Windows 2008R2 and Powerpath
I can see the presented lun on server and Powerpath seems fine. However Disk Management in Windows also shows the paths to the VNX as Unknown and Offline. Like I said the lun I presented is there and can be formatted but I would think those Offline Disks shouldn't be there.
Anyone experience something similiar?
Thanks,

I just found that on a web search. I just represented LUN with host ID 0 and rebooted. Should know soon.
I appreciate the help.

It may be a matter of giving the GUI a minute to refresh. Otherwise, post the output of 'powermt display dev=all' again so we can see what has the error.
You can also post a screenshot.

Thank You!
I did the powermt check and had to delete all the dead paths associated with the old host ID. Now everything looks good.

That did it in terms of the phantom disks. Now my Power Path administrator show a red / through everything. Any idea of how to make Powerpath happy again?

Hi,
In most cases a powermt check / powermt save will resolve this issue.
Kind Regards,
