Error description
Starting at Server 7.1, backups objects larger than MAXFRAGMENTSIZE, which by default is 10 GB, are split to avoid pinning the logs. If such a file is backed up to a storage pool hierarchy with simultaneous writes enabled (COPYSTGPOOLS=copypoolname) , and the DESTINATION does not have enough space and overflows to the NEXSTGPOOL, the backup will fail, but will not report any errors in the server activity log. There are 3 criteria for the problem to occur: - object must be larger than MAXFRAGMENTSIZE (10GB by default) - backup sent to pool hierarchy: destination -> next - the destination pool does not have enough space or MAXSIZE exceeded TDP Clients are more likely to see this as it's more common that they backup really large objects. The client error log will show: ANS0278S The transaction will be aborted. ANS1315W Unexpected retry request. The server found an error while writing the data. L2 Advanced diagnostic: A server trace with BF AF DF SS AS DS SW will show [ssswtr.c][1413][ssSWStore]:Source has ended STORE transfer. [bfswcrt.c][2762][StoreBitfile]:Translated ssSWStore returned 3266. [bfswcrt.c][2771][StoreBitfile]:Received GRC_SIZE_LIMIT_REACHED after 10485966832 bytes [bfutil.c][14213][BfSetSWOpMode]:Setting SW move type to 4 for pool DISKPOOL. [bfutil.c][14213][BfSetSWOpMode]:Setting SW move type to 4 for pool COPYPOOL. The GRC_SIZE_LIMIT_REACHED return code is an indication that the 10GB limit was reached. Versions Affected: Server 7.1 Initial Impact: medium Additional Keywords: zz71 SW TDP TSM
Local fix
There are 3 different workarounds: 1 - Send the backups to a storage pool that does not have a next pool. 2 - Increase the 10GB limit by using the server option "MAXFRAGMENTSIZE" in dsmerv.opt. For example, to set it at 200 GB: MAXFRAGMENTSIZE 200000 It can have a maximum value of 999,999 MB (or approx 1 TB). 3 - It's also possible to update the affected node(s) to have SPLITLARGEObjects=No, the default is yes: update node NODENAME SPLITLARGEObjects=NO
