Create the directory /archive and group owner should be the sysuser group.

Do the following steps as:

1.chgrp sysuser /archive

2.Verify using ls -ld /archive command. You should get like

drwxr-x--- 2 root sysadmin 4096 Mar 16 17:59 /archive

chgrp command is used to change the group ownership of particular files or directory.

Another way you can use the chown command.

chown root:sysuser /archive
