zfs discuss - Aug 2010 - zfs/iSCSI: 0000 = SNS Error Type: Current Error (0x70)

Hi,

I''m trying to track down an error with a 64bit x86 OpenSolaris 2009.06
ZFS shared via iSCSI and an Ubuntu 10.04 client.  The client can successfully
log in, but no device node appears.  I captured a session with wireshark.  When
the client attempts a "SCSI: Inquiry LUN: 0x00", OpenSolaris sends a
"SCSI Response (Check Condition) LUN:0x00" that contains the
following:

.111 0000 = SNS Error Type: Current Error (0x70)
Filemark: 0, EOM: 0, ILI: 0
.... 0100 = Sense Key: Hardware Error (0x04)

The ZFS being exported is a 400GB chunk of a 1TB ZFS mirror.  The underlying OS
reports no hardware errors, and "zpool status" looks OK.  Why would
OpenSolaris give this error?  Is there anything I can do for it?  Any
suggestions would be appreciated.

(I discussed this with the open-iscsi people at
http://groups.google.com/group/open-iscsi/browse_thread/thread/06b83227ffc6a31a/2e58a163e21ec74e#2e58a163e21ec74e.)

Thanks,
==ml
