2. Query whether the status of the RAID group that owns the master LUN of the extend
LUN is normal.
3. If the status of the RAID group that owns the master LUN of the extend LUN is
Fault, you can determine that the master LUN of the extend LUN is invalid.
l Cause 2: The slave LUN of the extend LUN is invalid.
1. In the navigation tree, expand the All RAID Groups node.
2. Query whether the status of the RAID group that owns the slave LUN of the extend
LUN is normal.
3. If the status of the RAID group that owns the slave LUN of the extend LUN is
Fault, you can determine that the slave LUN of the extend LUN is invalid.
