IC81824: DATAPOWER NFS WRITE OPERATIONS MIGHT NOT REPORT FAILURE WHEN PERFORMED AGAINST AN UNRELIABLE REMOTE NFS SERVER

APAR status

• Closed as fixed if next.

Error description

• DataPower write operations over the NFS protocol might not
  report internal write failures when performed against an
  unreliable remote NFS server.
  
  DataPower write operations can be compromised if the NFS server
  crashes, goes down, experiences slow performance or reboots
  while these write operations are in progress.
  
  Under these conditions, the RPC re-transmission sequence will
  end after a timeout, because the NFS Volumes in DataPower are
  soft-mounted.
  

Local fix

• Insure that your NFS server and the network connectivity to the
  NFS server are stable.   For situations, where several DataPower
  appliances are using the same unreliable NFS server, you may
  wish to investigate a High Availability NFS server solution.
  
  Until this is fixed, write operations on NFS Volumes (read-only
  volumes are not affected) should be avoided if the NFS Server is
  unreliable. The following alternatives can be chosen for the
  different uses of NFS in the appliance:
  
  - Logging targets: choose a different log target type for
  logging messages; for example, you may log the messages to the
  files in the hard-disk of the appliance and select a best fit
  archiving option, either rotation or upload using FTP (all
  appliance types)
  
  - B2B Gateway Archive Target: It is recommended to use FTP or
  SFTP  to upload the archive files to a remote data store. You
  can also select any other supported protocols; such as,  FTP,
  FTP over SSL, SFTP, HTTP, HTTPS, MQ, MQFTE or RAID.
  
  - NFS Destinations: for destinations used in any of the
  gateways, via Routing URL or stylesheet extensions, such as
  url-open(), you can select any other supported protocol
  available.
  

Problem summary

• This will be fixed in the next major release.
