[dm-devel] Black listing CLARiiON "LUNZ"?

[Paul Cote]

Hi Wayne;
 
We're currently locked in with RHEL 4 / Update 4 (2.6.9-42.ELsmp) with
multipath tools V4.7.
 
I'm trying to make a play for a later release... but certainly would be
quite helpful knowing which one has the fix!
 
Much appreciated.
 
Paul

	Hi Paul.
	 
	    It has been fixed upstream and is filtering down to the
distros. What version of distro are you seeing this issue in? We are
currently testing this fix.
	 
	Regards,
	Wayne.

	Hi

	 

	The array data struct for DGC (CLARiiON) shows that LUNZ is
blacklisted; but any tine that LUN is "visible" during a reboot; the
host will hang.

	 

	EMC did state this was an issue in their DM config guide; but I
thought black listing would circumvent the issue.

	 

	Any suggestions?

	 

	        }

	        device {

	                vendor DGC

	                product *

	                product_blacklist LUNZ

	                path_grouping_policy group_by_prio

	                path_checker emc_clariion

	                features 1 queue_if_no_path

	                hardware_handler 1 emc

	                prio_callout /sbin/mpath_prio_emc /dev/%n

	                no_path_retry 60

	                rr_min_io 1000

	        }
