K2 Summit

KT-9080	Description:	Upgrading with 9.7.0.x installer results in a failed upgrade.
	Workaround:	Use SiteConfig to upgrade K2 Summit software for the 9.7.0.2427 build and later. This is the only supported K2 Summit upgrade process for STRATUS sites. This process forces an uninstall then install type of operation with a K2 Summit system, requiring two reboots, one after the uninstall and one after the install. If a "manual" installation process is taking place for a non-STRATUS system without using SiteConfig, etc. then manually perform an uninstall of existing K2 Summit software before installing K2 Summit software for the 9.7.0.2427 build and later.
KT-9078	Description	STRATUS K2 Configuration Service fails to start - install .NET 4.6
	Workaround:	None.
KT-9057	Description:	File transfers fail during failover.
	Workaround:	File transfers are not supported during failover. This is due to the fact that file transfers require building a list of transfers, in memory, and when failover occurs, that memory becomes unavailable (e.g., FSM power down during failover) so there's no way to continue or complete file transfers.
KT-9025	Description:	Error messages when gang recording clips with only one video track.
	Workaround:	When gang recording clips with only one video track (“Record video from all channels to same clip” is unchecked), when the recording is first started, error messages of the form “could not find track #1 of type 11 in movie 'V:/default/Clip_15'” can be observed in the K2 Summit log. These error messages occur only as a single set of events when recording is started. These error messages are benign and can be disregarded. A work-around is to leave “Record video from all channels to same clip” checked.
KT-8727	Description:	4K Monitoring Output available only via SDI connector
	Workaround:	With the 9.7 release, 4K Quadrant Division Recorder and 4K Quadrant Division Player modes of operation are now supported via SMPTE 2022-6 and the 10GigE connectors. The 4K Monitor Output feature described in the topic library is only supported via the SDI IN3 connector, it is not available via SMPTE 2022-6 and the 10GigE connectors.
KT-9363	Description:	Error messages with continuous record mode when used with DNxHD. Known issue version: K2 Summit 9.2, 9.3, 9.4, 9.5, 9.6, 9.7. Error messages are observed at three minute intervals with 1-hour continuous record mode and with the DNxHD encoder is selected for the Compression Format.
	Workaround:	None

Recommended maintenance schedule for K2 products

As with any tool regular maintenance and attention to the K2 clients and servers will help prevent problems and detect issues before they interfere with operations. Be sure to check the operation of K2 clients and servers on a regular basis. Products such as NetCentral and GV Guardian are key components to keep systems running well and alerting when problems arise.

NOTE: Those with the "1 year+" notation have run under normal operation well beyond 1 year in service. We still recommend a preemptive reboot on a regular schedule when such maintenance is planned. This helps ensure the system does not go down for preventable situations when it is not planned.

Grass Valley recommends a regular reboot for clients and servers to avoid situations that will unexpectedly take down a system. Here is the recommended schedule:

K2 Clients (3.3 and earlier software)	6 months
K2 Servers (3.3 and earlier software)	1 year
K2 Summit (7.3 and earlier software)	6 months
K2 Summit (7.4 to 8.1 software)	1 year
K2 Server (Windows Server 2003)	1 year
K2 Summit/Summit3G (9.0 and later software)	1 year+
K2 Server (Windows Server 2008 R2)	1 year+
K2 Server (Windows Server 2012 R2)	1 year+

K2Config/Site Config and Windows Server 2012

Known Issues in Previous Releases

KT-8065	Description:	When installing SharedBinaries on a Windows 2012 Server, it think it's upgrading the QLogic driver.
	Workaround:	De-select QLogic driver upgrade in SiteConfig.
KT-8042	Description	SiteConfig stuck during upgrade of Summit from 9.4 to 9.5
	Workaround	Reboot Summit, uninstall 9.4 manually, then install 9.5 manually.
KT-8045	Description	Problem with SiteConfig upgrading SAN from 9.3/9.4 to 9.5.
	Workaround	Reboot Summit, uninstall 9.4 manually, then install 9.5 manually.

K2 Central

KT-8036	Description:	Document command line for loading firmware to multiple drives
	Workaround:	It is recommended to have all drives in a K2Central server at the same version of firmware. Drive firmware can be updated one drive at a time using StorageUtil. Another way is to flash the firmware for all drives in a system with one command. Procedure: Open a command shell or power shell window with administrator access. Execute the following command using the name of the drive firmware file to flash to all drives. cd C:\Program Files (x86)\MegaRAID Storage Manager StorCLI64.exe /c0 /sall download src=<file> Example: StorCLI64.exe /c0 /sall download src=HITACHI_7K6000_A519.bin Firmware will be updated to each drive one at a time. Ignore timeouts and let the process run to completion. A set of 24 drives takes about 15 minutes to update.
KT-2597	Description	FTP transfers are not always shown in the Summit's transfer monitor.
	Workaround	None.
KT-2123	Description	Update K2-Central installer to install 64-bit components
	Workaround	None.

AppCenter

KT-9220	Description:	When using 3x MultiCam Recording with 16 audio tracks and the independent ancillary data enabled, the recording fails.
	Workaround:	Reduce either the number of Multi-Cams, Audio tracks or using the same ancilliary data for each input.

