Isilon - drive mapping issues - unresolved SIDs
Hi,
I am running on OneFS 7.0.2.4, Win7 users connected to Isilon facing drive mappings lost issue intermittently and also when the win machine is locked and then unlocked. A reboot is required to get the drive mappings back. Also for the same users, unresolved SID are noticed but they will be refreshed in few seconds. Can someone point me in right direction to resolve this issue
Thanks,
Damal

Dimebag and Mark, thank you for your comments
The issue was with network and user specific, not from storage side.

A couple questions... When the drive mapping lost, what exactly do you see? No mapped drive? a red "x"? Something else? Can the share be accessed via UNC path? Are you front ending this with a DFS server?

Yes, there is no red X nothing and they dont exist in explorer at all. Shares can be accessed via UNC path and yes, there is DFS. It seems more like issue not from storage side

Is the drive mapped via group policy or a log on script?
Try this map a second drive in the exact same manner, but make right to isilon and not the DFS server. see if that helps..

Hi Damal,
My first guess is a problem with DNS-Entries. When a network drive dissolves usually the TTL for this DNS leads to a loss of connectivity. Do you use WINS? How do clients resolve your DFS-Name to the smartconnect-Zone?
Here is a (rather old) article describing a brief walktrough how to solve kerberos authentication problem:
Troubleshooting Kerberos Authentication problems – Name resolution issues - Ask the Directory Services Team - Site Home …
Check out this document: https://emc--c.na5.visual.force.com/apex/KB_HowTo?id=kA0700000004Jqi
I had to correct our AD-Settings as the Isilon struggles with large security token sizes. This often happend's when you use a lot of delegation or the member is part of too many AD groups.
Did you do a network trace on the affected client? It helps a lot to see the difference between a failed connection and a working connection.
PS: Is there any other OS than Windows 7?

In your login script map a 2nd drive... this time directly to Isilon and not the DFS server. See if that drive goes away also, of if its limited to the DFS drive disappearing.
That was the issue when we were seeing this problem.
