Re: IO error ANR8311E with 3570 drive on AIX TSM411

     Norma,

     I think this has to do with the atape level. I remember some warning
     issued by IBM where you get harmless but annoying I/O error messages
     when atape is downlevel compared to the TSM level used, you'd have to
     upgrade to the latest atape level (5.3.?) to get rid of the messages.


     regards Walter Ridderhof

Hello:
We have TSM on an AIX system with a 3575 library connected to it.
The environment is the following:
Op. System: AIX 4.3.3.0
Tivoli Storage Manager 4.1.1.0
Library: 3575 L06
Library Microcode level: 2.19
1 3570 Drive
3570 Drive Microcode: 44D
Atape version: 4.0.4.2
TSM seems to work properly. We are able to backup and restore data
and the TSM database. But Activity log shows IO errors as follows:
ANR8311E An I/O error occurred while accessing drive
3570DRV (/dev/rmt0) for GETLOGSENSE operation, errno =22

Devclass is defined as follows:
DEFINE DEVCLASS 3570DC DEVTYPE=3570 FORMAT=DRIVE MOUNTLIMIT=1
MOUNTWAIT=60 MOUNTRETENTION=60 PREFIX=TSMLIBRARY=3575LIB
The library is defined as follows:
DEFINE LIBRARY 3575LIB LIBTYPE=SCSI DEVICE=/dev/smc0 SHARED=NO
And the drive is defined as follows:
DEFINE DRIVE 3575LIB 3570DRV DEVICE=/dev/rmt0 ELEMENT=16 ONLINE=Yes
The operating system recognizes the library and the drive properly with
Atape.

Can anybody help please????
Thanks and best regards: Norma
