RAID Type | SVC RAID Type: Striped, Mirrored |
Cluster | 2-8 nodes comprise a cluster; 2 nodes comprise an I/O group |
MDisk Group ID | The name of the MDisk group |
Capacity | Total VDisk (LUN) capacity |
Copy Capacity | Copy capacity includes mirrors |
Real Capacity | Allocated VDisk capacity; the capacity that is available to hosts |
Used Capacity | Amount of the allocated VDisk capacity (real capacity) that is used |
Free Capacity | Free = Capacity - Real Capacity |
Mirrored | Indicates if this LUN has a mirror |
Space Efficient | Indicates if this is a thin-provisioned LUN |
IO Group Name | The name of the I/O group to which this VDisk belongs |
Estimated Used | From the host’s perspective, the amount of storage used |
Estimated Available | From the host’s perspective, the amount of available storage |
Host | Hosts that have storage allocated from this LUN |
Host LUN | The name of the host to which storage from this LUN was allocated. Click on a host link to launch the

Mount Point | Mount point of the filesystem |
Filesystem | The host’s filesystem or drive name to which the LUN maps. LUNs simply appear as disks to hosts. |
Volume Group | Volume group using storage from this LUN |
Host Storage Domain | A logical group of LUNs that can be accessed by multiple hosts through the same physical storage port, with each host accessing its unique LUN.
