When upgrading PowerPath in a dual Virtual I/O (VIO) server environment, the devices need to be unmapped in order to maintain the existing mapping information.

To upgrade PowerPath in a dual VIO server environment:
1. On one of the VIO servers, run lsmap -all.
This command displays the mapping between physical, logical,
and virtual devices.

$ lsmap -all

If you do not upgrade, the PowerPath installation aborts. † If a version of MPIO framework later than the supported version is installed, PowerPath provides the option to abort the installation.

2. Log in on the same VIO server as the padmin user.

3. Unconfigure the PowerPath pseudo devices listed in step 1 by
running:
rmdev -dev <VTD> -ucfg
where <VTD> is the virtual target device.
For example, rmdev -dev vtscsil -ucfg
The VTD status changes to Defined.

differences in the PowerPath architecture. This is an expected
result and the error message can be ignored.

configuration, the following error message is displayed by
running powermt load:

Rear windshield wipers work exactly the same as front wipers. There is a parking circuit built into the motor that seats the wipers when turned off. A wiper switch and related wiring control the on-off operation and wiper speed. Finally, a leverage arm is connected from the motor to a transmission assembly, that in.
