提供程序脚本配置和Ansible攻略手册

PDF

在本文档中的示例部署和工作流执行期间、我们将使用以下提供程序配置文件、执行脚本和Ansible攻略手册。

示例脚本按原样提供、NetApp不支持。您可以通过电子邮件发送电子邮件至：mailto：ng-sapcc@netapp.com ng-sapcc@netapp.com^请求最新版本的脚本。

提供程序配置文件netapp_clone.conf

此时将按照中所述创建配置文件 "SAP Lama文档—配置SAP Host Agent注册脚本"。此配置文件必须位于安装了SAP主机代理的Ansible控制节点上。

已配置的操作系统用户 sapuser 必须具有执行脚本和所调用的Ansible攻略手册的适当权限。您可以将脚本放置在通用脚本目录中。SAP Lama可以在调用脚本时提供多个参数。

除了自定义参数之外、 PARAM_ClonePostFix， PROP_ClonePostFix， PARAM_ClonePostFix，和 PROP_ClonePostFix、可以移交许多其他人、如中所示 "SAP Lama文档"。

root@sap-jump:~# cat /usr/sap/hostctrl/exe/operations.d/netapp_clone.conf
Name: netapp_clone
Username: sapuser
Description: NetApp Clone for Custom Provisioning
Command: /usr/sap/scripts/netapp_clone.sh --HookOperationName=$[HookOperationName] --SAPSYSTEMNAME=$[SAPSYSTEMNAME] --SAPSYSTEM=$[SAPSYSTEM] --MOUNT_XML_PATH=$[MOUNT_XML_PATH] --PARAM_ClonePostFix=$[PARAM-ClonePostFix] --PARAM_SnapPostFix=$[PARAM-SnapPostFix] --PROP_ClonePostFix=$[PROP-ClonePostFix] --PROP_SnapPostFix=$[PROP-SnapPostFix] --SAP_LVM_SRC_SID=$[SAP_LVM_SRC_SID] --SAP_LVM_TARGET_SID=$[SAP_LVM_TARGET_SID]
ResulConverter: hook
Platform: Unix

提供程序脚本netapp_clone.sh

提供程序脚本必须存储在中 /usr/sap/scripts 在提供程序配置文件中进行配置。

变量

以下变量在脚本中进行了硬编码、必须进行相应调整。

PRIMARY_CLUSTER=<hostname of netapp cluster>
PRIMARY_SVM=<SVM name where source system volumes are stored>

证书文件 PRIMARY_KEYFILE=/usr/sap/scripts/ansible/certs/ontap.key 和 PRIMARY_CERTFILE=/usr/sap/scripts/ansible/certs/ontap.pem 必须按照中所述提供 "NetApp Ansible模块—准备ONTAP"。

如果不同的SAP系统需要不同的集群或SVM、则可以在SAP Lama提供程序定义中将这些变量作为参数添加。

功能：创建清单文件

要使Ansible攻略手册的执行更具动态性、请使用 inventory. yml 文件会即时创建。在变量部分中配置了一些静态值、而在执行期间动态创建了一些静态值。

功能：运行Ansible攻略手册

此功能用于将Ansible攻略手册与动态创建的一起执行 inventory.yml 文件攻略手册的命名约定为 netapp_lama_${HookOperationName}.yml。的值 ${HookOperationName} 依赖于Lama操作、并由Lama作为命令行参数进行移交。

主部分

本节包含主要执行计划。变量 ${HookOperationName} 包含Lama替换步骤的名称、由Lama在调用该脚本时提供。

系统克隆和系统副本配置工作流的值：
- 克隆卷
- PostCloneVolumes
系统销毁工作流的价值：
- ServiceConfigRemoval
系统刷新工作流的价值：
- ClearMountConfig

HookOperationName =克隆卷

执行此步骤后、将执行Ansible攻略手册、从而触发Snapshot副本和克隆操作。卷名称和挂载配置由SAP Lama通过变量中定义的XML文件传递 $MOUNT_XML_PATH。此文件已保存、因为此文件将在步骤的稍后部分使用 FinalizeCloneVolumes 以创建新的挂载点配置。卷名称将从XML文件中提取、并对每个卷执行Ansible克隆攻略手册。

在此示例中、作为实例和中央服务共享同一个卷。因此、只有在使用SAP实例编号时才会执行卷克隆 ($SAPSYSTEM)不是 01。在其他环境中、这可能有所不同、必须相应地进行更改。

HookOperationName = PostCloneVolumes

在此步骤中、将显示自定义属性 ClonePostFix 和 SnapPostFix 并维护目标系统的挂载点配置。

在期间停用系统时、自定义属性稍后会用作输入 ServiceConfigRemoval 或 ClearMountConfig 阶段。系统用于保留在系统配置工作流期间指定的自定义参数设置。

此示例中使用的值为 ClonePostFix=_clone_20221115 和 SnapPostFix=_snap_20221115。

卷 HN9_sap、动态创建的Ansible文件包括以下值： datavolumename： HN9_sap， snapshotpostfix: _snap_20221115，和 clonepostfix: _clone_20221115。

这将导致卷HN9_SAP上的快照名称 HN9_sap_snap_20221115 以及创建的卷克隆名称 HN9_sap_clone_20221115。

可以使用任何自定义属性来保留配置过程中使用的参数。

挂载点配置将从中的Lama移交的XML文件中提取 CloneVolume 步骤。。 ClonePostFix 添加到卷名称中、并通过默认脚本输出发送回Lama。中介绍了此功能 "SAP注释1889590"。

在此示例中、存储系统上的qtree是在单个卷上放置不同数据的常用方法。例如： HN9_sap 保存的挂载点 /usr/sap/HN9， /sapmnt/HN9，和 /home/hn9adm。子目录的工作方式相同。在其他环境中、这可能有所不同、必须相应地进行更改。

HookOperationName = ServiceConfigRemoval

在此步骤中、负责删除卷克隆的Ansible攻略手册正在运行。

卷名称由SAP Lama通过挂载配置文件和自定义属性进行传递 ClonePostFix 和 SnapPostFix 用于传递系统配置工作流期间最初指定的参数值(请参见上的注释 HookOperationName = PostCloneVolumes）。

卷名称将从xml文件中提取、并对每个卷执行Ansible克隆攻略手册。

在此示例中、作为实例和中央服务共享同一个卷。因此、只有在使用SAP实例编号时才会执行卷删除 ($SAPSYSTEM)不是 01。在其他环境中、这可能有所不同、必须相应地进行更改。

HookOperationName = ClearMountConfig

在此步骤中、负责在系统刷新工作流期间删除卷克隆的Ansible攻略手册正在运行。

卷名称由SAP Lama通过挂载配置文件和自定义属性进行传递 ClonePostFix 和 SnapPostFix 用于传递系统配置工作流期间最初指定的参数值。

卷名称将从XML文件中提取、并对每个卷执行Ansible克隆攻略手册。
