Chapter 3. SVA Path Operation 23

Understanding the setsp -a Screen

Use the setsp -a command to display the default path

configurations.

Figure 3-1 Sample Output of setsp -a Command

The column headings identify the various fields on this screen, the

last seven of which are user-configurable parameters for the

device. The

setsp -a output fields (with their default values,

when applicable) are described below. The commands used to

change the default settings are described in the following section.

•

spd is the SVA Path driver number, an ID assigned to the

device by SVA Path and the name of the spd special device

file created by SVA Path to access the storage. The spd

device is displayed in the form spdN = cXtYdZ, and

provides the spd number (

N in the spdN field) and the virtual

device name (in the format cXtYdZ). This device number

also appears in errors reported in the

/var/adm/syslog/syslog.log file.

•

Path/disk shows the device names and disk numbers for

each of the redundant physical paths to the device. Their

appearance in the

setsp -a output facilitates interpreting

these events in terms of the spd device names by which

applications access devices. This field shows the disk

number in the form of cXtYdZ.
