If the raid controller module does not own the virtual disk, it rejects the request. what are dell's recommendations for the hardware_handler and prio settings in multipath.conf
若主机ESX 4.0及之后版本,Failover模式只支持4 (ALUA) 路径选择策略 最近使用MRU (VMW_PSP_MRU) 在AP模式(Failover mode=1)下的推荐配置,也是默认配置。 选择 ESX/ESXi主机最近用于访问指定设备的路径。 如果此路径不可用,则主机会切换到替代路径。

This alert pertains to vmware vsphere (esxi) hosts default multipathing settings and how the addition of alua capabilities added in storage center os version 6.6 and later requires host configuration changes to remain within best practices. The lun trespass operation occurs for several reasons When this occurs, the owned luns are trespassed to the other sp Unity leverages asymmetric logic unit access (alua) for host access
