Failures using the mmbackup command

Use the mmbackup command to back up the files in a GPFS file system to storage on an IBM Storage Protect server. A number of factors can cause mmbackup to fail.

The most common of these are:
  • The file system is not mounted on the node issuing the mmbackup command.
  • The file system is not mounted on the IBM Storage Protect client nodes.
  • The mmbackup command was issued to back up a file system owned by a remote cluster.
  • The IBM Storage Protect clients are not able to communicate with the IBM Storage Protect server due to authorization problems.
  • The IBM Storage Protect server is down or out of storage space.
  • When the target of the backup is tape, the IBM Storage Protect server may be unable to handle all of the backup client processes because the value of the IBM Storage Protect server's MAXNUMMP parameter is set lower than the number of client processes. This failure is indicated by message ANS1312E from IBM Storage Protect.

The errors from mmbackup normally indicate the underlying problem.
