Sun StorEdge 3900 and 6900 Series Troubleshooting Guide • March 2002
Note that in the
Class
and
State
fields, the virtualization engines are presented as
two primary/ONLINE devices. The current Sun StorEdge Traffic Manager 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.
Alternatives to Sun StorEdge Traffic Manager
As an alternative to using Sun StorEdge Traffic Manager, you can manually halt the
I/O using one of two methods: quiesce I/O and unconfigure the c2 path. These
methods are explained below.
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
