0

Method used to query the relationship between disks on the Linux host and LUNs on the storage array:
1. Run lsscsi on the host to query disks mapped on the storage array. You can obtain the host LUN ID corresponding to disks.
2. Obtain the host LUN ID from the array mapping. Check whether it is the same as that obtained on the host.

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.

How to query the corresponding relationship between a data disk and a LUN?
1.Log in to the CLI. 2.Run the storage command to go to the Storage management mode. 3.Run the disk list detail command. 4,View the end digit of the serial number of a data disk. The end digit is the LUN ID. Assume that the serial number of a data disk ends with 1, the data disk corresponds to the LUN whose ID is 1.
