Clean up old DPIDs

[jbs@bbn.com]

FOAM caches the DPIDs that it sees, so that it can let you reserve resources on them even if the switch is down at the time of the reservation. If a DPID changes, the old one stays cached in FOAM. This happened on the ExoGENI racks; clean up the old DPIDs in FOAM.

I'll check this out for BBN now, and I can do it for RENCI, FIU, and UH, privs permitting, unless anyone else wants to.

Here's what's currently there:

[09:35:01] jbs@bbn-hn:/home/jbs
+$ foamctl admin:list-datapaths --passwd-file=/etc/foam.passwd
[
 "00:64:08:17:f4:b5:2a:00", 
 "00:01:08:17:f4:b5:2a:00"
]

You can safely remove them all, and the real ones will pop back. So:

foamctl admin:remove-datapath --dpid="00:64:08:17:f4:b5:2a:00" --passwd-file=/etc/foam.passwd
foamctl admin:remove-datapath --dpid="00:01:08:17:f4:b5:2a:00" --passwd-file=/etc/foam.passwd

And now:

[09:54:13] jbs@bbn-hn:/home/jbs
+$ foamctl admin:list-datapaths --passwd-file=/etc/foam.passwd
[
 "00:01:08:17:f4:b5:2a:00"
]

And the old one no longer appears in listresources output.

I'll do this on RENCI, FIU, and UH, now.

RENCI before:

[09:55:46] jbs@rci-hn:/home/jbs
+$ sudo foamctl admin:list-datapaths --passwd-file=/etc/foam.passwd
[
 "00:01:08:17:f4:b3:5b:00", 
 "00:00:9a:12:1b:ff:4e:4f", 
 "00:00:a6:e5:25:32:33:45", 
 "00:00:0e:8f:87:9d:9d:44", 
 "00:00:5e:cf:6f:90:70:42", 
 "00:64:08:17:f4:b3:5b:00"
]

Removed:

sudo foamctl admin:remove-datapath --dpid="00:01:08:17:f4:b3:5b:00" --passwd-file=/etc/foam.passwd
sudo foamctl admin:remove-datapath --dpid="00:00:9a:12:1b:ff:4e:4f" --passwd-file=/etc/foam.passwd
sudo foamctl admin:remove-datapath --dpid="00:00:a6:e5:25:32:33:45" --passwd-file=/etc/foam.passwd
sudo foamctl admin:remove-datapath --dpid="00:00:0e:8f:87:9d:9d:44" --passwd-file=/etc/foam.passwd
sudo foamctl admin:remove-datapath --dpid="00:00:5e:cf:6f:90:70:42" --passwd-file=/etc/foam.passwd
sudo foamctl admin:remove-datapath --dpid="00:64:08:17:f4:b3:5b:00" --passwd-file=/etc/foam.passwd

After:

[09:58:39] jbs@rci-hn:/home/jbs
+$ sudo foamctl admin:list-datapaths --passwd-file=/etc/foam.passwd
[
 "00:01:08:17:f4:b3:5b:00"
]

UH before:

[10:01:45] jbs@uh-hn:/home/jbs
+$ sudo foamctl admin:list-datapaths --passwd-file=/etc/foam.passwd
[
 "00:01:74:99:75:12:fe:00"
]

Nothing to do there.

FIU before:

[10:02:14] jbs@fiu-hn:/home/jbs
+$ sudo foamctl admin:list-datapaths --passwd-file=/etc/foam.passwd
[
 "00:01:74:99:75:24:61:00"
]

Nothing to do there either. (Also, it occurred to me that FIU has an active non-GPO FOAM admin, so if we did need to do anything there, I'd have asked him. But we don't.)

So, that's it for this one.
