![]() You can obtain the ASL installation package for Huawei storage from. You are advised to install the latest version of ASL. When discovering devices, ASL implements hardware-specific logic to discover device properties. ASL is a shared library that can be dynamically loaded. For details on how to install Veritas Storage Foundation 7.3.1, see the Veritas Storage Foundation Installation Guide.Īfter installing Veritas Storage Foundation, install Array Support Library (ASL), which provides array-specific support for DMP. In this document, installing Veritas Storage Foundation 7.3.1 in RHEL 7.4 is used as an example. ![]() For details, contact Huawei engineers.ĭMP is generally integrated in the Veritas Storage Foundation/InfoScale software package and is used together with the Veritas Volume Manager (VxVM) and Veritas File System (VxFS). If the number of online ports is greater than the allowed value, paths may not be properly identified. ![]() If DMP 7.x is used and Host Access Mode is set to Asymmetric, the maximum number of online FC and Ethernet ports supported by a single storage system or two HyperMetro storage systems is limited because the default RTPG buffer length of Veritas VxVM (DMP) is 255.If you do not use the recommended configurations, DMP may fail to identify and process paths properly.To change the LUN mapping on the storage system, including but not limited to changing the host LUN ID, changing the port online, and removing and adding a LUN, follow the instructions in LUN Information Fails to Be Updated After LUN Replacement to correctly change the LUN mapping.If you configure the initiator for the first time, restart is not needed. If the host is running services, stop the services and export the disk group before restarting the host. If a LUN has been mapped to a host, you must restart the host for the configuration to take effect after you modify Host Access Mode or Preferred Path for HyperMetro.Use Huawei Storage Interoperability Navigator to query the combinations supported by DMP.
