I have a TSM environment with a libray manager and 100 Storage agents running mainly in AIX.
The Library Manager has also a normal TSM server role with about 400 clients.
The backup environment consists of 2 IBM ProtecTIER clusters and a toltal of 4 virtual libraries.
We have a total of 384 virtual tape drives accessed by 8 HBA ports in the Library Manager and among the Storage Agents.
The Library Manager runs in AIX (7.1) and on a Full partition (LPAR with no virtual devices).
...
Periodically we experience ANR8311E and ANR0523W errors which lead to DB2 API session failures.
We can't determine the root cause and no AIX errpt errors show and also no problems with the SAN fabrics or any alerts from IBM ProtecTIER.
I'm looing at the HBA port settings for both the Libarary Manager and all Storage Agents now.
-> My question is really what is the current HBA setting recommendation for VTLtape when using IBM Power 7 (8Gb PCI Express Dual Port FC Adapter), TSM 6.4 and AIX 7.1 ?
Should we use "fc_err_recov" = delayed_fail or fast_fail and whats the recomended dyntrk setting?
Thanks for some input
