request system software nonstop-upgrade

Syntax

Description

Nonstop software upgrade enables you to upgrade a QFabric system with minimal packet loss and maximum uptime. You should upgrade the devices in the following order: Director group, fabric controls and Interconnect devices, and network and server Node groups.

Note:

Before you perform a nonstop software upgrade, contact JTAC to perform a pre-upgrade health check on the QFabric system.

Options

package-name

Location from which the software is to be installed. For example:

  • protocol://hostname/pathname/package-name—For a software package or bundle that is to be downloaded and installed from a remote location. Replace protocol with one of the following:

    • ftp—File Transfer Protocol.

      Use ftp://hostname/pathname/package-name. To specify authentication credentials, use ftp://<username>:<password>@hostname/pathname/package-name. To have the system prompt you for the password, specify prompt in place of the password. If a password is required, and you do not specify the password or prompt, an error message is displayed.

    • http—Hypertext Transfer Protocol.

      Use http://hostname/pathname/package-name. To specify authentication credentials, use http://<username>:<password>@hostname/pathname/package-name. If a password is required and you omit it, you are prompted for it.

      Use scp://hostname/pathname/package-name. To specify authentication credentials, use scp://<username>:<password>@hostname/pathname/package-name.
