7 Troubleshooting

This chapter lists the known issues in the HP Storage plug-in and their workarounds.

Q1. The list_app command does not list the EAR file after deployment.

A1. This occurs due to timeout during deployment in the environment. The current default timeout is 15 seconds.

Perform the following steps to increase the default timeout to an appropriate value:

1.Login to NetWeaver Administrator (NWA) portal.

2.Click Availability and Performance→System Overview→AS Java, and then click Nodes.

3.Click Started, and select Manage Java Server nodes.

4.On the Start & Stop: Java instances page, click the Java Instances tab, and then click More Actions→View System Properties.

5.On the Java System Properties: Overview page, navigate to the Services tab under Details for the instances of the selected Java.

6.Select Timeout, and click Modify under the Extended Details section for Timeout. Enter a higher value as appropriate.

Q2. Failure with the NOT_AUTHENTICATED message.

This error might occur due to any of the following reasons:

•Invalid credentials provided for the HP Storage Provider—re-enter the credentials, and test the configuration.

•A timeout between the SAP LVM adapter and the HP Storage Provider makes the current session invalid. Perform the following steps to increase the timeout to an appropriate value:

1.Navigate to <Installation Directory>/Storage/JBoss/standalone/ configuration/standalone.xml

2.Under <system-properties>, add the following:

<property name="Authentication.SessionTimeoutInSeconds" value="" />
