> Dear all,
>
> i'm running in a problemw with two TSM servers, i do not understand:
>
> both, TSM client and server are located on the same maschine and use
> sharedmemory communication.
>
> well, the performance is quite good, but i found several warnings
> "ANS1809W - A session with the TSM server has been disconnected." in the
> dsmerror log.
>
> the explanation due to the IBM infocenter directs to network problems, but
> shared memory does not use a network? or am I wrong?
> so, that's why i do not understand what's the real problem.
>
> i see those messages mostly on my windows servers, linux seems to have
> much less of them, but some.
> first i thought, there's correlation with the number of nodes accessing
> but they appear when there're only a few nodes (four or five) and the
> number does not increase if there are more nodes the same time.
> i doubled the values for COMMTIMEOUT (now 600) and IDLETIMEOUT (60), but
> it seems to have no effect.
>
> neither "top" / "nmon" nor the windows performance monitor gives me a
> hint, that the server are at their performance limits.

> => does anyone had the same problem?
> => any guess, what to do?

> used systems:
> 1) Dell R610 (12 Cores, 48 GB RAM) with SLES 11 SP3, TSM 7.1.0 server and
> client, backing up a 130 TB HSM filesystem using 28 dedicated nodes
> 2) Dell R620 ( 8 Cores, 48 GB RAM) with Windows 2008R2, TSM 7.1.0 server
> and client, backing up a 90 TB HSM filesystem using 16 dedicated nodes
>
> both servers act as a "gateway node" to the SAN-based HSM filesystem and
> therefore have direct and local access to the filesystems to be backuped.
