#1 17. April 2012 Hallo zusammen, vielleicht weiß hier einer ja einen rat für mich... Ich habe hier eine Linux Maschine (Oracle Enterprise Linux 5 Update 7 x64). Dieser Server soll sich mit dem OpenFiler verbinden per ISCSI. Das funktioniert auch soweit.

Weiß einer von Euch wie ich mich mit einem expliziten angegeben iscsi Target verbinde und den rest komplett ignoriere! Als Beispiel: Code: iscsiadm -m node -T iqn.2006-01.com.openfiler:tsn.aa396ccf6b5e.rac2 -p 192.168.8.251 iscsiadm -m node -T iqn.2006-01.com.openfiler:tsn.aa396ccf6b5e.rac2 -p 192.168.8.251 -l iscsiadm -m node -T iqn.2006-01.com.openfiler:tsn.aa396ccf6b5e.rac2 -p 192.168.8.251 -o update -n node.startup -v automatic Ebenso habe ich das Problem das wenn ich auf VM1 das iscsi Target verbunden habe, ich mich auf VM2 verbinden kann, er aber die Festplatten nicht sehen tut. :-/ Code: [root@config381vm1 ~]# iscsiadm -m session tcp: [1] 192.168.8.251:3260,1 iqn.2006-01.com.openfiler:tsn.aa396ccf6b5e.rac2 Ein Ping funktioniert auch....

Network ACL auf der OpenFIler ebene ist leider keine Lösung, da ich hier von 30 VMs rede und halt auch 30 IPs. Die sich immer ändern können... Über jede Idee / Anregung bin ich Glücklich!
