[ADSM-L] SV: RHEL5-2.6.18.96 - Lin_tape 1.24-Sandiscovery wont work

Hi Jane,
I normally don't use or turn on SANDiscovery on Linux 86_64 and x86 because of 
that reason, it normally don't work. I sow a article on IBM website where you 
need to copy a library file to /opt/tivoli/tsm/server/bin or something like 
that but it never worked.

One thing that pops up in my head when I reading your email is MPIO to your 
library? Do you have multiple paths to your Tape Drives? And have you turned on 
MPIO (MPATH)


Best Regards

Ämne: RHEL5-2.6.18.96 - Lin_tape 1.24-Sandiscovery wont work

Hi,

I have compiled the latest Lin_tape and installed lin_taped on my Linux RHEL5 
server.. I am using a Netapp Nearstor VTL emulating IBM LTO4 drives. 
Sandiscovery will not work, and at best will crash the system every few hours 
or so unless it is turned off - / or set to PASSIVE. When I scan the system, 
the drives are dicovered and connected to the lin_tape driver:
lin_tape: detected device at host 1, channel 0, id 0, lun 1
IBM ULTRIUM-TD4 022C
lin_tape: successfully attached IBMtape0
lin_tape: detected device at host 1, channel 0, id 0, lun 2
IBM ULTRIUM-TD4 022C
lin_tape: successfully attached IBMtape1
lin_tape: detected device at host 1, channel 0, id 0, lun 3

but as soon as tapes start loading we get various errors:
lin_tape: IBMtape20----51868 tape_logsense_page() unable to do log sense
lin_tape: IBMtape20----51868 tape_logsense_page() unable to do log sense
lin_tape: IBMChgr1-----80401 changer_check_result() sensekey: 6 asc: 28 ascq: 0
lin_tape: IBMtape19----b4fb0 tape_set_all_parms() unable to change recovery 
timeouts

The crashing has become very annoying - IBM recommends a QLogic hba driver that 
is not supported by QLogic or RHEL5 (8.01.06) We have 8.02.23 - but that might 
not be related.

IBM has been studying the information for a while now.. but this is getting 
very frustrated. The lin_tape compiled without error for my kernel.

Sandiscovery will not adjust the devices as it does on AIX perfectly..

Any suggestions or help would be greatly appreciated.

Jane
