EM13c ASM Target Showing Incorrect Disk Group State when FLEX ASM is used (Doc ID 2570037.1)

Last updated on JULY 26, 2019

Applies to:

Enterprise Manager for Oracle Database - Version 13.2.0.0.0 and later
Information in this document applies to any platform.

Symptoms

In a FLEX ASM environment, the diskgroups are incorrectly shown as DISMOUNTED. Also, the underlying metric is showing them down:

emctl getmetric agent "+ASM2_node1.domain.com",osm_instance,DiskGroup_Status 
Oracle Enterprise Manager Cloud Control 13c Release 2 
Copyright (c) 1996, 2016 Oracle Corporation.  All rights reserved. 
dg_name,dg_state 
DG1,DISMOUNTED 
DG2,DISMOUNTED 
FRA,DISMOUNTED
DG3,DISMOUNTED 

However, the diskgroups are working fine on the designated nodes in a FLEX ASM environment:

[user@node1 ~]$ crsctl status resource -w "TYPE = ora.diskgroup.type" 
NAME=ora.DG1.dg 
TYPE=ora.diskgroup.type 
TARGET=ONLINE               , ONLINE               , ONLINE               , 
OFFLINE 
STATE=ONLINE on node1, ONLINE on node2, ONLINE on node3, OFFLINE 

This is because the ASM is actually running on 3 out of the 4 nodes (which is a normal behavior in a FLEX ASM setup).
