Hi,

the patch seem to generate now similar guid than nexenta

But It doesn't help for the gui error

My understanding is that nexenta generate a cache somewhere, and something it's not filled

some log:

Nov 06 17:03:09 (1:1.5) EXCEPTION: ObjectNotFound: ScsiDiskContainer::list_lun_mapping_entries(MainPool/vm-296-disk-7): Unable to locate the specified zvol 'MainPool/vm-296-disk-7' 

2013-11-06 17:10:08,255 nza ERROR com.nexenta.nms::/Root/Stmf/ScsiDisk::list_lun_mapping_entries(dbus.String(u'MainPool/vm-296-disk-9')): com.nexenta.nms.ObjectNotFound: Unable to locate the specified zvol 'MainPool/vm-296-disk-9' 



after waiting some minutes, or rlauching the nms service (webgui service) (#svcadm restart nms)

It's working again

(The module is in python, but closed sources, compiled .pyc, I can't see what it is doing)


restarting nms stop the web gui for some minutes,

but in the logs it's showing:
Nov 06 17:28:15 Starting...
Nov 06 17:28:15 Syncing devices...
Nov 06 17:28:22 Syncing LUNs...

So I think it's rebuild the luns cache or something similar


I'll try to find an easy way to reload this cache. (through ssh command)

If the solution works it will cause no problems to only use 11 digits 
when naming a lun since max luns per target is limited to 2^14 or 16384 
and using 11 hex digits is an astronomic large number 11^16
