unable to discover disk using openfiler and iscsi

[Amit Anand]

Hi,

I am trying to discover disks configured using openfiler and I get
following

[root@openfiler ~]# iscsiadm -m discovery -t st -p 192.168.1.5
[root@openfiler ~]#

I don't see any output. Then I ran with -d 2 and got following output:

[root@openfiler ~]# iscsiadm -m discovery -t st -p 192.168.1.5 -d 2
iscsiadm: Max file limits 1024 1024

iscsiadm: starting sendtargets discovery, address 192.168.1.5:3260,
iscsiadm: connecting to 192.168.1.5:3260
iscsiadm: connected local port 57864 to 192.168.1.5:3260
iscsiadm: connected to discovery address 192.168.1.5
iscsiadm: login response status 0000
iscsiadm: discovery process to 192.168.1.5:3260 exiting
[root@openfiler ~]#

And then, I run this

[root@openfiler ~]# iscsiadm -m node -T iqn.
2006-01.com.openfiler:rac1.crs -p 192.168.1.5 -l
iscsiadm: no records found!
[root@openfiler ~]#

I am not able to discover any disk on openfiler server itself. Same
thing happens when I try to do it from a client machine.

Following is the status of all the services

SMB / CIFS server Disabled Enable
NFSv3 server Disabled Enable
HTTP / WebDAV server Disabled Enable
FTP server Disabled Enable
iSCSI target server Enabled Disable
Rsync server Disabled Enable
UPS server Disabled Enable
LDAP server Disabled Enable
ACPI daemon Enabled Disable
iSCSI initiator Enabled Disable


Version information:

[root@openfiler ~]# iscsid -v
iscsid version 2.0-871
[root@openfiler ~]#


Can somebody please help? I have checked multiple times the volume
setup, iscsi-target setup and network ACL. There is nothing wrong with
it.

Please help.

The target just does not return any targets. This is normally a target
config issue. I am not familiar with open filer. Try iscsiadm with -d 8
and send the output.

Thanks for your reply. I was able to resolve the issue by modifying /etc/initiator.deny and commenting all the lines that were denying access to configured disk.

Thanks once again.
