Invalid unit address in D FILES command after FDRPAS DASD SWAP

Products

• MIM Resource Sharing (MIM)

Issue/Introduction

4 LPARS in MIM complex(SYS1,SYS2,SYS3,SYS4)

SYS1 & SYS2 are in PROD sysplex

SYS3 & SYS4 are in TEST sysplex.

Recently we  used FDRPAS to move all our DASD storage to different DASD raids and unit addresses.

IPLed the SYS3 & SYS4 LPARS 

The D FILES command in SYS3 & SYS4 show the correct unit address

However, the same command in SYS1 & SYS2 continue to show the old unit addresses that no longer exist

Environment

Release : 12.5
Component : MIM

Cause

Unknown

Resolution

PTF LU06098 has been written to correct this.

Until the fix is applied, the invalid unit reference is only witnessed with a DISPLAY FILES command and is not impacting functionality.

WORKAROUND:
An IPL of the system corrects the display.

The correct unit reference will be witnessed with a DISPLAY IO command.
