存储向Esxi集群新映射Lun，vcenter 操作重新扫描所有设备，管理界面卡死

ESXi版本多少？VMware KB提到多个主机同时分配VMFS的时候会造成主机无响应：Cluster wide storage rescan from vCenter Server causes ESXi/ESX hosts and virtual machines to become unresponsive (10390…

不过最新版本这个问题应该被修复了。如果确实版本比较旧又不方便升级的话，它有建议work around：

To work around this issue when you are unable to apply a patch:

• Run rescans from individual hosts one at a time using the vSphere Client or console. For more information, see Performing a rescan of the storage on an ESXi/ESX host (1003988).
• Disable automatic rescan from vCenter Server. For more information, see How to disable automatic rescan of HBAs initiated by vCenter (1016873).
• Reduce the number of LUNs/datastores that every host is seeing. For each host, only present the LUNs that the cluster hosts have virtual machines or RDMs on. Unpresent all the unused LUNs from the cluster.
