acp.[domain,netmask] secret decoder ring needed

[jaherring]

I need to change the IP used by ACP.  Unfortunately, in 7.3.5P1 at least, this seems annoyingly obscure.  Specifically,

netapp1b*> options acp
acp.domain                   16099520  
acp.enabled                  on        
acp.netmask                  16580607  
acp.port                     e4a    

Exactly what version of Rosetta Stone do I need to understand what the 'acp.domain' and 'acp.netmask' are?  Or, rather, how to put the one I want to use in this format?

When I first enabled the option it ran through a wizard, but I cannot seem to find a way to restart that wizard.  "options acp.enabled off" and "options acp.enabled on" do not do the trick.

The IP/netmask used originally above was 192.168.254.0 and 255.255.252.0, but I want to change it.

according to acp.domain, it is set to 192.168.245, not to 192.168.254. 192.168.254 would be 16689344.

Convert dotted-decimal to 32 bit integer by placing bytes right-to-left and you get option values. I.e. 192.168.254 == 0xc0.0xa8.0xfe => 0xfea8c0 == 16689344.

I do not know if it safe to play with these options. But of course we do need some official procedure to change ACP network.

You should be able to run the following commands, and it will run you back through the ACP setup process:

filer1> options acp.enabled off

filer1> options acp.enabled on

After re-enabling ACP, the setup process should prompt you on whether or not you want to make changes to the curent config.

This encoding is strange but it's works fine.

For 192.168.1.0,  I use acp.domain = 16777215

For 255.255.255.0, I use acp.netmask = 108736

The official procedure from our technical account manager :

A slight correction to the above, you got the domain and netmask numbers the wrong way around.

It should be:

for ACP domain:  192.168.1.0,   use  acp.domain  108736

for ACP netmask: 255.255.255.0, use  acp.netmask 16777215

Below shows the change, of course this should be done to both controllers on your filer and it takes a minute or 2 for "ACP Connectivity Status: Full Connectivity" to be restored.
