在不使应用程序脱机的情况下,要将现有的应用程序资源组添加到新的保护组,请在应用程序资源组处于联机状态的群集上执行以下步骤。
从一个群集上的节点创建保护组。
有关更多信息,请参见如何创建和配置 Sun StorEdge Availability Suite 3.2.1 保护组。
将数据复制设备组添加到该保护组。
有关更多信息,请参见如何将数据复制设备组添加至 Sun StorEdge Availability Suite 3.2.1 保护组。
从本地激活该保护组。
将应用程序资源组添加到该保护组。
有关更多信息,请参见如何将应用程序资源组添加至 Sun StorEdge Availability Suite 3.2.1 保护组。
在另一个群集上执行以下步骤。
检索保护组的配置。
有关更多信息,请参见如何将 Sun StorEdge Availability Suite 3.2.1 保护组配置复制到伙伴群集。
从本地激活该保护组。
此示例将在应用程序不脱机的情况下创建一个保护组。
在此示例中,apprg1 资源组在 cluster-paris 群集上处于联机状态。
在群集 cluster-paris 上创建保护组。
在该群集中某个已运行应用程序资源组的节点上,检查和修复资源组和与资源组具有关联的设备组之间可能存在的 Nodelist 不一致性。
创建具有匹配 Nodelist 的保护组。
phys-paris-1# scrgadm -pvv -g apprg1 | grep Nodelist (apprg1) Res Group Nodelist: phys-paris-1 phys-paris-2 phys-paris-1# scconf -pvv | grep "avsdg.*group node list" (avsdg) Device group node list: phys-paris-2, phys-paris-1 |
此处,设备组节点列表的顺序不同于资源组节点列表的顺序。可按如下所示更改设备组节点列表的顺序:
phys-paris-1# scconf -c -D name=avsdg,nodelist=phys-paris-1:phys-paris-2 |
您还可以对资源组的节点列表进行更改以满足要求。
创建的保护组具有与资源组和设备组的 Nodelist 相同的 Nodelist:
phys-paris-1# geopg create -d avs -p Nodelist=phys-paris-1,phys-paris-2 \ -o Primary -s paris-newyork-ps avspg phys-paris-1# Protection group "avspg" has been successfully created |
将 Sun StorEdge Availability Suite 3.2.1 设备组 avsdg 添加到该保护组。
phys-paris-1# geopg add-device-group -p Local_logical_host=lh-paris-1 \ -p Remote_logical_host=lh-newyork-1 -p Enable_volume_set=True avsdg avspg |
检验是否已创建了数据复制资源组和轻量资源组以及它们是否已联机。此外,还需检验是否已通过将 Enable-volume-set 属性设置为 True 而启用了 Sun StorEdge Availability Suite 3.2.1 卷集。

将已联机的应用程序资源组添加至该保护组。
phys-paris-1# geopg add-resource-group apprg1 avspg Following resource groups were successfully inserted: "apprg1" |
