26 SVA Path User’s Guide

Assigning a New

Primary Path

The syntax for changing an SVA LUN’s primary data path is

setsp -l<x> -p<n>

where <x> is the spd number (see above) and <n> is the number

of the new path. The path number can be obtained by simply

counting down

setsp’s list of physical paths (in the Path/disk

column), starting from zero.

The command to change the primary path shown in Figure 3-1, on

page 23, for the SVA device with the

spd ID of 0 from its default

path through controller 7 to the path through controller 8, then,

would be:

# setsp -l0 -p1

If you run a setsp command with the verbose option (-v), the

configuration change will be displayed on screen (below)

Figure 3-2 Using setsp -p in Verbose Mode

Turning the

Exclusion Setting

Off and On

The syntax for changing the exclusion setting for a device is

setsp -l<x> -e{0|1}

where <x> is the spd number and the -e option takes one of two

arguments:

• -e0 turns exclusion off (makes the device visible to the host);

• -e1 turns exclusion on (excludes the device).

In a single-host configuration all devices should be visible to the

host. Devices can be included (or unexcluded) by using the

command.

# setsp -l all -e0

# setsp -v -l0 -p1
