unsupported SCSI

[guenterg]

Hello,

I'm new to FreeNAS and have the following Problem.

When i want to connect an iSCSI target from a OpenSUSE 11.4 I'll get the following errors:

Code:

Aug 21 13:01:37 freenas istgt[2042]: istgt_lu_disk.c:6737:istgt_lu_disk_execute: ***ERROR*** unsupported SCSI OP=0x4d
Aug 21 13:01:37 freenas istgt[2042]: istgt_lu_disk.c:6737:istgt_lu_disk_execute: ***ERROR*** unsupported SCSI OP=0x37

I use FreeNAS 8.3.0-BETA1, OpenSUSE 11.4 with iscsitarget 1.4.19-9.3, open-iscsi 2.0.870-37.38.1, yast2-iscsi-client 2.20.0-3.1 and yast2-iscsi-server 2.19.0-4.2 installed.

To connect I use the following command on OpenSUSE:

Code:

iscsiadm --mode node --targetname  iqn.2012-08.***.XX.XX:freenas:****** --portal ###.##.#.## --login

Any idea what could be wrong? Anyone has a working configuration with openSUSE 11.4?

Günter

Hi,

I have now upgraded the OpenSUSE to 12.1. After the upgrade I get this errors very frequent, about every 20 seconds. I can access the iSCSI Share without a problem.

Any idea about the error?

The errors you are seeing are generated because the initiator is generating SCSI requests that the target doesn't know what to do with.

37 INITIALIZE ELEMENT STATUS WITH RANGE
4D LOG SENSE

Those are the SCSI commands that the errors correspond to.

Are you running any hardware monitoring tools on the linux box that could be trying to punch things down to the target, for instance smartd?

Thank you very much for your quick reply!

Yes, that's it. I'm running nagios and check_mk on that linux box. After stopping nagios I haven't seen the error messages any more. So I will exclude the device from the checks.
