Issue mounting LUN on windows host
Hi Everyone,
We are facing a data loss situation and required your help.
We have Carrion CX4-240 integrated with a window 2003 host. There is a 7TB metaLUN assigned to the host. While accessing this Drive (7TB metaLUN) it is showing a pop up with given below message:
The disk in Drive G: not formatted. Do you want to format it now?
This issue occurred when the host got formatted and rebuilt with the same OS and configuration (LUN is not unmounted from the host when the host is formatted). Screenshot of the error is attached.
We have also performed LUN migration from the storage end assigned the migrated LUN but the status is still same.
Please assist on this as soon as possible.

Hi Glen,
Thank you for the response.
Could you please explain how can we import the LUN?.
We have already performed LUN based migration but it did not help and we are now planning to perform LUN snapshot.

Import is a Windows server operation - do a google "import disk windows 2003" that should return a number of answers. Again, I'm recommending that you work with Microsoft - they would be the best resource for this particular issue.
If you have another server, you could see if you can attach the LUN to that server.

That sounds like the Windows operating system lost some critical piece of information about that LUN - the ID? This is a Windows issue and not an array issue. As long as you don't format that LUN, the data should stay intact. Have you tried to import the LUN? I'd contact Microsoft to see if they can help you.
