- Glossary of terms
● To manually place the system into maintenance mode, click Enable Maintenance. Placing the system into maintenance
mode notifies SupportAssist not to create support tickets during planned system downtime.
● To manually remove the system from maintenance mode, click Disable Maintenance.
● To manually send storage system logs to SupportAssist, click Send Logs, and click Yes on the confirmation panel.
● To check the network connection to the SupportAssist infrastructure, click Check Connection, and click Yes on the
confirmation panel.
● To clear the SupportAssist proxy settings, click Clear Web Proxy, and click Yes on the confirmation panel.
Configure SupportAssist to use a web proxy
If the storage array does not have direct access to the Internet, SupportAssist can use a web proxy to send data to technical
support .
NOTE: DNS must be configured on each controller to allow SupportAssist to work with a web proxy. To configure DNS, see
Configure DNS settings on page 46.
1. Perform one of the following actions to access the SupportAssist options:
● In the Home topic, select Action > System Settings, then click the SupportAssist tab.
● In the System topic, select Action > System Settings, then click the SupportAssist tab.
● In the Welcome panel, select System Settings, then click the SupportAssist tab.
2. On the Web Proxy Settings tab:
a. Select the Web Proxy checkbox.
b. Type the hostname IP address of the proxy server in the Host field.
c. Type the port number of the proxy server in the Port field.
d. If the proxy server requires authentication, type the credentials in the User Name and Password fields.
3. Click Apply or Apply and Close, and click OK on the confirmation panel.
Enable or disable CloudIQ
The CloudIQ feature is enabled by default on ME4 Series storage systems. To send data to CloudIQ, the ME4 Series storage
system must be onboarded to CloudIQ and SupportAssist must be enabled on the storage system.
To stop sending data to CloudIQ, without removing the storage system from CloudIQ, clear the Enable CloudIQ checkbox.
1. Perform one of the following actions to access the SupportAssist options:
● In the Home topic, select Action > System Settings, then click the SupportAssist tab.
● In the System topic, select Action > System Settings, then click the SupportAssist tab.
● In the Welcome panel, select System Settings, then click the SupportAssist tab.
2. On the CloudIQ Settings tab, select or clear the Enable CloudIQ checkbox.
3. Click Apply or Apply and Close, and click OK on the confirmation panel.
NOTE: It may take several hours for changes to the CloudIQ setting to take effect.
Changing host port settings
You can configure controller host-interface settings for ports except for systems with a 4-port SAS controller module. To enable
the system to communicate with hosts, you must configure the host-interface options of the system.
NOTE: If the current settings are correct, port configuration is optional.
For a system with a 2-port SAS controller module, host ports can be configured to use standard cables. A standard cable can
connect one port on a SAS host to one controller port, using four PHY lanes per port. Use of fan-out cables is enabled by
default. When configuring the host-interface settings for a 2-port SAS controller module, the Host Ports Settings panel displays
the following:
● Current link speed
● Cable type
● Number of PHY lanes expected for the SAS port
● Number of PHY lanes active for each SAS port
