Method used to configure LUN capacity expansion

You can configure LUN capacity expansion as follows:
When storage space provided to the host by the LUN cannot meet service requirements, you need to perform capacity expansion to expand the LUN's capacity.
To configure LUN expansion for a mapped LUN, configure LUN expansion on the storage system and application server. Then the expanded LUN can be used.
Storage device side: creating LUN expansion on Integrated Storage Manager (ISM)
Application server side: performing capacity expansion for the disk mapped to the LUN in CLI mode
To create LUN expansion on ISM in the storage systems of the S5000 V100R001 version, ensure that the primary and secondary LUNs are located in the same RAID group. In this case, you can avoid read and write operations across the RAID groups, and deteriorating data read and write performance.
