Dynamox,

Yes sir, more times than I could count. I've re-install Powerpath several times and you need a couple of reboots for that process.

Thanks

Steve,

have you tried rebooting the system? Sometimes PowerPath does not take control of the LUN correctly and you have to bounce the box. It happens very rarely but it does happen.

Have you check on the CX3-80 in Connectivity Status that you have the correct number of paths that you zoned? Highlight one of the paths and click on INFO - the Failover Mode should be set to 1 - check each of the paths to ensure that all paths have the same failover mode.

Next, check in the Storage Group for the host - right click on the Storage Group name and select LUNs (or Properties) - is the LUN that is in the Storage Group listed as Host LUN 0 (zero)? If it isn't, remove the LUN and then add it back in and make sure that you click in the Host LUN area and select zero - the first LUN in the Storage Group should always be zero.

kelleg,

All paths are displayed in Connectivity Status, as well as logged in and registered, they also have a Failover mode of 1. The Storage Group has the Host listed and the LUN has a Host ID of 0. Dell has suggested that there may be a conflict with W2k8's native MPIO drivers and PowerPath. So I removed that feature with no success.

Thanks

I had a similar problem with 2008 in a cluster environment, it was boot from san but also had ghost disks, the solution was to run the following command on the host and reboot

emcphostid set -no_prompt
