I'm new to NetApp and I'm looking for the procedure to change the netmask of the management interface on a NetApp FAS 2554 in a curious situation. The problem is the following. During the inizialization it has been inserted an incorrent netmask /20 instead /23. From cli, if I try to change the LIF's netmask, I get an error concerning subnet:
Error: command failed on vserver "fas2554" lif "cluster_mgmt": Cannot update LIF associations for LIF "cluster_mgmt". The netmask of the LIF ("255.255.254.0") does not match the netmask of the subnet ("255.255.240.0").
If I try to change the subnet I get an error about LIF associated:
Try removing LIF association using "network subnet remove-ranges -force-update-lifassociations true". You should then be able to modify individual LIFs and then subnet, associating LIFs with subnet again.
Createda new temporary subnet in the same ipspaceandwith the samebroadcast-domain. MovedtheLIF on the new subnet, losingthe connection. Logged on the newsubnet. Modified thenetmask of the correct subnet. Moved theLIF to the original subnet.
