ANR2971E Database backup/restore/rollforward terminated -DB2 sqlcode -2071 error

OS Platform: AIX 6.1

TSM server Version:6.2.2.30

ANR2971E Database backup/restore/rollforward terminated -DB2 sqlcode -2071 error. This error comes when libApiTSM64 library file could not be loaded which resides in /usr/tivoli/tsm/client/api/bin64 directory. Reinstall the latest version of ba client and problem should be resolved. In my case I installed 6.2.2.3 which is the latest client version available on ftp site and problem got resolved. It could be because of incorrect installation or corrupt library file.

When reviewing db2diag.log file for diagnostic,  message "An error occurred while accessing the shared library" can confuse with tsm library sharing in case of library manager/client setup. SQL message here refers to the library file libApiTSM64.a in client api directory.

stale NFS handle ( GPFS filesystem backup using TSM )

GPFS mmbackup uses dsm.opt at default location i.e. /usr/tivoli/tsm/client/ba/bin in case of AIX if file is inside bin64 then we need to create symbolic link for dsm.opt to point at default location.
Or this problem could be because of a filesystem earlier mounted as NFS made local.

LTO3-LTO4 compatibility

I came across a situation where I was asked whether LTO3 media written on LTO4 drive is readable in LTO3 drive.

Answer is yes because LTO does not allow writing a different format on one media type.

I have seen this in one of my customer's environment where library is using a mix of LTO3 and LTO4 drives with all LTO3 media and there has never been any issue while restoring data using LTO3 drives ,doesn't matter whether data was written in LTO4 drive. On LTO3 media , LTO4 would be writing in LTO3 format only.

All LTO generations are backward compatible with one generation back for both read/write and two generation back for read only operations.

tapeutil no more supported

Tapeutil utility has been replaced by ITDT( IBM Tape Diagnostic Tool) which is a separate utility and can be downloaded from IBM fix central or ftp site. IBM tape device driver (i.e. Atape.driver) comes with AIX filesets.
