1.1 MRF Announcement Storage Unavailable Alarm Description

The severity of the alarm is Major. The alarm is issued by the MrfInstance MO.

The MRF Announcement Storage Unavailable alarm indicates that the announcement storage is not available. The alarm is ceased when the announcement storage becomes available again.

The possible alarm cause and alarm locations are explained in the table below.

Table 1 Alarm Causes
Alarm Cause	Description	Fault Reason	Fault Location	Impact
The announcement storage is not available.	Connection to the announcement storage server is lost or not configured properly.	There are network problems between the vMRF VM and the announcement storage server.	Network connection between the announcement storage server and the vMRF VM	Announcement play requests for announcement files, which are not cached locally in the vMRF VM, are rejected. Announcement files cached locally in the vMRF VM can be played. Changes to the announcement files in the announcement storage are not conveyed to the vMRF VM.
		The announcement storage directory in the storage server has been deleted.	Announcement storage server
		Configuration error in the announcement storage server or in the vMRF.	vMRF

The alarm attributes are listed and explained in Table 2.

(1) <mount_point> is the path to the announcement storage directory for announcement files.

(2) <uuid> is the identity of the Virtual Machine from which the alarm is issued.

2 Cease the MRF Announcement Storage Unavailable Alarm

See details for the MRF Announcement Storage Unavailable alarm. Check the Additional Text field of the alarm.

Check network connectivity between the vMRF VM indicated by the uuid and the announcement storage server using the ping command.

Note:

Refer to the following deployment parameter values in the announcement.conf file located in /etc/announcement_storage/:

announcement_storage_server_ip
management_net_name

Verify that the directory for announcement files is available in the announcement storage server.
1. Log in to the announcement storage server and check the availability of the directory corresponding to the deployment parameter announcement_storage_server_path.
2. If the directory does not exist, create it, otherwise continue with the next step.
Verify that the announcement storage server is configured correctly in the vMRF by checking the following deployment parameters:
- announcement_storage_server_port
- announcement_storage_server_username
- announcement_storage_ssh_private_key
- announcement_storage_server_fingerprint
Correct erroneous parameter values so that deployment parameter values match the announcement storage server configuration.
