vdcrepadmin - command unknown

Hello.

I confused why when connecting to a PSC, using the roo user, when running the vdcrepadmin command, the system does not reccognize it.

I have installed 3 PSC servers and 2 vCenter servers.

PSC 1 and 2 used by vCenter 01. PSC3 used by vCenter02.

I use only one single sign on domain. Two sites

I try to see the agreement and eventully reconfigure it, between the different PSCs. But the system does not seem to recognize the command.

I did enabled the shell and used shell command to start the shell

shell.set --enabled true

shell

the command I try to run i this

vdcrepadmin -f showpartners -h ifqdn_psc1 -u administrator

and I get this

bash: vdcrepadmin: command not found

Thank you in advance!

Best regards!
