Oracle Home inventory is corrupted

Environment Details:
OS: Linux 5.8
Database Version: 11.2.0.3.0
Oracle Home: /u01/app/oracle/product/11.2.0.3.0
Inventory Location: $ORACLE_HOME/oraInventory
Issue: The Oracle Home was cloned from a different server, when we try to run the opatch lsinventory -invPtrLoc $ORACLE_HOME/oraInst.loc command, we were getting the error mentioned below.

-bash-3.2$ opatch lsinventory -invPtrLoc $ORACLE_HOME/oraInst.loc

List of Homes on this system:

  Home name= linux_DB__slot_ems12345_oracle_db_tech_st_11_2_0, Location= "/u01/app/oracle/product/11.2.0"
Inventory load failed... OPatch cannot load inventory for the given Oracle Home.
Possible causes are:
   Oracle Home dir. path does not exist in Central Inventory
   Oracle Home is a symbolic link
   Oracle Home inventory is corrupted
LsInventorySession failed: OracleHomeInventory gets null oracleHomeInfo

OPatch failed with error code 73

Solution: Did a through investigation and from the error noticed that it was taking a wrong oracle home. One of the suggestions was to recreate the inventory, but I checked the file /u01/app/oracle/product/11.2.0.3.0/oraInventory/ContentsXML/inventory.xml, the contents given below. I have modified the location LOC to the correct Home .i.e. /u01/app/oracle/product/11.2.0.3.0 and saved the file. When I issued the command opatch lsinventory -invPtrLoc $ORACLE_HOME/oraInst.loc again, everything was fine and I got the output.

-bash-3.2$ opatch lsinventory -invPtrLoc $ORACLE_HOME/oraInst.loc
