[stgt] [RFC PATCH 0/2] Return NAA VPD descriptor, expected by Win initiator

[Doug Clow]

Alexander,

Here is the tcpdump you requested.  I start by connecting to the disk and then immediately attempt a quick format from Windows.  That produced a huge file so I uploaded it to Yousendit.  This is the download link:

>> Thanks Maurits…but one sec.  I made an error and discovered it right after I hit send.  I forgot the tgtd daemon was still running after I uninstalled the patched version.  After I installed the yum version, rebooted and then tried, I could format.  So it looks like this problem has been introduced by the VPD patch.

Unfortunately there isn't a huge amount of error messages generated.  If I try a quick format, it fails instantly.  If I do a full format, it fills up the bar to 100% and then errors at the very end.  In the Linux side the syslog message is:
>>> 
>>> May 13 13:13:37 iscsi2 tgtd: conn_close(103) connection closed, 0xb8dfe8 1
>>> May 13 13:13:37 iscsi2 tgtd: conn_close(109) sesson 0xb922e0 1

>>> and in Windows the error is:
>>> 
>>> A connection to the target was lost, but Initiator successfully reconnected to the target. Dump data contains the target name.

>>> So it seems like the connection is resetting at the end of the format operation.  Any ideas on where I could investigate?
