You can use the "showlicense -raw" output as the license for adding to the system again.
Was it a 7400 that you have split up, or was it actually 2 x 7200 (7400 is essentially 2 x 7200 with a link cable between them and a BIOS change).
Im guessing you are using
array: 10.0.1.6
gateway: 10.0.1.1 ?
ntp: 10.0.1.10 and 11 ? (I just randomly picked 2 addresses for example, change as it should be)
dns: 10.0.1.10 and 11 ? (I just randomly picked 2 addresses for example, change as it should be)
name: testarray1
you would do the following:
Ensuring that you have both nodes connected to a switch on the correct vlan and can ping the gateway.
Code:
setnet startaddr 10.0.1.6 255.255.255.0
setnet startgateway 10.0.1.1
setnet ntp none
setnet ntp -add 10.0.1.10
setnet ntp -add 10.0.1.11
setnet dns none
setnet dns -add 10.0.1.10
setnet dns -add 10.0.1.11
setnet finish -f
setsys -name testarray1
Is this what you did?
