Isilon

[purnesh natarajan]

Hi All,

Someone please say how can we determine which client machines are using an IP to map their smb share not by unc path. They are wanting a seamless upgrade to happen without interruption so rolling upgrade is carried out. 

Just want to get list of machines that use IP's instead of unc path. 

Let me know what command is used on 8.1.2

Thanks,

Purnesh N

SO you.re saying that instead of connection to say \\isilon.company.com\sharename they are connecting to one of the IP's directly say \\192.168.1.10\sharename?

If so there isnt any way as the connection will just be going to that node.

The way isilons work is they are a dns zone and when you query isilon.company.com your dns servers should say that its a delagated zone and pass the dns request onto the smartconnect vip address on the isilon, the isilon then returns the dns query with whichever node is least busy/has fewest connections based on your smart connect zone policy.

There is no way to spot people connecting direct to an isilon node

Incidentally unless you are following best practise, then you have a pool of addresses that float between nodes and the node going down will force those ips to be distributed between the remaining nodes.

If you do an isi network subnets list you should see something like:

ID                Subnet           Gateway|Priority   Pools       SC Service Addrs
-------------------------------------------------------------------------------------------------
groupnet0.subnet0 192.168.240.0/22 192.168.243.254|10 pool0       192.168.240.100-192.168.240.100
                                                      stg00040-1
                                                    .  ............

If the ips in use are in the pool address they should be redistributed.

we have individual ips for each node that are static for monitoring purposes, so that we can determine which node goes down but those arent actively connected to by clients.

I can't quite remember if there's a command to identify them, but you should be able to see from the network traffic. As they are using an IP address to connect, they will be unable to use Kerberos authentication. As they aren't using Kerberos, their identities are not cached and they will have to re-authenticate constantly to access their shares.

Sorry that should have been isi network pools list

Here you can see the main pool with 50 or so ip's and then manual entries for each node

This sounds like you should run a powershell script against all your clients or bash/Python  for linux lots of examples out there to get this info via powershell.  The most basic windows command being “net use “ to show you how it’s mounted 

This is the safer bet since you don’t know if the clients are active or not.. 

Also I would think mounts are controlled via group policies or something else automated. Do you let user just mount manually?

Can you describe your dns infrastructure?  The isilon might give you false info even if you mount the isilon via ip from your client as it will do a reverse dns look up.  When displaying via various commands

I found a solution that if we drain the nodes that will leave the clients which are connected to node on IP. If they are connected through full network share path they would be automatically redirected to next node netowork pool. 

Thanks for all your inputs 

Paul, Alistair and Saker.
