Call-home notifications
About call-home notifications
Call-home notifications are messages sent automatically to Dell EMC Customer Service and/or Customer Support
Representative when a serious problem occurs. Call-home notifications enable Dell EMC to pro-actively engage the relevant
personnel, or use a configured ESRS gateway to resolve the problem.
There are four levels of system events. Call-home notifications are sent only for three levels:
Table 2. Event severity and Call-home notifications
Severity Definition Impact on Performance or Availability Call-home
Critical: (1) A DU or DL is either highly probable or has
occurred.
● System unavailable.
● Severe performance degradation.
Yes
Error: (2) Possible DU or DL. Requires service
intervention.
● Limited performance impact.
● Loss of redundancy.
● Moderate risk of DU/DL.
Yes
Warning: (3) Service attention required. No urgency.
● No performance impact.
● Loss of redundancy.
● No risk of data loss or unavailability.
Yes
Info: (4) Informational event. No action is required. None. No
Refer to the SolVe Desktop Troubleshooting Procedures for a list of all events.
Many maintenance activities (such as hardware replacements) generate a flurry of call-home events. Many such procedures
include steps to temporarily disable call-home notifications during the operation.
Modify call-home and SYR
Call-home notifications and SYR settings are typically configured during system set-up.
Use the configuration event-notices-reports-config CLI command to configure the call-home notifications
and/or SYR settings if they were not configured during the initial installation.
The command runs an interview script that prompts for the required information. If either call-home notification or SYR is not
configured, interview questions to configure the service that is not configured are displayed.
If both call-home notifications and SYR settings are already configured, the current configuration information is displayed.
