Hello OscarTroncosod51999,

This error means the user account "a" has been locked out due to exceeding the maximum number of failed login attempts from IP 128.221.252.101. This is a security feature to prevent brute-force attacks. Now you can unlock the account, or modify the lock out setting if you feel the need to. Once of the first thing that I would do is to unlock the account if the account is needed to be used. You can unlock the account by using Navisphere cli and running the following commands:

1. Unlock the Account via Navisphere CLI (from a different workstation)

```bash

# Check the current security settings

/opt/Navisphere/bin/naviseccli -h <SP_IP> -user sysadmin -password <password> security -failedlogin -list

# Clear the failed login attempts for the user

/opt/Navisphere/bin/naviseccli -h <SP_IP> -user sysadmin -password <password> security -failedlogin -reset -user a

2. Check Lockout Policy

```bash

# View the lockout policy settings

/opt/Navisphere/bin/naviseccli -h <SP_IP> security -failedlogin -list

```

This shows:

- Maximum failed attempts allowed

- Lockout duration

- Current failed attempt count

3. Modify Lockout Policy (if needed)

```bash

naviseccli -h <SP_IP> security -failedlogin -modify -maxAttempts <number> -lockoutDuration <minutes>

```

If **all** admin accounts are locked, you may need to:

- Wait for the lockout timer to expire

- Access the **Service Port** (SPA/SPB) directly

- Contact **Dell EMC Support** for assistance with a service-level reset

@DELL-Sam L​ Thank you for your prompt response. I am very grateful for your help. I have already run the tests you sent me. What I would like to know is which service uses the username 'a' so I can fix where it is configured, ensuring it stops trying to connect with a user that does not exist anywhere. How could I trace which services are checking the status of the SPs
