RE: Black listing CLARiiON "LUNZ"?

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.

Subject: Black listing CLARiiON "LUNZ"?

 

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?
