KT-8088 Description: Isilon: Database migration requires a second reboot
  Workaround: When a User attempts to migrate a database for the first from the default location ie V:\media\media.db race conditions are created to prevent the database from connecting properly. Once the database is copied to the desired location via the DBPath registry key, a second reboot is needed to ensure services are started in the properorder and database connectivity to be restored. Additional note: All connected summits will need to be restarted too.
KT-8060 Description Channel configurations may be lost upgrading to 9.5.
  Workaround When using Siteconfig to upgrade earth-sa-2 from to, all channel lost their configurations. - Channels went from EE to PB mode - Timecode went from TOD back to INT - All channels went back to SD--most were set to 720p or 1080i - All channels lost their proxy setup settings. - The Multi-cam channel went back to a single Player/Recorder. - AMP protocol went back to VDCP Note that these settings are reverting back to defaults. Normally this should not happen for a software-only upgrade. This was kicked out of the 9.5 release because of how late it was in the program when this was first reported and the high risk of introducing new problems.
KT-2589 Description Blue screen and other difficulties in the field when changing a 9.4 Summit to have IP codec board and 9.5 software.
  Workaround None.

  Workaround To get out of the bad state, change the Video Input selection to SDI (with a valid PAL/SD signals present on the SDI inputs) and then change back to 10GigE.
KT-8100 Description Unknown transceiver warning in log with 10GigE direct-attached cables.
  Workaround The cable still functions as expected, the warning message can be ignored.

Workaround: Only two 1080p channels are supported for iSCSI connected SAN clients. Use FibreChannel connections to use 1080p on more than two channels on SAN clients. While two channels are doing a continuous record of 1080p, do not use the other two channels.
DE6954 Description: In the K2 TimeDelay application, thumbnails are not updated.
Workaround: None. Thumbnails are no longer updated as records continue in K2 TimeDelay.

Workaround: None.
DE9664 Description: 6-in/2-out performance is slow when using ShareFlex on K2 Summit 3G systems with hard drives.
Workaround: Ensure your hardware is able to support this feature. You may also try the following to bring the system back into its operational rating:
  • Use split audio on the triple Multi-Cam channels instead of no split audio
  • Drop the video bit rate to 50Mbps
  • Do not use ShareFlex
  • Use SSDs instead of hard drives
DE11433 Description: When running the Summit Diagnostics application, the message RESULT: CodecMezz Memory Test FAILED is false. There is nothing wrong with tested component.
Workaround: Contact Grass Valley Support to install an update to the Summit Diagnostics application.

Proxy/live streaming

ncb00041093 Description: Live streaming can fail when the K2 Summit system's IP address is changed.
Workaround: On the K2 Summit system navigate to V:\live streaming and use Notepad or a similar text editor to open a *.sdp file. Check the first IP address listed in the file, on the o= line. If it is not the K2 Summit system's Control Connection IP address, delete the *.sdp files in the directory and restart the K2 Summit system.
ncb00061128 Description: Remote desktop connections cause live streaming errors and audio/video sync problems.
Workaround: Do not use Remote Desktop on K2 Summit systems that are generating live streams. To restore live streaming audio/video sync, disable the proxy recording and live streaming for that channel, then re-enable live streaming.


ncb00003885 Description: If uninstalling or installing K2 client software while applications or connections to AppService are open, the installation program becomes unresponsive.
Workaround: To prevent the problem from occurring, shutdown all applications and connections before uninstalling or installing. Then after all applications are shutdown, use Task Manager to stop AppService.
ncb00040814 Description: Error messages appear during Generic iSCSI software install. This occurs when doing a manual (not SiteConfig) install on a Windows 7 PC. The error messages are similar to "The installation of VS2005.762 appears to have failed..." and "Setup could not find the update.inf file...".
Workaround: Ignore the error messages and continue with installation. The software installs successfully. The error messages are caused because the installation program tries to install components that are already present in Windows 7.


ncb00008524 Description: Transfers to/from M-Series iVDR are not supported.
Workaround: Do not attempt to transfer to/from M-Series iVDR.
ncb00025753 Description: MXF streaming transfer to XDCAM recorder fails.

DE8762 Description: A channel is automatically configured as a 4K Recorder or 4K Player, even if it is currently in use. This occurs when you manually configure a first channel as a 4K Recorder or 4K Player and the second channel is automatically configured.
Workaround: As designed. Make sure channels are not in use before configuring any channel as a 4K Recorder or 4K Player channel.
DE10353 Description: On the Channel Configuration page, when a 4K Recorder (Top) or 4K Player (Top) is selected, channel ganging is used to join two channels together. A side effect is that any channels currently in the gang are removed. E.g., if C1 is configured as a 4K Recorder and C3 and/or C4 are in the gang, they will be removed from the gang.
Workaround: Click Cancel on the Channel Configuration page and the changes will not take effect.
DE10533 Description: 4K recording (individual quadrant) can get out of sync after video feed interruption.
Workaround: Provide a frame sync before the Summit input.

Dyno PA/Dyno

ncb00002810 Description: On a stand-alone K2 Summit/Solo configured for K2 Dyno PA, the V: drive is not available. This occurs if the K2 system is started without a network connection or otherwise used outside of the Dyno PA system.
Workaround: Remove the DLC configuration from the K2 Summit/Solo as instructed in Dyno PA documentation. Verify that the loopback adapter is at the top of the adapter order list. This is required for a stand-alone K2 system that is not part of a Dyno PA system.
ncb00076307 Description: K2 Dyno playlists with more than four audio tracks do not have the associated audio file, causing problems when exported. This occurs with K2 Dyno software version and K2 Summit software version, in which only four audio tracks are configured.
Workaround: Before exporting the playlist, configure the K2 Summit system to record eight audio channels.
DE8555 Description: Media storage fills rapidly each time a loop record is stopped and restarted with an append record. The amount of lost disk space may become significant after many stops and starts of append record.
Workaround: Start a record session and let it continue to run without stopping, and then restart with an append record.
