Error description

  • Restore of replicated data from the target server fails with
ANS1028S An internal program error occurred. In the error log
prior to this message an ANS0361I DIAG: fileio.cpp (3173):
fioWrite(): Unrecoverable error: NNNNNN Bytes left in receive
buffer with a BLOCK_EOF sdb type can be found. Or in other cases
the restore of replicated data from the target server fails with
ANS4020E The data format for object '<failing path and file
name>' is unknown. The unknown format usually occurs when the
file was backed up or archived by a later version of IBM Tivoli
Storage Manager.
Restore of the original source objects from the replicating
server complete without error
For the ANS1028S/ANS0361I situation a service trace of the
failing restore is needed to determine the problem object and
it's object id. Searching the trace for the "BLOCK_EOF" entry
will identify the failing object name. Searching the trace for
the versid that follows will provide the object id. A show invo
using this object id on the target server will show that the
bitfile size of the object in bitfile object entry the is larger
than expected (larger than the size in the inventory object
entry):

The replica id in the show invo output for the problem object on
the target can be used on the source to get the show invo output
for the original object and the bitfile size will be a smaller
correct size.
The problem with the replicated object is being created at
replication time. A trace of the replication on the source
server shows that there is a preemption of the replication of
the object occurring. In the reporting case the object was
originally being replicated from an active data pool. During the
replication processing from this pool a preemption occurred, rc
3008 (GRC_SEGMENT_PREEMPTED). The replication continues
processing the object using another pool as the source but
begins from the start of the object. This results in the
replicated object on the target being larger (having more data)
than it should. And subsequent restores fail.
A BFRTRV trace of the replication introducing the problem will
show the rc 3008 for one device class and then the attempt to
retrieve the bitfile from a different device class:
02:08:24.767 [381473][bfrtrv.c][4474][RtrvOne]:afRtrv returned
3008 for FILE ADP.
02:08:24.768 [381473][bfrtrv.c][4505][RtrvOne]:Attempting
retrieval of bitfile 98765432 from DISK.
With this level of preemption there is no external messaging
that it has occurred.
Tivoli Storage Manager Versions Affected: 6.3.5 and 7.1.x.x on
all platforms

Local fix

  • To avoid the problem use the NOPREEMPT server option or
determine source of the preemption and configure the server to
keep that from occurring.
To correct any problem objects once replicated with this issue:
- Backup the problem object(s) on the source and re-replicate
them to the target.
Or
- Delete the problem objects from the target replication sever
and re-replicate the node.
