iSCSI on Solaris

Following our iSCSI implementation tests on Netapp/Linux, me and my co-worker decided to take a swing at trying this on our Solaris “play” boxes. Since some of our test Blades were running different beta/GA versions of Solaris 10, we started out on one of them. First we downloaded the Cisco iSCSI 3.3.6 driver for Solaris from the Cisco site. After installing it and configuring it on our Sun Blade 100 running Solaris 10 (3/05) just like how we did in our Linux implementation, we fired it up and immediately noticed the following error messages:

Bummer. Couldn’t claim target ? hmm..

:( - Must be a Solaris 10 thing,

While I was reading the RFC and looking at the linux source code for possible clues, Eddy went out and installed the same driver on a Solaris 9 box. Again, same exact steps as above with different results.

Hello! So the next thing to do is to issue a devfsadm command to Solaris to build the device pathnames so we can start accessing the disk.

# devfsadm -Cv

# format
Searching for disks…done

So far so good.
