Hi list,
I have a node (tsm 5.2.3 on Windows 2003 server) having unusualy (for us
at least ..) big files to backup : > 100 GB.
Unfortunately, everytime I try to do a backup from those files, TSM
server (5.2.2.1 on AIX 5.2) breaks the session after a while with
ANR0488W, complaining that througputdatathreshold and/or
throughputtimethreshold have been reached, despite the fact that backup
is running properly with an average 10MB/s rate. The session is then
reestablished by client, and the whole cycle begins again.
Q sess on server looks like this :
Sess Number: 3.235.353
Comm. Method: Tcp/Ip
Sess State: RecvW
Wait Time: 0 S
Bytes Sent: 631
Bytes Recvd: 25,0 G
Sess Type: Node
Platform: WinNT
Client Name: PAC2KT15
Media Access Status: Current output volume(s): 000536,(2583
Seconds)

Date/Time First Data Sent: 27.08.2004 10:44:54

Client error log looks like this :
08/27/2004 10:44:39 sessSendVerb: Error sending Verb, rc: -50
08/27/2004 10:44:39 ANS1809W Session is lost; initializing session
reopen procedure.
08/27/2004 10:44:54 ANS1810E TSM session has been reestablished.
TSM activity log looks like this (filtered only for this node):
08/27/04 09:55:00 ANR0406I Session 3234823 started for node (WinNT)
(Tcp/Ip
pac2kt15.corp.panorg.com(2681)). (SESSION:

08/27/04 10:54:28 ANR0403I Session 3235418 ended for node PAC2KT15
(WinNT).
(SESSION: 3235418)
Due to log pinning problems, I can't afford to extend our
troughputdata/time thresholds (having respectively 30 and 60), and
anyway I don't get it why server would consider the session as inactive,
as it is running flawlessly.
Could anyone provide an explanation/solution for this behaviour ?
