Monitoring IBM TS4300/Dell EMC ML3 tape libraries not working?

Hello,

The TCP connection test is successful, which is good. Let's troubleshoot the authentication issue step by step.

**Understanding the Authentication Process:**

Our system automatically tries multiple login endpoints to detect your device type:

1. First tries `/v1/login` (IBM TS4300 endpoint)

2. If that fails with 401/404, tries `/rest/login` (Dell ML3 endpoint)

A successful response should return either:

- `{"token":"..."}` (authentication token), or

- `{"status":"success"}` or `{"status":"ok"}`

**Manual Testing:**

Please test the authentication manually using curl to see the exact API response:

**For IBM TS4300 or Dell:**

curl -k -X POST https://172.16.x.x:3031/v1/login \

 -H "Content-Type: application/json" \

 -d '{"username":"youruser","password":"yourpassword"}'

**For Dell ML3 orTS4300:**

curl -k -X POST https://172.16.x.x:3031/rest/login \

 -H "Content-Type: application/json" \

 -d '{"username":"youruser","password":"yourpassword"}'

Try both endpoints and share what they return.

**Additional Troubleshooting Steps:**

1. **Test with Administrator account:**

  If you have an administrator account, try it as well to rule out permission issues:

   curl -k -X POST https://172.16.x.x:3031/v1/login \

   -H "Content-Type: application/json" \

   -d '{"username":"admin","password":"adminpass"}'

  2. **Check account status:**

  Verify that your "monitor" user account is:

  - **Not disabled/locked** - check the user management page on the device

  - **Not expired** - some devices have account expiration policies

  - **Password is correct** - try logging into the device web UI with the same credentials

3. **Check device logs:**

  If possible, check the authentication logs on your TS4300/ML3 device to see why authentication is being rejected.

Let us know what the curl commands return.

Thank you.
