Re: [Xen-devel] NetApp vfiler example scripts

The OnTap interface is the SSH commandline interface you're using, right?  It 
does sound cleaner to avoid that; I wasn't 100% convinced by the use of that 
in the Xen script as it seemed like an "unexpected" behaviour for a low lever 
block script...  On the other hand, presumably it makes interacting with the 
filer a bit less friendly.

I don't know what the reply you've already seen is regarding but for the patch 
in question, it seems like it would be reasonable to just submit to the 
xen-devel list and request a merge.  I wouldn't be surprised if there's 
someone within Citrix working on NetApp integration (speculation on my part, 
since I'm not strictly a Citrix/XenSource employee and generally lack inside 
information) but equally well, they'd not necessarily be concerned with the 
OSS version of Xen.

Ah, I thought I'd seen an iSCSI patch whizz by on the mailing lists at some 
point - hadn't realised it was also you!

Have you done any further work on this or is the original patch posting on the 
2007-11-25 the most recent state of the patch?  Browsing the mailing archives 
I also see a script from Kurt Garloff mentioned.  Do you know if it is yours 
that is in SuSE or Kurt's?

It certainly seems like it'd be desirable to have these scripts in upstream 
Xen where possible, especially if distros are shipping them and people want 
to use them!

Cheers,
Mark
