Take the following actions to prepare the system for this maintenance activity.
Disabling call home

between the 30 minute minimum and the 240 minute maximum.

naviseccli eventmonitor -monitor -disableresponse -user <username> -password
<password> -scope 0 -server <serverIPaddr> -time <min>
1. Log in to the storage system or the Unisphere domain that contains the storage system.
2. From Unisphere, select System ➤ Monitoring and Alerts ➤ Notification and select the
Distributed Monitors tab.
3. Right click on the name of SP A in the list of distributed monitors for the storage system
on which you are disabling call home and select Disable/Enable Responses.
The Disable/Enable Responses dialog box appears.
4. Select the Disable Responses check box and set a time period during which responses
will be disabled for the anticipated maintenance activity. Then click OK.
In the popup that appears, click Yes to confirm.
