Usage Guidelines

  • A target LUN can not be added to a LUN Copy which is in the state of copying or pause.
  • The data of a source LUN overwrites that of a target LUN upon the start of a LUN copy task.
  • Before running this command, ensure that the selected source and target LUNs are exactly the ones you want to use for a remote LUN copy task, and that no host is accessing the target LUN.
  • Different LUN copies cannot share the same target LUN.

Example

Add a target LUN on a third-party storage system whose WWN is "60:02:2a:11:00:0b:81:68:00:02:93:94:00:00:00:11" to LUN copy "0".

WARNING: You are about to build a LUN copy relationship between source LUN and target LUN. After this operation, the data on the target LUN will be overwritten by the data on the source LUN. 
Suggestion: Before performing this operation, ensure that the selected source and target LUNs are correct, and the target LUN is not being read or written by hosts.
