With REDFERN1 set up with networking, memory, and extra local disk space, it is now time to configure DNS and iSCSI disks.
Used the procedure at DNS to implement the new IP addresses documented at IP Addresses.
Create New LUN Group
On NARRABRI, I created a new LUN group called REDFERN for target, iqn.1994-11.com.netgear:narrabri:4eca4c51:redfern.
Create New LUNs
Using the design at Planning, the following LUNs were created NARRABRI:
All of these LUNs are assigned to the REDFERN LUN group.
Configuring an iSCSI Initiator
Followed the procedure in 17.6.2 Configuring an iSCSI Initiator.
Install Package
Ran the following command as root:
yum install iscsi-initiator-utils
The output is:

Discover Targets on Narrabri
When I tried the command described in the manual, I got the following result:
[root@redfern2 ~]# iscsiadm -m discovery --type sendtargets --portal 192.168.1.253 iscsiadm: Please specify portal as <ipaddr>[:<ipport>]
Instead of using the command described, I used the example from the info page to interrogate NARRABRI (192.168.1.253):
iscsiadm --mode discoverydb --type sendtargets --portal 192.168.1.253 --discover
The result is:
Starting iscsid: [ OK ] 192.168.1.253:3260,1 iqn.1994-11.com.netgear:narrabri:69444463:ovmvictoria 192.168.1.253:3260,1 iqn.1994-11.com.netgear:narrabri:4eca4c51:redfern
Establish a Session
iscsiadm --mode node --targetname iqn.1994-11.com.netgear:narrabri:4eca4c51:redfern --portal 192.168.1.253:3260 --login
This failed with the following error messages:
Logging in to [iface: default, target: iqn.1994-11.com.netgear:narrabri:4eca4c51:redfern, portal: 192.168.1.253,3260] (multiple) iscsiadm: Could not login to [iface: default, target: iqn.1994-11.com.netgear:narrabri:4eca4c51:redfern, portal: 192.168.1.253,3260]. iscsiadm: initiator reported error (24 - iSCSI login failed due to authorization failure) iscsiadm: Could not log into all portals
I changed the properties for the REDFERN group to Allowed Initiators: Any. The result is now:
Logging in to [iface: default, target: iqn.1994-11.com.netgear:narrabri:4eca4c51:redfern, portal: 192.168.1.253,3260] (multiple) Login to [iface: default, target: iqn.1994-11.com.netgear:narrabri:4eca4c51:redfern, portal: 192.168.1.253,3260] successful.
However, I am getting the following errors:
WARNING: at block/genhd.c:1474 __disk_unblock_events+0x10e/0x120()
This looks like I have a problem with OEL6u3 and iSCSI on NetGear ReadyNAS.
