no iscsi disk on iscsi-client

Maaz — Wed, 27 Jan 2010 14:24:07 GMT

iscsi-client OS: SLES10 SP3 i586

I configured this SLES10 SP3 box an iscsi-client via YaST (yast2 iscsi-client), but 'lsscsi' or 'fdisk -l' doesnt show any iscsi-disk

and then

What kernel and iSCSI client revisions are you using?
