VNX5100 Password Reset

My work center has a VNX5100 that was initialized by someone in the past but was never used.  We now no longer know the username and password to login to it from unisphere.  I have searched this forum for ways to password recovery, including holding the triangle button on the back, using PPP connection through serial cable, but have not been able to get any of them to work.  Is there anyone out there who can give me some assistance with this problem?

Re: VNX5100 Password Reset

Hi Starwars80,

Now that is not good ...:-(

Please try to document every action you are doing in your IT environment. If not for yuor self, then for the poor guy who will be dealing with it after you or with you.

Please find the steps here below from EMC (https://support.emc.com/kb/15149😞

Follow these steps to recover the password on the CLARiiON and VNX array.
Alternatively you can view a video demonstration here: http://powerlink.emc.com/km/live1/en_US/Offering_Basics/Demo/video_emc280425.mp4.
You need to create a PPP connection. The following steps are for Windows 7:

1. Create the COM port modem.

     a. Click Start -> Control Panel -> Phone and Modem.

     b. Click Modem Tab and click add.

     c. On the Install new Modem Pane, select the "Don™t detect my modem" box, then click Next.

   

     There will be a pause while the models load.

     d. Select Communications cable between two computers, and then click Next.

     e. Select your COM port, click Next, and you are done.

2. Set up the PPP connection.

     a. Click Start -> Control Panel -> Network and sharing center, click Set up a new connection or network (at the bottom).

     b. On the next screen, select set up a dial-up connection and click Next.

     c. The next screen should list modems and select the Communications cable between two computers you created above.

     d. On the next screen type some numeric value for phone number, type the username and password (clariion and clariion!) and give it a name. The above connection should now appear in Network Connections, right-click it and select Properties.

     If "clariion/clariion!" is not accepted as Username and Password, try "Administrator/clariion!" as Username and password. On some storage processors, "clariion1992/clariion1992" works.

3. Once the connection is set up, modify the settings as follows:

     a. In the General tab, click configure and set Max speed to 115200 and select enable hardware flow control and Enable modem error control.

     b. In the Options tab, click PPP settings and check top two boxes are selected (LCP extensions and SW compression).

     c. In the Security tab, check Data Encryption is Optional Encryption (connect even if no encryption)" is set.

     d. In the Networking tab, check Internet Protocol Version 4 is selected.

     e. In the Networking tab, choose Internet Protocol Properties, then the Advanced button. Uncheck "Use default gateway on remote network."

     Your connection can then be accessed from Network Connections.

4. Once the PPP connection is established:

     a. Point your browser to this URL: https://192.168.1.1/setup.

     b. Click "Create a New Account."

     c. Enter a New User name and in the New Password Verification text box, type in the password again.

     d. Point your browser to this URL: http://IP_address_of_SP

     e. Log in to domain using the new username and password.

     f. From Unisphere dashboard, Go to Domain > Manage Global Users

     g. Select the user for which password needs to reset.

     h. Click  Modify and Click OK.

     i. Log out and log in to Unisphere with User whose password was changed.

     Note: You also have the option of completely resetting domain security. However, if you select this option, you will destroy ALL domain information, including domain information for the master, other arrays, and portals.

     j. Click "Reset Security" and confirm.  (You must reset security on both storage processors [SPs].)

Re: VNX5100 Password Reset

Assuming you already know how to setup a PPP connection to VNX SP:

You must use a serial connection for the
following procedure to work:

  1. Establish a PPP connection to one of the storage processors (SPs).
  2. Point your browser to this URL: http:// 192.168.1.1/setup
  3. Click "Create a New Account."
  4. Enter a user name and in the New Password Verification text box, type in the
    password again.
  5. Click "Restart Management Server."

    Note: You may need to restart Management Server on both SPs.
  6. Point your browser to this URL: http:// <IP_address_ of _SP>
  7. Log in to domain using the newly-set username and password.

    Note: You also have the option of completely resetting domain security. However, if you
    select this option, you will destroy ALL domain information, including domain
    information for the master, other arrays, and portals. If you decide to reset
    domain security, replace Step 3 with the following:

    Click "Reset Security" and confirm.  (You must reset security on both SPs.)

    Then perform all other steps as described.

Note: If the procedure does not work, connect to the master SP and rerun Steps 1 to 7.

For VNX and CX4 systems, use the following

Re: VNX5100 Password Reset

Yes, the easiest way is connecting to its Service LAN port:

With CX3/CX4/VNX’s Service LAN port (spanner icon), you can easily connect to its web console (and no need for a cross-over cable). Each Service LAN port has a fixed IP address:

SPA: 128.221.1.250, mask: 255.255.255.248

SPB: 128.221.1.251, mask: 255.255.255.248
