LUN Configuration and Security Manager XP user guide for the XP12000/XP10000/SVS200 59

• LUN: LUNs assigned to logical volumes. LUNs (logical unit numbers) are addresses assigned to logical

units (LUs), which are logical volumes that open-system hosts can access. If no paths are defined, the

other columns on the right are blank.

• CU:LDEV: CU image numbers appear on the left of the colon. LDEV numbers appear on the right of the

colon. The combination of a CU image number and an LDEV number is used to identify a logical

volume.

If an LDEV number ends with #, the logical volume is an external LU.

If an LDEV number ends with V, the logical volume is a virtual volume.

• Emulation: Logical volume’s (or logical device’s) emulation type.

For CV volumes, CVS appears on the right of the emulation type.

For LUSE volumes, an asterisk (*) and a number appear on the right of the emulation type. For

example, OPEN-9*3 indicates that three OPEN-9 volumes are combined.

• Capacity: Logical volume’s size.

• RAID: Logical volume’s RAID level.

If the logical volume is an external or virtual volume, the RAID column displays a hyphen (-) instead of

the RAID level.

• Paths: Number of alternate paths, if any.

• VMA: Access Attribute: Logical volume’s access attribute. If a VMA is set on a logical volume, VMA:

appears at the beginning of the access attribute. If extents are set on a logical volume, VMA(Ext):

appears at the beginning of the access attribute.

The following appear below the table:

• Selected LUNs: Number of LUNs selected in the table.

• Remaining LUNs (Port): Number of LUNs to which no LU path has been defined.

Indicates the number of LU paths you can add to the port specified in the tree.

• Remaining LUNs (GRP): Number of LUNs to which no LU path has been defined.

Indicates the number of LU paths you can add to the host group specified in the tree.

Lower-left list

The WWN name table or iSCSI name table appears at the lower left of the LUN Manager pane. The

WWN name table appears when you select an item related to a Fibre Channel port from the tree. The

iSCSI name table appears when you select an item related to an iSCSI port from the tree.
