VVR Event Notification

VVR provides the vrnotify utility to notify administrators of VVR specific events, such as SRL full, resynchronization complete, etc. You can receive notification for a VVR event on the Primary or Secondary node, or both the nodes in an RDS.

The vrnotify command enables you to write a script that receives VVR event notification and notifies administrators of these events through email, pager, etc. See the examples in this section to see how event notifications can also be used to keep history of various events.

If you do not specify the local_rvgname in the vrnotify command, event notification is started for all the RDSs on the local host. Use the -g option to receive event notifications for RVGs in a specific disk group.

The vrnotify command displays the VVR events until you explicitly terminate or kill the command.

To receive event notifications on the Primary or Secondary, enter the following command:

The argument local_rvgname... is a space-separated list of the names of the RVGs on the local host in the specified disk group.

The vrnotify command displays each event on a new line in the following format:

The vrnotify command displays the following types of events:

Event Type	Event Message
resync_started	Resync started on Primary RVG
resync_stopped	Resync stopped on Primary RVG
resync_paused	Resync paused on Primary RVG
lat_throttle_on	Latency throttling started
lat_throttle_off	Latency throttling stopped
lat_throttle_override	Latency throttling overridden
lat_throttle_fail	Latency throttling caused I/O failures
srlprot_throttle_on	SRL overflow protection throttling started
srlprot_throttle_off	SRL overflow protection throttling stopped
srlprot_override	SRL overflow protection overridden
srlprot_fail	SRL overflow protection caused I/O failures
srl_overflow	Replication stopped due to SRL overflow
srlprot_dcm_on	Started using DCM for SRL protection
srlprot_dcm_off	Stopped using DCM
rlk_connect	RLINK connected to remote
rlk_disconnect	RLINK disconnected from remote
srl_log_warn	SRL over 80% full
repmode_sync	Replicating in synchronous mode
repmode_async	Replicating in asynchronous mode
repibc_freeze	Replication on Secondary frozen due to IBC
repibc_unfreeze	Replication on Secondary unfrozen after IBC
rvg_pritosec	RVG role changed from Primary to Secondary
rvg_sectopri	RVG role changed from Secondary to Primary
rvg_pritoactsec	RVG role changed from Primary to acting Secondary
rvg_actsectopri	RVG role changed from acting Secondary to Primary
rlk_paused	Secondary RLINK paused because of a configuration error
ibcmsg_discarded	IBC was discarded due to timeout on the Secondary.

Example:

The following example script shows how to use the vrnotify utility to receive event notifications for the hr_rvg RDS in the hrdg disk group and send email to the alias vvradmin if the event srl_warning occurs.
