ANR2020E BACKUP NODE: Invalid parameter - <name>

Troubleshooting


Problem

The BACKUP NODE command is used to backup an NDMP device and fails with the ANR2020E error.

Symptom

An example of the error follows :

tsm: MYTSM_SERVER1>BACKUP NODE myndmp /backup_test MGmtclass=NAS_30_DAYS TOC=Yes Wait=No Mode=full
ANR2020E BACKUP NODE: Invalid parameter - /backup_test.
ANS8001I Return code 3.

Cause

Incorrect file system specified on the BACKUP NODE command

Diagnosing The Problem

Capture a Tivoli Storage Manager server trace with the "SPI" traceflag. For example :

13:28:09.150 [58][ndmpspi.c][3610][spiTrace]: Entering ndmpGetNextFilesystem, handle: 0000000010520960.
13:28:09.840 [58][ndmpspi.c][3637][spiTrace]: returning file system /ndmpclus/backup_test, spiRc=0.
13:28:09.840 [58][ndmpspi.c][3610][spiTrace]: Entering ndmpGetNextFilesystem, handle: 0000000010520960.

In the above example, it shows that the file system name returned by the NDMP device is /ndmpclus/backup_test.

Resolving The Problem

In this case, the backup node command used was :

BACKUP NODE myndmp /backup_test ...

The command specifies to backup filesystem "/backup_test". This is an incorrect filesystem name. The NDMP device reports the filesystem name as "/ndmpclus/backup_test". Rerun the command with the correct filesystem name. For example :

BACKUP NODE myndmp /ndmpclus/backup_test ...
