[VPLEX]在两台Local之间做数据迁移

说明：

VPLEX不支持跨独立VPLEX群集的XCopy。

VPLEX只支持在Metro配置中夸两个集群的XCopy。

 

解决问题：

1.      在VPLEX上禁用storage-view的XCopy

2.      在ESXi主机上启用加速锁定（可选）

 

解决方法：

1.      通过SSH登录到VPLEX，进入vplexcli模式下，将目录切换到/clusters/cluster-1/exports/storage-views下查看storage-view

VPlexcli:/> cd /clusters/cluster-1/exports/storage-views/                                                                         

VPlexcli:/clusters/cluster-1/exports/storage-views> ls                                                                            

VMware

进入你的storage-view，并执行关闭XCopy命令

VPlexcli:/clusters/cluster-1/exports/storage-views> cd VMware/                                                                    

VPlexcli:/clusters/cluster-1/exports/storage-views/VMware> set xcopy-enabled false     

 

查看更改效果：

VPlexcli:/clusters/cluster-1/exports/storage-views/VMware> ll

最后一行显示已经关闭。

注：两台VPLEX Local都需要修改

 

2.      在受影响的ESXi主机上，启用加速锁定但禁用加速移动（XCOPY）。

用户可以选择性地禁用ESXi主机上不支持的基元，而不是禁用VAAI中的所有内容。 要更具体地了解这些变化：

HardwareAcceleratedLocking = OK; enable (atomic test and set)
HardwareAcceleratedMove = Not OK; leave disabled (clone blocks, full copy, xcopy)
HardwareAcceleratedInit = OK; enable (zero blocks, write same)
