Usage Guidelines
This command applies only to heterogeneous takeover scenarios.
To take over heterogeneous storage arrays using Huawei storage arrays, create eDevLUNs, and map the eDevLUNs to host services, run the following commands:
- Run the "scan remote_lun" command.
- Run the "show lun_reserve general" command to query reservation information about remote LUNs that map to all eDevLUNs, or run the "show lun_reserve general edevlun_id=?" command to query reservation information about the remote LUN that maps to a specified eDevLUN.
If there is reservation information about the remote LUN that maps to the eDevLUN, run the "change lun_reserve clear" command to clear the reservation information. Otherwise, the services are interrupted.
Example
