說明：

VPLEX不支持跨獨(dú)立VPLEX群集的XCopy。

VPLEX只支持在Metro配置中夸兩個(gè)集群的XCopy。

?

解決問題：

1.????? 在VPLEX上禁用storage-view的XCopy

2.????? 在ESXi主機(jī)上啟用加速鎖定（可選）

?

解決方法：

1.????? 通過SSH登錄到VPLEX，進(jìn)入vplexcli模式下，將目錄切換到/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

進(jìn)入你的storage-view，并執(zhí)行關(guān)閉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?????????????????????????????????????????????????????????????????????

最后一行顯示已經(jīng)關(guān)閉。

注：兩臺(tái)VPLEX Local都需要修改

2.????? 在受影響的ESXi主機(jī)上，啟用加速鎖定但禁用加速移動(dòng)（XCOPY）。

用戶可以選擇性地禁用ESXi主機(jī)上不支持的基元，而不是禁用VAAI中的所有內(nèi)容。 要更具體地了解這些變化：

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