Cause

Starting with NetBackup software version 8.1 (NetBackup Appliance 3.1), PBX changed the location of the IPC file creation to the /var/VRTSpbx/root directory. On NetBackup appliances, the policy for the Symantec Data Center Security Agent (SDCSA) does not allow chown and chmod operations on this updated PBX path.

Solution

Emergency Engineering Binaries (EEBs) are attached to this article that address this issue for the following NetBackup Appliance releases:

• Version 3.1: NBAPP_EEB_ET3941382-3.1.0.0-1.x86_64.rpm
• Version 3.1.1: NBAPP_EEB_ET3945082-3.1.1.0-1.x86_64.rpm

Reference ET3941382 and ET3945082 for EEB details.

Before installing the EEB, note the following:

• To avoid an EEB installation failure, stop all NetBackup jobs before the installation.
• A reboot is not required after EEB installation.
• If you upgrade your appliance after installing this EEB, you must reinstall the EEB that is associated with the upgraded software version.

For instructions on installing EEBs, refer to the link in the "Related Articles" section on this page.

Veritas Technologies LLC is aware that the above-mentioned issue is present in the current version(s) of the product(s) mentioned in this article. Veritas is committed to product quality and satisfied customers.

The next NetBackup Appliance software release is targeted to include the fix for this vulnerability.

Workaround

For customers that have yet to receive and install the appropriate EEB, the workaround is to reboot the appliance.
