Administrator Guide

NOTE: If the update fails, verify that you specified the correct firmware file and try the update a second time. If it
fails again, contact technical support.
7. If you are updating specific disks, repeat step 4 for each remaining disk to update.
8. Quit the FTP/SFTP session.
9. If the updated disks must be power cycled:
a. Shut down both controllers by using the PowerVault Manager.
b. Power cycle all enclosures as described in the Dell EMC PowerVault ME4 Series Storage System Deployment Guide.
10. Verify that each disk has the correct firmware revision.
Installing a security certificate
The storage system supports use of unique certificates for secure data communications, to authenticate that the expected storage
systems are being managed. Use of authentication certificates applies to the HTTPS protocol, which is used by the web server in each
controller module.
As an alternative to using the CLI to create a security certificate on the storage system, you can use FTP/SFTP to install a custom
certificate on the system. A certificate consists of a certificate file and an associated key file. The certificate can be created by using
OpenSSL, for example, and is expected to be valid. If you replace the controller module in which a custom certificate is installed, the
partner controller will automatically install the certificate file to the replacement controller module.
Install a security certificate
Perform the following steps to install a security certificate:
1. In the PowerVault Manager, prepare to use FTP/SFTP:
a. Determine the network-port IP addresses of the system controllers. See Configuring controller network ports.
b. Verify that the FTP/SFTP service is enabled on the system. See Enable or disable system-management settings.
c. Verify that the user you plan to use has manage role permissions and FTP/SFTP interface permissions. See Adding, modifying, and
deleting users.
2. Open a Command Prompt (Windows) or a terminal window (UNIX) and go to the directory that contains the certificate files.
3. Type:
sftp controller-network-address -P port or
ftp controller-network-address
For example:
sftp 10.235.216.152 -P 1022 or
ftp 10.1.0.9
4. Log in as a user with manage role permissions and FTP/SFTP interface permissions.
5. Type:
put certificate-file-name cert-file
where certificate-file-name is the name of the certificate file for your specific system.
6. Type:
put key-file-name cert-key-file
where key-file-name is the name of the security key file for your specific system.
7. Restart both Management Controllers to have the new security certificate take effect.
Using SMI-S
This appendix provides information for network administrators who are managing the storage system from a storage management
application through the Storage Management Initiative Specification (SMI-S). SMI-S is a Storage Networking Industry Association (SNIA)
standard that enables interoperable management for storage networks and storage devices.
NOTE: SMI-S is not supported for a system with 5U84 enclosures.
