Unable to change Unit ID for Seagate storage shelf attached to Appliance

Description

User is not able to change Unit ID for Seagate storage shelf attached to Appliance.

１．Log on to Flex OS and "support elevate".

２．Check the status of SELinux by "getenforce".

３．If the result is other than disabled, make it disabled by "setenforce 0".

[root@testmachine /]# setenforce 0
setenforce: SELinux is disabled
 

４．Check the serial number and device number for storage shelf by "fwdownloader -ses".