Other

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 configuration returns to default after an upgrade. If licenses are removed from Summit before a software upgrade the channel channel configuration settings may be reset to default. Please leave existing licenses in place when upgrading from 9.4 to 9.5 or else the channel configuration will reset to the factory default settings.
	Workaround:	None.
KT-2163	Description:	Led's behave differently for a disabled drive between old (LSI) and new (AIC) raid controllers
	Workaround:	None.
KT-2490	Description:	Bad E-to-E SD media streams output with Multi-Cam Recorder
	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.

K2Config/Site Config and Windows Server 2012

Known Issues in Previous Releases

When the firewall is enabled, SiteConfig can't install software on Server; K2Config can't connect to the server and configure it.
	Workaround:	Then restart SiteConfig/K2Config. Note that the base image has all firewall disabled.

AppCenter

ncb00003440	Description:	Bins nested more than nine levels deep are not supported. Database errors can occur.
ncb00003440	Workaround:	Constrain bins to nine levels deep or less. This includes the top-most bin.
ncb00003457	Description:	Closed captioning and/or ancillary data not present in the last few seconds of a growing clip's playout. This occurs when playing out a clip that is being recorded, and the recording stops.
ncb00003457	Workaround:	Stop playout of growing clip before stopping recording. In any case the closed captioning and/or ancillary data is full-length in the recorded clip and present in subsequent playout.
ncb00039062	Description:	The system clock may not update when the TimeOfDay source is changed.
ncb00039062	Workaround:	If this happens reboot after the TimeOfDay source change.
ncb00003919	Description:	When reconfiguring channel security settings on Configuration Manager Security tab, AppCenter does not allow username/password fields to be blank.
ncb00003919	Workaround:	Enter username/password for a valid user account. Once configured, the fields require valid information.
ncb00004073	Description:	Recorded video is one frame late relative to timecode. This occurs if you record using Time-of-day timecode and the source is from channel four's LTC input.
ncb00004073	Workaround:	Connect the house LTC input to channel 1 and use it as the Time-of-day source.
ncb00002648	Description:	AppCenter does not allow a clip to be deleted if the clip is associated with a playlist, program, or subclip.
ncb00002648	Workaround:	First use the "Consolidate Media" feature on the clip, then delete the clip.
ncb00002781	Description:	Video faults continue to occur if Super Slo-Mo inputs lose and then regain phase alignment while recording is underway.
ncb00002781	Workaround:	If inputs lose phase alignment, first restore phase alignment and then stop and restart the recording.
ncb00035282	Description:	On K2 Summit Transmission models, only two audio tracks can be created for new Playlist.
ncb00035282	Workaround:	Switch the channel to a Player/Recorder, set the number of audio channels, then create the Playlist.
ncb00038746	Description:	Audio errors occur when playing a clip while importing from a USB device.
ncb00038746	Workaround:	Copy first, then play. Playback while importing from USB not supported.
ncb00075492	Description:	After a failover event occurs on the K2 SAN, there are multiple decoder errors when playing an Avid DNxHD, AVC-Intra, or DVCPROHD clip that was recorded at the time of the failover.
ncb00075492	Workaround:	Delete clips that exhibit these errors and re-record them.
DE8566	Description:	If a channel is running as a Playlist when it is configured to be a 4K Player, 4K Recorder, 3D/Video+Key Player or 3D/Video+Key Recorder then it will not play or record correctly.

DE6779	Workaround:	Contact Grass Valley Support.
DE6940	Description:	An iSCSI-attached K2 Summit SAN client system fails to play or record two channels of 1080p when the other two channels are doing a continuous record of 1080p.
DE6940	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.
DE6954	Workaround:	None. Thumbnails are no longer updated as records continue in K2 TimeDelay.
DE7330	Description:	A long continuous recorded clip might not delete successfully. The clip is deleted from the media file system, yet the clip is still displayed in AppCenter.
DE7330	Workaround:	Use the Storage Utility Clean Unreferenced Movies feature. This removes the display of the clip from AppCenter.
DE8525 ncb00075905	Description:	FTP transfers fail to/from a K2 Media Server with role of FTP server. This occurs on first start-up after re-image.
DE8525 ncb00075905	Workaround:	Reboot the K2 Media Server, and restart the Grass Valley FTP Dameon service.

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.
DE11433	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.
ncb00041093	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.
ncb00061128	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.

Installation

ncb00003885	Description:	If uninstalling or installing K2 client software while applications or connections to AppService are open, the installation program becomes unresponsive.
ncb00003885	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...".
ncb00040814	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.

Compatibility

ncb00008524	Description:	Transfers to/from M-Series iVDR are not supported.
ncb00008524	Workaround:	Do not attempt to transfer to/from M-Series iVDR.
ncb00025753	Description:	MXF streaming transfer to XDCAM recorder fails.
ncb00025753	Workaround:	None. Some Sony deck models do not comply with the MXF standard.

4K



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.
DE10353	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.
DE10533	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.
ncb00002810	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 2.0.4.143 and K2 Summit software version 8.1.11.1810, in which only four audio tracks are configured.
ncb00076307	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.
DE8555	Workaround:	Start a record session and let it continue to run without stopping, and then restart with an append record.
