zfs discuss - Mar 2010 - Can we get some documentation on iSCSI sharing after comstar took over?

Things used to be simple. 

"zfs create -V xxg -o shareiscsi=on pool/iSCSI/mynewvolume"

It worked.

Now we''ve got a new, feature-rich baby in town, called comstar, and so
far all attempts at groking the excuse of a manpage has simply left me with a
nasty headache.

_WHERE_ is the replacement one-line command that let me create a new
iscsi-shared volume (I could then mount on my VMWare ESXi box)?

Hi Svein,

Here''s a couple of pointers:

Thanks,

This is what I used:
http://wikis.sun.com/display/OpenSolarisInfo200906/How+to+Configure+iSCSI+Target+Ports

I distilled that to:

disable the old, enable the new (comstar)

* sudo svcadm disable iscsitgt
* sudo svcadm enable stmf

Then four steps (using my zfs/zpool info - substitute for yours):

* sudo zfs create -s -V 5t data01/san/gallardo/g (the -s makes it thin, -V
specifies a block volume)
* sbdadm create-lu /dev/zvol/rdsk/data01/san/gallardo/g
* sudo itadm create-target
* sudo stmfadm add-view 600144F0E247850000004A80910A0001

This should allow any initiator to connect to your volume, no security.

Not quite a one liner. After you create the target once (step 3), you do not
have to do that again for the next volume. So three lines.

I found this useful too:
http://www.cuddletech.com/blog/pivot/entry.php?id=968

Basically a google search for "comstar iscsi" returns lots of useful
info.

So ... no way around messing with guid numbers?

That''s what I was afraid of.

Well, comstar may have a lot of features, but the one major feature the
legacy target had (it was simple to use for non-paid-by-the-hour san
admins) is gone.

Thanks a lot. ;)

I think there are ... several people that''d like a script that gave us
back some of the ease of the old shareiscsi one-off, instead of having
to spend time on copy-and-pasting GUIDs they have ... no real use for. ;)

Thank you! :)

Mind if I (after some sleep) look at extending your script a little? Of
course with feedback of the changes I make?

Certainly! I just whipped that up since I was testing out a pile of  
clients with different volumes and got tired of going through all the  
steps so anything to make it more complete would be useful.

How about a perl script that emulates the functionality of iscsitadm  
so share=iscsi works as expected?
