iSCSI, LUN, and devices

gmex · 08-01-2007, 06:02 PM

I'm trying to connect RHEL 5 to a netapp fas270. I'm totally new to this...

I think I have all set up correctly as I get responses from the SAN device from commands such as:
iscsiadm -m discovery sendtargets -p 1.2.3.4.5

The services are all running fine etc.

What I can't understand is how to tie the raw scsi device (sdb?) to the LUN.

I have all sda devices mounted (3 drives hardware RAID as 1 volume).

How do I actually make the connection between the raw device and the LUN so I can mount it?

Just in case anyone needs the solution...

I was able to get the info from the SAN by running a tool provided by Netapp which spit out the device that was created /dev/sdc

Apparently, you can get this info from iscsi-ls command, but it's not avaialbe in RHEL 5.

Then I could see, partition it and create a file system etc. thus mount it.

Hello,

Which tool was this (the one from NetApp)?

It was /opt/netapp/santools/sanlun
$>cd /opt/netapp/santools/sanlun
$>./sanlun show
