32 The SAN Management Interface

Pathlight VX

The navigation panel string representing the Pathlight VX is analogous to the string for the Scalar i2000.

Figure 5

shows the Pathlight VX as an expanded node. It consists of one virtual library named nyvp1_lib1.

This virtual library consists of three drives. For more information about virtual libraries and drives, refer to

the Pathlight VX online help.

Device Numbering

Figure 1 on page 27 displays devices on different channels. The devices are all numbered according to a

standard scheme. To interpret the numbering, refer to Figure 6

• The number before the colon inside the square brackets represents the target ID (or SCSI ID).

• The number after the colon inside the square brackets represents the device LUN (Logical Unit

Number). This number is also sometimes referred to as the target LUN.

• The number after the dash is the assigned LUN. This number is also sometimes referred to as the

internal LUN.

Figure 6 Device numbering conventions

SCSI channels provide target space for IDs 0-15. Device LUNs 0-31 are associated with each ID. The

assigned LUN is the LUN the appliance assigns during discovery. The target ID and device LUN are

physical concepts.

The Assigned LUN is a management concept and may be manipulated by the user to create private device

maps. Refer to E

diting Device Maps on page 73, Using Scalar Firewall Manager (SFM) on page 80, Using

eVPS on page 84, or Using VPM on page 90.

Graphical Panel

On the right side of the screen, above the data panel, is a graphical representation of the networked

configuration for the selected SNC. This is the graphical panel.

For standalone SNCs or for Scalar libraries that contain a storage networking appliance, selecting the SNC,

a channel, a host, or a device in the navigation panel highlights in blue the associated symbol in the

graphical panel. Unselected SCSI channels are drawn in black. See Figure 1

on page 27. Unselected Fibre

Channels are drawn in yellow.

Selecting an i-platform library also causes a display in the graphical panel. For example, a labeled black

rectangle represents the physical library, inside of which an appropriate number of blue bars represents the

associated number of partitions. A labeled black rectangle is also used to represent the Pathlight VX

physical library, inside of which an appropriate number of blue bars represents the associated number of

virtual libraries. See Figure 4

on page 30 and Figure 5 on page 31.

Right-clicking a selected Fibre Channel, a SCSI channel, a device, or the SNC in the graphical panel

displays a command menu appropriate to the element you have right-clicked. To see these menus, refer to

the following sections:
