Syntax

Parameters

-enable

(Optional) Creates remote access accounts and enables local support assistance.

-disable

(Optional) Deletes all remote access accounts and disables local and remote support assistance.

Note: Remote Support Assistance cannot be disabled on Spectrum Virtualize for Public Cloud (SVPC) if multifactor authentication has been enabled for the superuser.

-updatetoken

(Optional) Updates the shared security token that is used for support assistance.

-remotesupport enable | disable | test

(Optional) Configures remote support assistance directly over the internet or by a configured proxy server. The values are:

enable
disable
test

No default value exists.

-idletimeout timeout_in_minutes

(Optional) Enables remote support for a limited amount of time (specified in minutes). The value must be a positive number (integer) denoting how many minutes remote support assistance is idle (and timed out). This parameter does not time out when a support session is in progress on any of your system nodes. It is renewed as many times as needed and only times out after all active sessions are terminated.

Remember: If the idle timeout expires on all participating nodes in a system, remote system support is disabled. If remote system support is disabled, remote system support is not automatically started on events that include:

When new nodes join the system.
T3 recovery procedures.
Node warm or cold starts.

If you specify -idletimeout, you must also specify -remotesupport.

Description

This command configures local or remote support assistance.

Note: Turn on both local and remote support assistance to more efficiently resolve any problems that are encountered.

Remote support assistance is available either directly over the internet or by using a proxy server. Remote system support is routed by using the proxy server if any proxy servers are configured. You must do the following to turn on remote support assistance:

Configure service IP addresses on all nodes.
Configure call home on the system.
Configure local support assistance on your system, which creates support and sets up authentication. For storage systems that have direct access to the internet, the firewall must allow outbound connections to Internet Protocol (IP) addresses 170.225.126.11, 170.225.126.12, 170.225.127.11 and 170.225.127.12 on port 22. If you must use a proxy server, configure it by using the mksystemsupportcenter command.
