适用于

  • 用于 SRM 2.0 版的存储复制适配器

解答

  • 在故障转移操作期间、 SRM 将开始编译来自灾难恢复站点上 ESXi 主机的启动程序列表。在 SRM 日志中,这些事件可能类似于以下内容:

2016-07-22T13:16:30.626-04:00 [04464 verbose 'Storage' opID=] Retrieved VM Kernel IP address
'' for host ''
2016-07-22T13:16:30.626-04:00 [04464 verbose 'Storage' opID=] Retrieved VM Kernel IP address
'' for host ''
2016-07-22T13:16:30.626-04:00 [04464 verbose 'Storage' opID=] Retrieved VM Kernel IP address
'' for host ''
2016-07-22T13:16:30.626-04:00 [04464 verbose 'Storage' opID=] Retrieved FC HBA 'vmhba1' for host ''
2016-07-22T13:16:30.626-04:00 [04464 verbose 'Storage' opID=] Retrieved FC HBA 'vmhba2' for host ''
2016-07-22T13:16:30.626-04:00 [04464 verbose 'Storage' opID=] Retrieved FC HBA 'vmhba1' for host ''
2016-07-22T13:16:30.626-04:00 [04464 verbose 'Storage' opID=] Retrieved FC HBA 'vmhba2' for host ''

  • SRM 会将这些启动程序添加到“访问组”中:

2016-07-22T13:16:30.626-04:00 [04464 verbose 'Storage' opID=] Added
initiators to access group 'domain-***':
--> [{FC: 20:00:00:***}, {FC: 20:00:00:*****}, {FC: 20:00:00:*****},
{FC: 20:00:00:*****}, {FC: 20:00:00:*****}, {FC: 20:00:00:*****}, {FC:
{NFS:****}, {NFS: ****}, {NFS: ****}, 

  • 然后,在执行故障转移操作之前将此“访问组”传递给 SRA :

--><AccessGroups>
--><AccessGroup id="domain-c91">
--><Initiator id="20:00:00:*****" type="FC"/>
--><Initiator id="20:00:00:*****" type="FC"/>
--><Initiator id="****" type="NFS"/>
--><Initiator id="****" type="NFS"/>
--></AccessGroup>
--></AccessGroups>

  • SRA 将确定目标文件管理器上是否存在与要传递给它的 iSCSI 或 FCP 启动程序相匹配的现有启动程序组。如果存在匹配的启动程序组、 SRA 将重新使用它。如果现有启动程序组与 SRM 传递给 SRA 的“访问组”不匹配,则 SRA 将创建一个新启动程序组。
  • 如果 iSCSI 和 FCP 启动程序都存在于 SRM 的访问组中、则 SRA 将检查是否存在匹配的 iSCSI 启动程序组和匹配的 FCP 启动程序组。
