Sun Proprietary/Confidential: Internal Use Only

Note that in the

Class

and

State

fields, the virtualization engines are presented as

two primary

ONLINE

devices. The current Sun StorEdge Traffic Manager software

design does not enable you to manually halt the I/O (that is, you cannot perform a
failover to the secondary path) when only primary devices are present.

Manually Halting the I/O

As an alternative to using the Sun StorEdge Traffic Manager (MPxIO) software, you
can manually halt the I/O using one of two methods:

Quiesce the I/O

Unconfigure the

c2

path

These methods are explained in the following sections.

To Quiesce the I/O

1. Determine the path you want to disable.

2. Type:

To Unconfigure the

c2

Path

1. Type:

# cfgadm -c unconfigure

device

# cfgadm -al
