When using RDA for backups, only four streams are used at once

Description

When using RDA to back up 20 or more clients, in device activity, only four streams are used at once. Updating the setting in the configuration file at /config/dellrda config file from 32 streams to 512 streams and restarting NetVault services, yields the same result.

Symptom

When multiple backup jobs that target the same disk-based storage device are scheduled to start at the same time or within a small window of time, the following issues occur:

•
The target device is underused regarding the number of streams.
•
Some jobs remain in the “Waiting for media” state even if the device can run parallel jobs.
•
The completion time for small jobs increases by a few seconds or minutes.
Solution

These issues occur because the Media Manager uses a “quiesce time” setting to prevent assigning too many simultaneous jobs to a disk-based backup device. By default, the quiesce time is set to 10 seconds. Thus, after a job is assigned to a disk-based storage device, the Media Manager waits for 10 seconds before assigning the next job to the same device. You can change the default setting for quiesce time in the mediamgr.cfg file.

To change quiesce time for disk-based storage devices:
1
Open the mediamgr.cfg file in a text editor.
You can find this file in <NetVault home>\config on Windows and <NetVault home>/config on Linux.
2
Change the value for the following entry:
[Media Requests:RAS quiesce time]
Type=Range
Range=0,1000
Value=10
The default value is 10. To start the jobs at the same time, set the value to 0 (Value=0).
3
Save the file.

Note the following:

•
This setting applies to all disk-based storage devices (DR Series systems, EMC Data Domain Systems, and NetVault SmartDisk devices).
•
For shared NetVault SmartDisk devices, this value cannot be set to 0.

Unable to create large VTL on Linux

 

Description

When creating a Large_VTL on a Linux machine, the NetVault WebUI takes too long to respond and the session expires.

Symptom

On a Linux NetVault Server, when creating a Large_VTL, if the WebUI times out due to inactivity or the user closes the WebUI while the creation is still in progress, the VTL creation does not occur.

Solution

In the WebUI, add a VTL using the Re-add previously generated virtual device option.

 
* 
NOTE: This solution works only when the VTL entry is present in the "diskdevice.cfg" file under "libraries" section and when the directory is present in the mentioned path.

Browsing a folder with a large number of files times out

Description

During a restore, browsing and expanding a folder with a large number of files, such as 10,000 or more, fails.

Symptoms

After several minutes of browsing, the restore job times out, the WebUI does not respond, or the error, “The remote machine: [MACHINE_NAME] is unavailable,” appears.

Solution 1

Use Catalog Search to find the item that you want to restore.

Solution 2

Manually increase the web services physical client long timeout settings by completing the following steps:

1
In the Navigation pane, click Change Settings.
2
On the NetVault Server Settings page, under Services, click Web Service.
3
In the Web Service dialog box, configure the Physical Client Long Timeout setting to the maximum amount of 60,000 seconds.

Safe Mode in NetVault

The following error occurs when NetVault is in Safe Mode, “NetVault Server is in safe mode. Please contact your service provider.”

In this case tenant must contact MSP administrator.

The following error conditions can force NetVault to run in Safe Mode:

•
A key process such as Media Manager or Schedule Manager fails to start.
•
The PostgreSQL database is unavailable or NetVault is unable to connect to one or more databases.
•
The NetVault Server is low on disk space.

In Safe mode MSP administrator must read the message from <Installation location>\config\safemode.cfg>, after login to NetVault Server

This file keeps the cause of NetVault Server to run in Safe Mode.

The following table describes the error types and possible options to resolve the issue identified in safemode.cfg:

 
Error type
Available options

Key process failures

When NetVault enters safe mode due to this error, no options are provided to resolve the issue.

Database connection failures

Please validate PostgreSQL Service logs and resolve the issue. You can now restart the services, if issue persist contact NetVault support.

 

Low disk space issues

Reclaim space in NetVault installation location and go to restart NetVault in normal mode

•
 
•
Restart NetVault in normal mode: Once NetVault enters safe mode, it remains in this mode whether the error is resolved or not. To exit safe mode, restart NetVault in normal mode.
Stop the NetVault Process Manager and NetVault PostgreSQL database server services. Remove safemode.cfg file from the following location: <Installation location>\config\safemode.cfg> and restart NetVault PostgreSQL database server and NetVault Process Manager services.
•
Restart NetVault with diagnostic tracing enabled: For diagnostic tracing consult Quest Technical Support.
