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 ...
