What does arraycommpath do?

当我们不需要CLARIION VNX存储与主机连接的时候,可以disable arraycompath 这个参数,这样在主机侧就不会有LUNZ的设备

当需要有数据盘过去的时候,可以enable这个参数,这时候用一个LUN0的设备取代,主机侧也就不会有LUNZ的设备

The arraycommpath option enables or disables a communication path from the server to the storage system when LUN 0 is not configured on the storage system. Enabling arraycommpath from Navisphere instructs the array to present a LUNZ whenever a host LUN0 does not exist. If a host LUN0 is available to the server (LUN0 bound and no Access Logix or LUN0 in the Storage Group for the initiator), the status of arraycommpath does not matter.  If arraycommpath is not set appropriately at initial host and array configuration, the host will not be able to see the storage system or the LUNs (in which case PowerPath and failover is irrelevant).  In summary, arraycommpath does not play any role in failover.  That is done by the failovermode setting.
