Symptoms

The method to reset these passwords depends on whether your appliance is a PowerStore T model or a PowerStore X model. Use the method that corresponds to your appliance to reset the admin or service, or both passwords.

Cause

The appliance ships with a default admin user account that lets you perform the initial configuration. It also ships with a default service user account that lets you perform specialized service functions. It is recommended that you initially configure PowerStore using the PowerStore Manager UI rather than another method such as the REST API or the CLI. Using the PowerStore Manager UI ensures that all the default passwords are changed. If you forget the new passwords, you can reset the passwords back to their default values.

Resolution


The procedure provided below was generated from the PowerStore: Security Configuration Guide.
See the PowerStore Security Configuration Guide for the most up-to-date recommendations.


Procedures:

 

Resetting admin password for PowerStore T model running PowerStore OS 2.1 or later

For a PowerStore T model appliance, this procedure is the only way to reset the password if the admin password is forgotten or unknown. This procedure resets both the service and admin passwords to their respective default values.

Steps:
  1. Locate the nonmaskable interrupt (NMI) button for the node at the rear of the appliance. The button is located on the embedded module of the node and is inside a small hole that is identified by two triangles vertically pointing at each other.

  1. Using a thin non-metallic object, press and hold the NMI button for only one or two seconds, then release it.
NOTE: Be careful. Pressing the NMI button for more than ten seconds resets (reboots) the node. Also, do not attempt another NMI password reset on the same node within two minutes.
  1. Connect to the PowerStore T model appliance using a browser to the management IP address and log in as admin with the default initial password Password123#. You should receive a prompt to reset both admin and service passwords.

  1. Change the admin password from the default to a user specified password. Clear the checkbox if you want to set the service account password to be different from the admin password.
NOTE: If you are not prompted to reset the password upon login, repeat steps 1-4 on the other node. Take this action only if you are not prompted to reset the password on the first attempt. If you are still not prompted to reset the password on each login attempt after trying once on each node, contact your service provider.
 

Resetting admin password for PowerStore T model running PowerStore OS 2.0 and earlier

A USB Thumb drive is required for resetting the Admin account password. Supported file systems include FAT32 and ISO 9660. USB port functionality will be removed in a future PowerStore OS version.

NOTE: To reset the password when the appliance is in Service Mode, use the following steps with one difference. Apply the USB reset process to each node. This action ensures that when the system is returned to Normal Mode. Upon PowerStore Manager login, you are prompted to provide a new password for both the admin and service users.
 

Steps

  1. If the USB drive is formatted, go to the next step; otherwise, use a command prompt such as: format <d:> /FS:FAT32 to format the drive. Where d: is the drive letter for the USB drive that you have inserted into your laptop or personal computer.
     
  2. Set the label with the command: label d: RSTPWD
The appliance does not mount the USB drive without the RSTPWD label. After labeling the USB drive, insert an empty file for the account passwords that you would like to reset from Command Prompt. You can reset the admin or service account password, or both.

 

  1. To create an empty file on the drive, use one or both of the following commands as needed, On the USB connected system open the Command Prompt and enter into the d:\ (pen drive connected letter) and run this commands copy NUL d:\admin; copy NUL d:\service to create the files on the USB.
  2. Insert the USB drive into the USB port of either node of the appliance, wait 10 seconds, and then remove it. The password for each account you reset is now the default value.
     
  3. Connect to the cluster through a browser using the cluster IP address and log in as admin with the default initial password, which is Password123#. A prompt to reset the admin or service passwords, or both should appear. If you prefer to reset the service password using secure shell (SSH), the initial default password for the service account is service.

Resetting admin password for PowerStore X model

For a PowerStore X model appliance, use an ISO image and mount it from vSphere. Pre-created image files can be downloaded from https://www.dell.com/support. You can also create your own image from a Linux system using the following touch commands:
NOTE: This may be downloaded using yum install -y mkisofs 
mkdir iso 
touch iso/admin 
mkisofs -V RSTPWD -o reset.iso iso

Example ISO creation

[root@computer tmp]# mkdir iso
[root@computer tmp]# touch iso/admin
[root@computer tmp]# mkisofs -V RSTPWD -o reset.iso iso
I: -input-charset not specified, using utf-8 (detected in locale settings)
Total translation table size: 0
Total rockridge attributes bytes: 0
Total directory bytes: 0
Path table size(bytes): 10
Max brk space used 0
174 extents written (0 MB)
[root@computer tmp]#		 
NOTE:
  • The ISO image, reset.iso, must reside on a datastore before it can be mounted as a virtual CD from vSphere.
  • To reset the password when the appliance is in Service Mode, use the following steps with two differences.
    • First: Upload the ISO image to the PRIVATE-XXXXXXX.A.INTERNAL datastore of the controller virtual machine (VM) itself because the public datastore is not available.
    • Second: Upload and apply the reset.iso file to both controller VM nodes A and B. This action ensures that when the system is back in Normal Mode and PowerStore Manager access is available, you are prompted to provide a new password for both the admin and service users.

 

Steps

  1. In vSphere under Storage, select your PowerStore X model appliance. For example, DataCenter-WX-D6013 > PowerStore D6013
     
  2. Under Files, select ISOs.
     
  3. Select Upload to upload the reset.iso file, either the pre-created image file from www.dell.com/support or your own image file that you created on a Linux system. The reset.iso file appears in the ISOs folder.
    reset.iso file appears in the ISOs folder
  4. In vSphere under Host and Clusters, select the primary node of the primary PowerStore X model appliance in the cluster. For example, select DataCenter-WX-D6013 then Cluster WX-D6013 and then PSTX-44W1BW2-A
     
  5. Under Summary, click CD/DVD drive 1 and select Connect to datastore ISO file. The "Choose an ISO image to mount" window appears.
     
  6. Under Datastores, click the primary PowerStore X model appliance in the cluster and select the ISOs folder. The reset.iso file should appear under Contents.
    reset.iso file appears in the select file
  7. Select the reset.iso file and click OK. Under Summary, CD/DVD drive 1 should appear as Connected for about 10 seconds, and then change to Disconnected. The cluster admin password, or service password, or both, are now reset to their default.
    CD/DVD drive 1 should appear as Connected
     
  8. Connect to the cluster through a browser using the cluster IP address and log in as admin with the default initial password, which is Password123#. A prompt to reset the admin or service passwords, or both should appear. If you prefer to reset the service password using SSH, the initial default password for the service account is service.
