Re: SLES10 SP3 x86_64 - connection2:0: detected conn error (1011)
I have got a reproducible test case for this. It seems that SCSI layer returns DID_BUS_BUSY many times when 'conn error (1011)' is seen. for p in `ls /dev/sd*` do dd if=$p of=/dev/zero count=1 done wait # ./io-script 1+0 records in 1+0 records out 512 bytes (5.1 MB) copied, 0.177076 seconds, 28.9 MB/s dd: reading `/dev/sdaa8': Input/output error 2976+0 records in 2976+0 records out Dec 14 11:15:12 cdc-r710s3 iscsid: Kernel reported iSCSI connection 1:0 error (1011) state (3) Dec 14 11:15:13 cdc-r710s3 kernel: connection2:0: detected conn error (1011) Dec 14 11:15:13 cdc-r710s3 iscsid: connection2:0 is operational after recovery (1 attempts) Dec 14 11:15:13 cdc-r710s3 iscsid: Kernel reported iSCSI connection 2:0 error (1011) state (3) Dec 14 11:15:14 cdc-r710s3 kernel: connection1:0: detected conn error (1011) ...

Simply starting the session does not cause these errors. On starting the second session, I start a daemon that does SCSI commands like INQUIRY on all the paths.
