look at the output of 'lsattr -El rmt3' on both servers and compare
output. This may reveal the reason.

Subject:        Problems configuring Library Sharing

Hello all,

We have problems configuring TSM Tape Library Sharing. Our environment is
the following:

Library manager - TSM Server v 4.2.2.0, AIX v 4.3.3

Library Client - TSM Server v 4.2.2.0, AIX v 4.3.3

Library - IBM LTO 3584, connected to SAN with Compaq Fibre Channel SAN
Switch 8-EL.

TSM Server - Library Manager is working fine with the library. When we try
to issue command "backup db devclass=lto_class" on library client, the
following error messages are written to the actlog:



On library manager:

ANR0408I Session 973 started for server GED_ADSM (AIX-RS/6000) (Tcp/Ip)
for library sharing.

ANR8337I LTO volume A00066 mounted in drive LTO4 (/dev/rmt3).

On library client:

ANR4578E Database backup/restore terminated - required volume was not
mounted.

ANR0985I Process 162 for DATABASE BACKUP running in the BACKGROUND

Could somebody tell me what these errors mean and what the problem could
be?



Best regards,
