MPXIO not Multi-pathing Newly Added LUNs

(Doc ID 1678220.1)

Last updated on JUNE 06, 2014

Applies to:

Solaris SPARC Operating System - Version 10 3/05 to 11 11/11 [Release 10.0 to 11.0]
Information in this document applies to any platform.

Symptoms

When adding new LUNs from an IBM DS8300 they are showing up in format as 4 separate disks rather than a single MPXIO LUN.
LUNs from the same array are properly multi-pathed.

Changes

Some LUNs are used for DR.  99% of the time these LUNs are read / write prohibited from the DS8300 as they are being mirrored from another server.  

In DR , break the mirror and read/write enable the LUNs to this host.   But MPXIO didn't mutlipath them and in format they showed as 4 separate LUNs.    


A current example is this test LUN allocated to the server server01
