Configuring an alternate index read block size for Quest DR Series systems

If a backup stored on a Quest DR Series system was performed using a non-standard block size, the scan process is unable to read the index for that backup from the device. To import indexes for such backups, you can configure an alternate index read block size in the mediamgr.cfg file.

The alternate block size is used only when index scanning fails using the current block size. When the alternate block size is used, the following message is added to the NetVault logs: “Scanned index for job '<job name>' found using alternate block size <xx>, after a failed scan using original request block size <yy>.”

To configure an alternate index read block size for Quest DR Series systems:
1
Open the file mediamgr.cfg in a text editor. You can find this file in the config directory under the NetVault installation directory.
2
Add the following lines to this file:
[Defaults:Alternate Index Read Block Size]
Type = Range
Range = 500,2147483647
Value = <Original non-standard block size>
3
Save the file.

About Network Manager

The Network Manager (nvnmgr) and Communications Manager (nvcmgr) support the inter-process messaging system. Both run as processes on Linux and UNIX systems and as threads within the nvpmgr process on Windows.

These processes perform the following functions:

•
The Network Manager and Communications Manager work in tandem to transmit inter-process messages to remote clients. While the Communications Manager handles communication between the NetVault processes on local machines, Network Manager transmits the inter-process messages to remote clients.
•
The Network Manager broadcasts availability messages, which help determine the status of the NetVault Clients.

You can modify the Network Manager settings from the Change Settings page.

 
* 
NOTE: You must restart the NetVault Service to apply any changes to the Network Manager settings.

Configuring timeout settings for Network Manager

To configure timeout settings for Network Manager:
1
In the Navigation pane, click Change Settings.
2
On the NetVault Server Settings page, complete one of the following actions:
•
To configure default settings for the NetVault Server, go to Step 3.
•
To configure default settings for a NetVault Client, click Clients. In the NetVault Clients table, select the client, and click Next.
3
Under Services, click Network Manager.
4
In the Network Manager dialog box, under Timeouts, configure the following settings.
 
Table 142. Network Manager timeout settings
Setting
Description

Time to complete a remote connection

This setting controls how long the NetVault Server tries to establish a connection with a remote client.

The default setting is 300 seconds. To change the timeout interval, type or select a new value. The timeout interval is specified in number of seconds.

Time to wait before dropping inactive connection(s)

This setting controls how long the NetVault Server waits before ending an inactive connection. It helps to reduce the amount of resources consumed by idle connections.

The default setting is 600 seconds. To change the timeout interval, type or select a new value. The timeout interval is specified in number of seconds.

Keep Alive rate

Keep-alive messages are used to verify that a connection between two NetVault machines is still intact. The keep-alive rate controls how often the server sends keep-alive messages.

The default setting is 7 seconds. To change the interval, type or select a new value. The keep‑alive rate is specified in number of seconds.

Time between availability broadcasts

The NetVault Clients broadcast availability messages at regular intervals that provide their status and location on the network. These broadcasts are used to discover new clients and update the client status on the NetVault WebUI.

The default interval for availability broadcasts is 600 seconds. To change the interval, type or select a new value. The broadcast interval is specified in number of seconds.

NOTE: Setting a very small interval can increase the network traffic, while setting a large interval can cause delays in discovering the client and updating client status on the NetVault WebUI.

Time between security broadcasts

Security broadcasts discover the password-protection status of clients, and notify whether its password has been enabled or disabled on a client. The Client Status icons on the NetVault WebUI are updated based on these broadcasts.

The default interval for security broadcasts is 600 seconds. To change the interval, type or select a new value. The broadcast interval is specified in number of seconds.

Time between availability checks

The NetVault Server performs availability checks at regular intervals to scan for changes in the network settings. If a change is detected, the server sends an interim broadcast to propagate the new settings. The broadcast system is then reset to regular pulse, reducing network traffic.

The default interval for availability checks is 10 seconds. To change the interval, type or select a new value.

You can reduce the interval between two checks to quickly detect and transmit changes. If you do not want to apply the changes immediately, use the default value or set it equal to the interval for Availability Broadcasts.
