Re: [Xen-users] Xen and iSCSI - options and questions

[jpranevich@xxxxxxxxxxx]

Hello,

Ah, that is perhaps the problem then. I'm using "iscsi:" instead of "phy:" and 
replacing the colon in the IQN with a '@' per instructions that I found in the 
SuSE "xmexample.disks" file. 

For example:

disk = [ 
"iscsi:iqn.2001-05.com.equallogic@0-8a0906-4bbfbc101-51f41f3a27647d08-jpranevich,xvda,w"
 ]

That returns an error: 

[root@vs6 SOURCES]# xm create jpranevich
Using config file "/etc/xen/jpranevich".
Error: Disk isn't accessible

That error caused me to assume that the script didn't work with 3.2. Is there 
any other tweak that I need to make? Any specific way that iscsiadm should be 
run first? I notice that just the line doesn't include a portal address-- just 
a IQN. My guess was that it just looked in /var/lib/iscsi/nodes/ for the right 
addresses and configuration, but perhaps not.

Any further advice that you can provide is appreciated.

Joe

Nonsence, it is running from 3.1 to 3.2 for the last 9 months. Maybe you
don't use the right disk syntax, but that isn't really something I
responsible for.

The updated script was even included in the new SuSe distro...
