code (common_utility)

if reboot and (req_args or req_remove_args):

Reboot the host for the kernel command to reflect

if reboot_cmd: raw_pty = self.cv_SYSTEM.console.get_console()
raw_pty.sendline("reboot") raw_pty.expect("login:", timeout=900)

After the first reboot, framework re-establishes console/SSH.

When try to reboot a 2nd time, self.cv_SYSTEM.console.get_console() is giving stale or HMC session, not the OS console.

So Adopt these changes in commonUtility

while reboot

1)Close stale console

2)Reopen it

3)Then reboot

Code changes to

if reboot and (req_args or req_remove_args):
if reboot_cmd:
# Always reopen console fresh to avoid stale session after first reboot
self.cv_SYSTEM.console.close() # <-- add this
raw_pty = self.cv_SYSTEM.console.get_console()

    raw_pty.sendline("reboot")
    login_patterns = [
        "login:", "root login:", "Ubuntu login:", "Password:",
    ]
    raw_pty.expect(login_patterns, timeout=900)

After changing the commonUtility hitting another issue

On 1st reboot getting warning log >>>>> Bad file descriptor Error below

Before calling self.cv_SYSTEM.console.close() ,must stop the SOL reader thread cleanly

So added exception in OpTestSOL.py --> Done changes
