Known issues in DCE

DCE release notes

DCE 8.0 known issues

We are investigating an issue where a Synchronized backup creates a Full backup and a new Full backup file.
A Synchronized backup normally appends new data to an existing Full backup, so only one backup is stored to the repository. This issue causes multiple Full backups to be stored to the same repository, and can result in using more disk space than intended.
Customers who run frequent Synchronized backups should consider disabling Synchronized backups to avoid using more disk space than expected.

We will update this page as more information is available.

• Multiple versions of DCE 8.0.0

  The current version of Data Center Expert is 8.0.0.151. Some customers received DCE 8.0.0.148 or 8.0.0.149.

  DCE 8.0.0.151 addresses the following issue in 8.0.0.149:

  Self-signed certificates cannot be removed in the System > Server Administration Settings > Server Access > Web Server display.

  Customers who updated their DCE server to 8.0.0.149 can download the 8.0.0.151 desktop client to mitigate this issue.  

  DCE 8.0.0.149 addresses the following issue in the DCE 8.0.0.148 release:

  When the Subdirectory field in the System > Server Administration Settings > Server Backup/Restore >  Backup Share Settings display contains a backslash ( \ ), the backup fails and DCE incorrectly indicates that the backup was successful.
  Replace the backslashes in the Subdirectory field with forward slashes (/) to mitigate this issue.

To update DCE 8.0.0.148 to 8.0.0.151:

Back up the DCE 8.0.0.148 server. Make sure to backup to a path that does not include a backslash.

Download DCE 8.0.0.151 at the link previously provided, deploy a new server, and restore from backup.
There is no upgrade option between DCE 8.0.0 versions.

• DCE server update process display in web client
  The DCE server update progress is not accurately displayed in the web client during the update from DCE 7.9.3 to version 8.0. The upgrade completes successfully. This will be addressed in the next release.

Other known issues

• All devices in a firmware update group are selected
  After searching for and selecting a device in the Apply Firmware Updates dialog, and then collapsing and expanding its firmware group, all the devices in the group are selected.

• Alarms do not load in the web client in Internet Explorer or Edge
  Alarms do not load when you access the web client from Internet Explorer 11 or Edge versions lower than 80.0. Alarms load as expected in Firefox and Chrome.
  Note: To update Edge to the latest version, go to https://www.microsoft.com/en-us/edge

• NetBotz rack access cards assigned to every door
  When NetBotz Rack Access is configured in Data Center Expert, the cards are assigned to every door on every pod instead of only those intended. Access is disabled for the unintended assignments.

• Both doors do not unlock on NetBotz 250 and 750

• APC 3.x device setting does not update
  Device credentials are not updated in Data Center Expert for APC 3.x devices when device configuration initiated in the APC SNMP Device Configuration option is used to change the file transfer protocol from FTP to SCP.

• Notification policy reset to default

• Some APC SNMP Device Configuration Changes in v7.3 Are Sent One Command at a Time
  Configuration changes on APC SNMP devices with firmware v6.0.0 and higher, excluding v6.0.6 - v6.1.1, are sent to the device one command at a time. It can take up to 30 seconds per user after the "Device Configuration Status" display reports the configuration is complete to apply all the options.

• APC SNMP Device Configuration File Transfer Using SCP Fails
  File transfer using SCP fails on some APC SNMP devices with firmware lower than AOS v6.3.3. For best results, enable FTP on the device, and set the protocol to FTP Only in the “Device File Transfer Settings” display before you select the devices you want to update.
  Additionally, both SCP and FTP file transfer fails on all v6.x devices with touch screens (apc_hw06_aos_xxx). See the Data Center Expert documentation in the Help Center for the most recent information on APC SNMP Device Configuration.

• Repeat Email Notifications are Sent for a Single Active Alarm

  Note: As the user types a MAC address in the search field, the search bar displays a suggestion without quotes. Using this search suggestion will return no results.

• Data Center Expert Web Client Customized Pages Unresponsive on Older Browsers
  Due to performance considerations, certain browsers may not display all the gadgets on a customized page in the Data Center Expert web client. Upgrading your browser to the latest version is recommended. If you use Internet Explorer, and cannot upgrade to a later version, consider using Google Chrome Frame to enable open web technologies.

• Data Center Expert Web Client Graphs Require Support for Scalable Vector Graphics (SVG)

  The NetBotz Web Client does not load completely when it is launched from the Data Center Expert user interface to a NetBotz appliance on the private LAN. Users accessing Data Center Expert from the public LAN must use Advanced View to connect to a NetBotz appliance on the private LAN. Alternatively, to use the NetBotz Web Client, users can connect directly to a NetBotz appliance from a system on the private LAN.

• Default Device Node Count Displayed for Data Center Expert Virtual Appliance Demo Version
  The Data Center Expert v7.2.x virtual appliance demo version supports up to 5 device nodes and one camera enabled for surveillance. To monitor 25 device nodes, displayed by default in the “License Keys” display, you must apply the virtual appliance activation license.

• Limitation on Number of Virtual Sensors
  The number of virtual sensors created can affect server performance. The recommended number of virtual sensors for a Data Center Expert server to monitor is:

  • Basic server: A maximum of 300 virtual sensors
  • Standard server: A maximum of 600 virtual sensors
  • Enterprise server: A maximum of 4000 virtual sensors

• Restore Fails When Capacity Manager v6.2 is Enabled and Capacity Tags are Configured
  When users perform a restore from a backup of an InfraStruxure Central v6.2, StruxureWare Central v6.3, or StruxureWare Central v7.0 server with Capacity Manager v6.2 enabled, the restore fails if capacity tags are configured.
  When the restore is performed on a server with the Operations key installed, the error is seen immediately. When the restore is performed on a new hardware server or virtual appliance, the server fails to boot once the Operations key is installed.
  Users must contact Technical Support to resolve this issue.

• Units in Graphs Included in Alarm Notifications are Displayed in English
  When an email, HTTP POST, or FTP alarm notification includes a graph, the units are displayed in English. The body of the email and the sensor data are displayed in the language for the locale specified in the alarm action.

• Subsequent Outlet Control Commands May Fail
  When the user performs an outlet control command, then immediately follows it with a second command, the second command may fail. The user must wait 5 – 10 seconds to issue a subsequent outlet control command.
  Users can verify the command was successful in the web interface of the device.

• Limitation on Global Device Scan Intervals
  Users cannot set their global device scan settings to less than five minutes if there are more than 2026 devices discovered on their Data Center Expert Enterprise server. This restriction is not enforced on device-specific scan settings, but APC recommends that the same policy be applied to these settings.
  For servers monitoring fewer than 2025 devices, it is recommended that the default 5-minute scanning rate be used for SNMP devices, and only adjusted for small subsets of critical devices.

• Limitation on Surveillance Settings for Cameras
  The number of cameras monitored by the Data Center Expert server, and the Camera Resolution and Target Image Capture Rate (frames per second) settings at each camera, can affect server performance. To support a large volume of surveillance data, the recommended camera settings and number of cameras for a Data Center Expert server to monitor, are:

  • Basic server: A maximum of 15 cameras at 10 frames per second, 150 fps total, and a resolution of 640x480
  • Standard server: A maximum of 125 cameras at 2 frames per second, 250 fps total, and a resolution of 640x480
  • Enterprise server: A maximum of 250 cameras at 2 frames per second, 500 fps total, and a resolution of 640x480.
