how to move a specific dynamic ip in OneFSv8.0

Phil,

Thanks, I can move the dynamic ip successfully.

But does OneFS 8 support a more "correct" way of doing this? The classic command does not really sound like the right way to go about doing this? One would expect the feature to be removed in a later release?

We have allot of FTP connections in our environment, and when upgrading or failing a node, we need to control the ip allocation manually. If we just move the IP-adresse, all active FTP connections to the pool will fail, as the connections are stateful. We start by suspending the node and drain the active connections. After the drain (1-2 hours), we want to move the allocated IP-adresses to other interfaces, and then back when the service task has been completed.

The command isi_sc_put_ip was re-added in 8.0.1.x

isi_sc_put_ip (isi_sc_put_up appears to be a typo in previous post) was re-added in 8.1, not sure about 8.0.1.x but definitely not present in 8.0.0.4.

Usage: isi_sc_put_ip --sc-ip --sc-iface

Options:

  --sc-ip=SC_IP        IP address to move/put (must be in a dynamic IP Pool)

  --sc-iface=SC_IFACE  Destination node:interface for IP (must be a member of

                       the same dynamic IP Pool as the IP being moved)

  -h, --help           show this help message and exit

i also don't see anything in OneFS 8.x CLI guide ?

thanks Yan, i will have to use isi_classic as i am on 8.0.0.4

Isilon developers consistency is horrible, every minor release and half  #@!#$ is broken.

The command isn't in the guide because it isn't meant for production use. The command was included in the "support" namespace because it is there specifically for testing/support purposes. It was removed because it was not a supported command. The later addition of the command as isi_sc_put_ip was done so that support still had access to it after it was removed from the customer-facing namespace. Running this command for production use is not supported.

To statically assign an IP should NOT be a support command.  Anybody should be able to do it.

isi_sc_put_ip does NOT statically assign IPs. It just forcibly moves an IP in a dynamic pool and bypasses smartconnect. Once assigned, it will not necessarily remain on that node, it is still bound by the same rules as any other in a dynamic pool. If you want static IPs you can use static pools.

I understand this. I would assign IPs then set pool to static. I just don’t have a method to move an IP anymore.

Ahh, now that is a completely different discussion. When a pool is changed from dynamic to static, the IPs are all torn down and reassigned in list order, first IP in list to first node in list (nodes are arranged in list by lowest ID up). As new nodes are added to pool, they are appended to the bottom of the list and given the next available static IP. The method you describe would fail because you'd lose anything you try to force assign in the dynamic pool. The simple answer is that in order to specify an IP in a static pool, you need to remove the node that owns that specific IP and then add the node that you want to have that IP next - which is of course a really flawed method.
