CA Privileged Identity Manager Tech Tips by Toshiyuki Hatakeyama, Principal Support Engineer for 07/21/2016.
CA Privileged Identity Manager(a.k.a CA PIM) use canonical name for control. for example, TERMINAL class or network class.
PIM get canonical host name by OS name resolution. on Windows 'ping -a hostname' command can provide canonical name. But on UNIX, ping command does not have -a option.
You can use sehostinf which is internal utility. This command returns canonical hostname simple.
Usage:
/opt/CA/AccessControl/lbin/sehostinf -n hostname
