Misinterpreting MPXIO Degraded paths in /var/adm/messages on boot for internal device with only one physical path

(Doc ID 1572402.1)

Last updated on JANUARY 28, 2016

Applies to:

Sun Storage Traffic Manager Software - Version 3.0 to 4.6 [Release 3.0 to 4.0]
Information in this document applies to any platform.


At  re/boot Solaris  /var/adm/messages file shows internal devices in degraded state when under mpxio.

The messages file will not show these devices go to a optimal state under mpxio since no additional path exists.


A X4200 has only one path to each internal drive.

Example from /var/adm/messages
