asmcmd does not return error text for root user

Problem:

While running asmcmd commands via root user, error messages are not displayed. But if we run the same command via grid – it returns messages. In the following example, ORACLE_HOME is set to RDBMS home (instead of GI) and we are trying to list the file which does not exist:

[root@rac1 ~]# echo $ORACLE_HOME
/u01/app/oracle/product/19.3.0/dbhome_1

[root@rac1 ~]# echo $PATH
/u01/app/19.3.0/grid/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin

[root@rac1 ~]# asmcmd ls +demodg/orcl/tempfile/TEMP.263.10617958
<<<<<<Nothing is displayed here

When a file does not exist, ls command should display ASMCMD-8002: entry 'TEMP.263.10617958' does not exist in directory '+demodg/orcl/tempfile/' error. But in our example, it does not return anything.

In the following example, if we try to copy a file, we see a message about copying a file but actually, the file is not copied because grid user does not have permission under /u01:

[root@rac1 ~]# asmcmd cp +demodg/orcl/tempfile/TEMP.263.1061795851 /u01
copying +demodg/orcl/tempfile/TEMP.263.1061795851 -> /u01/TEMP.263.1061795851

If we run the same command via grid, we get understandable error message:

[grid@rac1 ~]$  asmcmd cp +demodg/orcl/tempfile/TEMP.263.1061795851 /u01
 ASMCMD-9463: operation failed due to lack of write permissions

Reason:

Environment variables are not set correctly. ORACLE_HOME should be pointing to GI home.

Solution:

[root@rac1 ~]# export ORACLE_HOME=/u01/app/19.3.0/grid

[root@rac1 ~]# asmcmd ls +demodg/orcl/tempfile/TEMP.263.10617958
ASMCMD-8002: entry 'TEMP.263.10617958' does not exist in directory '+demodg/orcl/tempfile/'
