That is the 20 MB access Lun used for in-band management with the MD3000i 
controller. Its not a proper scsi LUN so you might want those error messages.

You could also choose not have it exposed to the host (in your case the debian 
server) by editing the Host to virtual disk mappings using either the MDSM 
management GUI or CLI.

Hi!

I try to setup a server with HD space on a DELL MD3000i.
I use a "old" debian system, updated to Debian Lenny with a recent
2.6.26 kernel and open-iscsi Version 2.0.870~rc3-0.3.

That setup find the MD3000i and I can "connect".
But it shows me two 21MB partitions in dmesg:

[86249.309382] sd 15:0:0:0: [sdf] Attached SCSI disk
[86249.314300] scsi 15:0:0:31: Direct-Access     DELL     Universal

[86249.945726] end_request: I/O error, dev sdf, sector 0 [86250.525251] 
end_request: I/O error, dev sdf, sector 0

On the MD3000i I created a 2000GB partition and set this exclusive to that 
debian server.

Any idea?

Lars Schimmer
