Method used to configure the application server to use the storage space provided by storage devices when the application server is installed with the CentOS operating system:
The CentOS operating system is an open-source edition of the Red Hat operating system, which is configured in the same way as the Red Hat operating system. When the CentOS application server is connected to the storage device, configure the application server by following steps of configuring the Red Hat application server in Configuration Guide.

Method used to migrate and install storage devices
Method used to migrate and install storage devices: 1. Stop services of the host corresponding to the storage system (the host operating system is Linux, AIX, and Solaris). Determine whether services are stopped by checking on the host and storage array sides. Check whether services on the host side have been stopped: On the CLI of the host, run iostat -xt 1 to check whether I/O values of corresponding LUNs are 0. If the value is 0 within five minutes, services on the host side have been stopped. I/O values of /dev/sda, /dev/sdb, /dev/sdc, and /dev/sdd are 0, indicating that services on the host side have been stopped. Check whether services on the storage array side have been stopped: After logging in to controller A/B of the storage array in the debug mode, run iostat -xt 1. I/O values of osp_lun/osp_lun0 and osp_lun/osp_lun1 are 0, indicating that services on the storage array side have been stopped. 2. Mark optical, SAS, and network cables to be removed so that these cables can be inserted back to the original position after migration. 3. Power off the storage system. For OceanStor S2600 storage systems, remove the network cable. 4. When installing the storage system, insert optical, SAS, and network cables back to their original positions. 5. Power on the storage system.

Method to query the mapping relationship between LUNs and hosts on T series V100R005 devices
On the T series V100R005 storage system, you can view information about mapped LUNs by checking the host information. You can identify the corresponding relationship between storage systems' hosts and their connected application servers in the live network through parameters such as host names and host operating systems. You are advised to use a host name that is easy for you to recognize the host's corresponding application server. For details about how to check the host information, see Viewing Host Information.
