connect multiple disc from one target to single host.

[Marc Aymerich]

Hello,
I'm new in iscsi environments and I find that I am unable to connect
more than one disc iscsi from SAN MD3000i to a single host. I use the
initiator open-iscsi under debian. I hope you can oriented a little
bit in how to do it.

thank you in advance.
Marc

Did you set your MD3000i to authenticate against your IQN or IP?

Is the disc you are seeing called 'Xplector something.." ?

Hi konrad, thanks for your response!

For connect disks I use this comand:

iscsiadm -m node -targetname iqn.2005-02.au.com.empresa:san.200G.samba
-p 192.168.1.110 -l

indeed I am seeing two disks, but only one of them is 'valid'. The
other I think is the "Xplector something .." This is the output of
lshw.

I am unaware of the iscsi, allow me a silly question, an initiator can
connect with more than one disc? I ask because the target MD3000i
doesn't let me put the same initiator in more than one disk. Is this
normal?

Yes.

I think you are confusing how the MD3000i shows the data. You want to
assign LUNs to your "disk". Look in the manual on how to do this.

yes, I am really confused because I am surprised not being able to add
a host to several groups. Do we really can only be a host to a group?

I would suggest you call Dell's technical support to walk you stey-by-step
through what you want accomplished.
