Monitor DR Appliance

Managing disaster recovery with the DR Appliance is slightly different from managing high availability, but just as simple.

The main function of the DR Appliance is to accept PN snapshots from the HA Appliance, vet them, save them to the DR Appliance, and load the most recent snapshot when the DR recovery node is needed.

To monitor from the HA Appliance:

The HA Appliance’s onQ Portal has header information that provides information about DR transfers, the HA-DR communication link, and DR disk space.

1.	Log on to the HA Appliance’s onQ Portal.

2.	Go to the DASHBOARD tab.

3.	Observe the DR Transfer status in the page header.

Hover-over the status icon to view transfer statistics:.

solid green icon	ON	DR transfers are enabled and the link between the HA and the DR is good. Also, the last transfer, if any, completed successfully.
solid red	OFF	DR transfers are disabled.
solid red	ERR	Either of the following: • the DR returned a link error. • the last transfer to the DR resulted in an error. • protection is off, but starting up. • the disk space on the DR for storing incoming transfers from HA is critically low. • the disk space on HA for storing outgoing transfers to DR is critically low.
solid yellow icon with question mark	?	onQ is unable to retrieve status information. This status can appear when screen first loads or when protection is off.
solid yellow with exclamation	WARN	The disk space on the DR for storing incoming transfers from HA is low, or the disk space on HA for storing outgoing transfers to DR is low. This status can also occur if onQ is unable to communication with the DR.
	XFER	A transfer to the DR is underway. This status might not be displayed for all transfers if the transfer is under 30 seconds and the refresh of the status display occurs between transfers.

To monitor from the DR Appliance:

In a nutshell, ensure that:

•	the connection between the two onQ Appliance is active.

•	each RN’s Last Update Time equals the corresponding PN’s Backup Status, indicating that the onQ Appliances are not synchronized.

•	there’s enough disk space to store the snapshots.

To monitor the DR Appliance:

1.	Log on to the DR Appliance’s onQ Portal.

2.	Go to DASHBOARD tab > DR STATUS page.

3.	Observe the following:

Link Status	carat is green and points upward	WAN/VPN connection to the companion HA Appliance is up.
	carat is red and points downward	WAN/VPN connection to the companion HA Appliance is down.
	icon is yellow	Usually indicates that Protection is turned off.
Link Rate		Available bandwidth (in kbps) of WAN/VPN connection to the companion HA Appliance.
RN Name		Hostname of the recovery node. In most cases this hostname is the same as the protected node’s hostname.   onQ assembles this list of recovery nodes from backup data received from the HA Appliance.
RN Ready Status	carat is green and points upward	Recovery node is ready.
	carat is red and points downward	Recovery node is not ready.
	hourglass on a yellow background	Preparing to run recovery node.
RN Running Status	carat is green and points upward	Recovery node is running and protection is turned on.
	carat is red and points downward	Recovery node is not running and protection is turned off.
Test Mode	no check mark appears	Backup is running in production mode.
	check mark appears	Backup is running in test mode.
Last Update Time		Last protected node snapshot taken from the DR Repository. RN’s Last Update Time must equal the corresponding PN’s Backup Status; otherwise the Appliances are not synchronized.
Disk Usage		Percentage disk usage of entire Appliance, and includes any recovery nodes that are running. To see the files that are consuming this space, go to the DR Repository (click on the RETRIEVAL tab).
