    I need help regarding Pool creation in HP Aruba 8360 sw. I created a pool vlan4. But when I try to create another pool vlan7 i am getting this message 

    CoreSW(config-dhcp-server)# pool vlan13
    DHCP server instance for VRF default is enabled. Retry after disabling it.

    How i can proceed with it.

    Wanna ask whether that "dhcp-server disable" is mandatory for
    every ArubaOS switches


    only on certain model or certain version

    AFAIK other brand simply changes without need to disable dhcp first.
    Correct me if I am wrong
    Disable dhcp server will disturb service momentarily

    If you copy/paste the commands, the interruption is very minimal, would expect less than a second, and DHCP will retry if it doesn't get a response.

    You can see this as a 'safe guard' as well, because it prevents you from making changes to an operational service and potentially introducing an issue. It looks to me carefully designed like this, and you could ask the other vendors that you know that don't, why they haven't.

    An alternative solution is to use DHCP relay (ip-helper) instead of doing DHCP server on your switches. Centralized DHCP provides better visibility and control over the clients and removes 'micro management' on each of your switches, and resolves the redundancy issues that you have with local DHCP servers. And you probably never need to change the settings on the switch anymore.
