Reset root password on vSphere replication Manager VMs

To reset root password on vSphere replication Manager after being locked use:

1. Restart the VM and press up and down arrow keys to go to grub console

   Use "VMRC" instead of Web console to do this

   Optionally add boot delay using https://docs.vmware.com/en/VMware-vSphere/6.7/com.vmware.vsphere.vm_admin.doc/GUID-EAAE9426-D08E-4DF1-820B-7C022C2A85FA.html so that there is gap between click power-on and the time when the machine starts to boot

2. In the grub "linux" line append:

   rw init=/bin/bash

   Press F10 to boot

3. At root prompt remount / as rw using:

   mount -o remount, rw /

4. Reset password using:

   passwd

5. Remove existing failed login count and lock information for user root using:

   /sbin/pam_tally2 -r -u root

6. Umount / and reboot using:

   umount /
   reboot -f
