hi @marce1000 ;

thanks for link , but the solution given for forget shell password are applicable for virtual solution not for physical appliance

 - You may then have to re-install the appliance from scratch, make sure that a known shell password is configured during the installation process and restore the Prime environment from backup afterwards,.

Hi @marce1000 ;

thanks so much for your help i greatly appreciate it 

after contacting the support TAC , i solved the issue as follows

1-     Please use CENT-OS 7.x, Red hat Linux 7.x  ISO file only for recovering PI shell password. Do not 6.x  or 5.x as described in normal shell password recovery guide as PI 3.5 use 7.5 Red hat linux whose partition is not able to determine by older CENT-OS/REDHAT OS.

CentOS-7-x86_64-Minimal.iso

 https://mirror.umd.edu/centos/7/isos/x86_64/

Shell/root password recovery (for both on physical and virtual appliances), We need to recover the shell using the below procedure:

 https://www.cisco.com/c/en/us/support/docs/cloud-systems-management/prime-infrastructure/200760-CLI-Root-User-Password-Recovery-Process.html

2- Once booted, type "linux rescue" on prompt and hit ENTER key

3- Chose default options for language/keyboard and don't choose network option

4- You will see a message as below:

The rescue environment will now attempt to find your Linux installation and mount it under the directory /mnt/sysimage. You can then make any changes required to your system. If you want to proceed with this step choose 'Continue'. You can also choose to mount your file systems read-only instead of read-write by choosing 'Read-only'. If for some reason this process fails you can choose 'Skip' and this step will be skipped and you will go directly to a command shell.

Choose "Continue" in this screen

5- Once an existing installation is found, it will be mounted to "/mnt/sysimage" location and you will be dropped to command prompt.

6- Change root to the PI install location by using following command:

# chroot /mnt/sysimage

7- Move /storeddata/rootpatchpw

#mv /storeddata/rootpatchpw /root/

8- Now type "exit" and hit ENTER key

9- Type "reboot" and boot into PI
