Vplex, RedHat and Powerpath.

Hello Everbody;

I wanna know something about the relationship with vplex and linux redhat.

I am using vplex and give some luns to a redhat host, everthing goes fine we can see the luns from powermt.

But if when we created logical volumes from the paths that we can see on powerpath, we started to get some /var/log/messages like 

 

end_request: I/O error, dev sdv, sector 0

Sep 11 14:39:01 sappro02 kernel: sd 3:0:3:0: Device not ready: <6>: Current: sense key: Not Ready

Sep 11 14:39:01 sappro02 kernel: Add. Sense: Logical unit not ready, manual intervention required

We look at the discussion form of RedHat and we get some results, they said that when we look at cat /proc/scsi/scsi we see the storage model is invista in vplex environment. (We see DGC in single node storage) And linux guys told that invista models can not see the powerpath as active active, linux see the invista model storage types as active passive. In storage configuration we choose active-active failover mode but after vplex it turns to active passive in linux environment.

The errors that we get are from this problem, linux see invista vplex storages paths as active passive. the errors are from passive paths.

Do anyone know something about this situation?

How can i look at the failover mode of the initiators of vplex in vplexcli?

Thanks.
