PRIMECLUSTER Global Link Services 説明書 4.1 (伝送路二重化機能編) (Linux版)

3.6.9.1 NIC切替方式の設定内容

NIC切替方式運用時のスクリプトファイル呼出形式および定義ファイルサンプルを以下に示します。

(1) IPアドレス活性、非活性時

【スクリプト呼出形式】

/bin/sh shaX param1 param2 param3 param4

param1

activate：活性
inactivate：非活性

param2

before：活性/非活性の前
after：活性/非活性の後

param3

ifname：物理インタフェース名

param4

inet6：アドレスファミリ（IPv6の場合のみ）
※IPv4の場合 param4 はありません。
