Error description

• A NAS NDMP restore can fail with the following errors reported
  in the activity log:
  
  ANR9999D_2255209874 AsReadSegRemote(asrtrv.c:1515)
  Thread<748477>: Unknown error 4303 from
  
  spiRtrvSeg, pluginType 1. (SESSION: ######, PROCESS: ####)
  
  
  ANR1078E NAS Restore process ### terminated - internal server
  error detected. (SESSION: ######,
  
  PROCESS: ###)
  
  
  The DSMFFDC.log shows the following:
  
  [ FFDC_MSG_FROM_NDMP_DEVICE ]: (ndmpspi.c:3456) Mover seems to
  have stalled - aborting retrieve
  [ FFDC_MSG_FROM_NDMP_DEVICE ]: (ndlog.c:137) RESTORE: Error: job
  aborted
  [ FFDC_MSG_FROM_NDMP_DEVICE ]: (ndlog.c:137) RESTORE: Error:
  writing to symbol table interrupted
  
  due to an abort.
  
  This is the same failure described in APAR IT36030, yet an
  upgrade to V8.1.12.100 does not fix the
  
  issue. The restore stalls and then is aborted after a certain
  stall timeout value.
  
  IBM Spectrum Protect Versions Affected:
  Spectrum Protect server on all supported versions performing
  file level NDMP restore.
  
  MDVPARTL 8.1.12.100-TIV_5698MSV | IT36030
  

Local fix

• There is no local fix available at the moment.
  
  A new server option will be introduced in future releases to
  allow admins to manage the stall
  
  timeout value.
  
  Option name:
  NDMPStallTimeout
  
  Description:
  The value specifies how many minutes to wait for an NDMP filer
  to send data to the IBM Spectrum
  
  Protect server during a backup. The default is 30 minutes.
  
  
  Please reach out to IBM Spectrum Protect support for more
  information.
