Backup Central

Hi List,

for a few weeks one of our Exchange server full backup is failing.
We performed cli and gui FULL backups but each time the FULL backup
ends with the following error message:

dsierror.log :
ANS1017E Session rejected: TCP/IP connection failure
sessSendVerb: Error sending Verb, rc: -50
ANS1017E Session rejected: TCP/IP connection failure
sessSendVerb: Error sending Verb, rc: -50
ANS1017E Session rejected: TCP/IP connection failure
tdpexc.log:
Backup of storage group Storage Group 1 failed.
ANS1017E (RC-50) Session rejected: TCP/IP connection failure
Retrying failed backups...
Backup of storage group Storage Group 1 failed.
ANS1017E (RC-50) Session rejected: TCP/IP connection failure
Retrying failed backups...


Up to the failure >100GB were transferred to the TSM server.

We did not yet see any issues on the network card of the exchange
server though.
TSM is run on AIX. I just ftped a 100GB to the AIX server successfully.

Which trace option will show if Exchange does not send data before
session times out ?

Thanks,
--Eg

Note that you only examined one side of the logging: review the TSM server Activity Log. There, you may well find a timeout for the session, which you can pursue. If the server is using default values, the timeout values are probably too low.

What does you TSM server activity log show ?
Any additional messages ?

Hi,
the server actlog shows after sending of 114GB backup data.
ANE4993E (Session: 129167, Node: EXCH_TDP) TDP
MSExchg ACN3502 Data Protection for Exchange: full backup of Storage
Group 1 from server EXCH_TDP failed, rc = 418. (SESSION: 129167)

As the TDP does not send more data the TSM server the session is
terminated after the connection timeout value (7000s).

There are 4 storage groups on that Exchange server but only two of them
(1+2) keep failing - for FULL backups.

ADSM-L search results point to a network issue for RC=418. Why finishes
the backup successfully for the other two storage groups?

I played around with TDPBUffers and TDPBufsize settings and somehow one
full backup of SG1 finished successfully. I cannot recreate that though.


Is that a TDP or Exchange 2007 issue ? How can I track down if Exchange
does not send any data to TDP or the TDP cannot send any further data
to TSM ?
Which Exchange Logs show more details. The application eventlog does
not help.


Thanks.

Hello Eg,

I recommend opening a PMR with IBM support.
They will be able to examine the trace and determine
what is happening.

Thanks,
