following options:
  1. Set a higher value for the "Softcap task limit" option if
  possible. This will assign more CPU cores to VADP proxy to
  handle the restore.
  2. Create one restore job for each virtual machine if multiple
  ones are needed to restore.
