Let us make some testing to check the upgrade path for 5.5. I'll write here in a day. Thanks, Last night i went ahead and reattached the remaining out of sync targets and everything is fully in sync now. tonight i was planning on upgrading to do the following: shutdown all VMs detach all storage in...

I am wondering about what my upgrade path should be for an older 5.5 install. We have started having blue screening issues on a San pair when one is rebooted gracefully the other blue screens and reboots. it has done this twice so far and we are up to date on support and licensing so i was going to ...

Got it, Did you connect all the targets through the Xen console before connecting the SRs through the GUI? They should appear available after you connect all the 4 targets (if that's 2 HA devices) yes. if i run the following commands on both xenservers iscsiadm -m discovery -t sendtargets -p 10.0.0...

Wait a moment, did you try to add the target by adding both IP's to the discovery IP tab (IP1;IP2 AFAIR) then the only available target and LUN will be the one marked with *. This should result in propper connection. i no longer get a failed to detect storage error but it is not detecting the prope...

When using HA you must know that all the LUNs are 0.

OK. I am just throwing ideas out. As i need to get this rolled out but things are still not adding properly. any ideas on how to fix it.
Thanks,

Yes, that's correct. Every change to the conf file requires service open-iscsi restart command to apply the changes. I have ran the service open-iscsi restart on both then also tried rebooting both xenservers and tried again. i am still having the same results when trying to add the storage with bo...

Here are the results after editing the multipath.conf on both xenservers and also running service open-iscsi restart on both.

Getting further but not there all the way (notes are int he screen shot also)

you need to add polling_interval 10 path_grouping_policy multibus right after the "user_friendly_names no" line in the config Max, I have updated the multipath.conf as specified. i am guessing i will at least need to restart openiscsid for it to apply correct? either way i will give it a ...

Can you tell us which multipathing option you've selected in the multipath.conf (path_grouping_policy) Group_by_prio/multibus/left defaults? sorry for the delay i have been out of town. here is the multipatch.conf defaults section defaults { user_friendly_names no } under this there is a bunch of d...

and here is an updated visio with all addressing and bonding.
Thanks,

And here is the commands used on xenserver console prior to adding iscsi in xencenter and the end result in xencenter.
here are the device details for when the target and device was created.

Since the last post this is how things are configured right now.
Also this is a full screen shot of a LUN created and presented to XEN. next post will have more screen shots...

I just ran through the process i use to connect HA storage using multipathing on previous installs which is. create ha target run following commands on each CPU node iscsiadm -m discovery -t sendtargets -p 10.0.0.115 iscsiadm -m node -T iqn.2008-08.com.starwindsoftware:10.0.0.115-entaa-dc -p 10.0.0....

here is the other screen shot.
