If the playlist appears grayed-out it means it does not match current channel settings. Check the video standard in the property of the source clip for each event in the playlist. Compare properties with those of a playlist that plays correctly. If properties are correct the playlist is corrupt. Delete and re-make the playlist.
Turn off the Remote mode. Or alternatively, enable local operations while being remote controlled.

Storage problems

Use the following sections if you suspect problems with your T2's storage system.

Media File System problems

Problem Possible Causes Corrective Actions
One or more clips do not play or record correctly.

Media disk problems

The media database is out of sync with the media files or there is a corrupt media file. Also see
"Checking the storage system" on page 88 for
causes related to certain usage patterns.
1. If the problem is only associated with a specific clip or clips, delete the problem clips.
2. If the problem persists, run the Maintenance Tools and check disk error. Refer to "Media
disk error checks" on page 31. If the problem
persists, run the database consistency check. Refer to "Checking the data consistency" on
page 34.
3. If the problem persists, check the RAID status. Refer to "Verifying, building, and rebuilding a
RAID volume" on page 44.
To check the SATA drives quickly, open My Computer from the Start menu, and check C:, D:, and V: drives. The C: and D: drives are in the SSD (for the system) above the 2.5 inch removable SSD bay. The V: drive is striped back of the touch screen LCD.
WARNING: Be sure to turn off the system and disconnect the power plug prior to checking the cabling and connections inside the T2, or removing/replacing any parts of the T2. Otherwise, electric shock or product failure may result.
Problem Possible Causes Corrective Actions
On startup the VGA startup sequence stalls at the black screen with a "Operating System not found" message.
There is a problem with SSD (for the system). This is the system boot disk.
Check the power cable and SATA cable of the SSD (for the system). If connections are OK, the SSD (for the system) is faulty. When the SSD (for the system) fails, the database, Config settings, and logs are lost. Replace the SSD (for the system). Refer to "SSD (for the
system) removal" on page 97.
If you want to use the media files of the data drive (V: drive) with the CommandCenter after replacement, copy the media files into the external storage device and then import them into V: drive. For detailed instructions, refer to the T2 User Manual.

Chapter 3 Troubleshooting Problems

Checking the storage system

The following section provides guideline for investigating problem areas related to the storage system. Use this section if you have problems with media input and/or output that are intermittent or seem to be related to certain usage patterns.
Problem Possible Causes Corrective Actions
Symptoms can include the video recording stop or black video at playout, frozen video, slow performance, or inconsistent media access.
The following causes can occur on their own or in combination to produce the problem:
• Disk oversubscription - This occurs when requests to the media disk exceed the disk’s bandwidth capabilities. This generally occur in extreme cases when a combination of high-bandwidth operations are taking place, such as JOG/shuttle, record/play on multiple channels.
• High CPU activity in Windows ­This occurs when activities on the Windows operating system over-tax the capabilities of the motherboard processor. This commonly happens when unsupported software has been installed that competes with the T2 applications. Virus scanners and screen savers can cause this type of problem, since they can start automatically and consume system resources.
• Disk faults - This occurs when a media disk is severely fragmented or has a bad blocks that interfere with some, but not all, media operations. For example, a particular clip can be written on a bad block, so the problem occurs only on that clip.
1. When you install the unsupported application software, uninstall them.
2. If the problem persists, try to re-create the problem. Identify all the interactions that affected the system and run all the same operations as when the error occurred. Investigate the functions that seem to push the system into the error state. If you determine that certain simultaneous operations cause the problem, re-order your workflow to avoid those situations. If you determine that the problem is only on certain clips, investigate disk faults.
