Disk modules
There are 2 slots for disk modules in the K2 Solo Media Server. The slots are located
behind the front be zel as sembly in the front o f t he c hassis. Each slot can con tai n one
disk module, and each module contains one hard drive. A K2 Solo Media Server
contains 2 disk modules. Disk modules plug into the drive cable assembly.
Data is written or “str iped” acr oss the disks in a cont inuous fa shion, whic h makes the
disks a “stripe group”. This stripe group appears as the V: drive to the Windows
operating system. The V: drive stores media. It also stores media file system,
database, and configuration information.
Disks are configured as RAID 0, so you can not remove and replace a disk module
while the K2 Solo Media Server is operational. If a disk fail s, you lose al l media.

beeps. Otherwise, if there are no errors present, the K2 Solo Media Server does not
emit any audible beeps.
When an error occurs during Power On Self Test (POST), the BIOS displays a POST
code that describes the problem. The BIOS might also issue one or more beeps to
signal the problem. This indicates a serious error and it is likely that the carrier module
must be replaced. Contact Grass Valley Support.

About the write filter
The K2 Solo Media Server has a file-base d write filter , which is a feature of the
Windows embedded operating system. With the write filter enabled, files can be
created, modified, an d de leted, but these cha nges a re hel d i n a memory cache. When
the K2 Solo Media Server restarts, these changes are lost and the K 2 Solo Media
Server returns to its original state. This protects the K2 Solo Media Serve r from
changes and increases on-air reliability. For any system configuration change the
write filter must be dis abled otherwise chang es are lost at the next restart.
Some directories, such as C:\logs, C:\Profile\config, and C:\Profile\ChannelSuites,
are excluded from write filter protection, so that channel configuration and logs are
saved. Do not attempt to alt er this list of excluded di rectories. If you suspe ct that write
filter configuration has been alter ed, use the recovery i ma ge p rocess to restore to the
default configuration.
To enable the write filter, the K2 Solo Media Server must be restarted. Likewise, to
disable the write filter, the K2 Solo Media Server must be restarted. You can enable/
disable the write filter remotely using the SiteConfig lock/unlock feature on one K2
Solo Media Server a t a t ime or on a group o f K2 Solo Med ia Server s all a t once. You
can also enable/disab le the write filter from a local K2 Solo Media Server.

Checking pre-installed software
Software is pre-installed on K2 products when you receive them from the factory.
This load of pre-installed software is referred to as the “golden drive”. The following
list is an example of the software pre-installed. Check K2 Release Notes for the most
up-to-date list with version information.
If you suspect that pre-installed so ftware is not c orrect, use the recovery process to
re-load the software. Do not attempt to un-install, install, or repair pre-installed
software without guidance from your Grass Valley Support representative.

• “Creating a recovery image” on page 63
• “Restoring from a recovery image” on page 65
• “Using CompactFlash boot media for system restore” on page 66
About the recovery image process
An image of t he K2 Solo Media Server system drive is provided with the product
package. You can restore the K2 Solo Media Ser ver fr om this imag e. This si mplifi es
the process of rebuilding a system in a disaster recovery scenario.
NOTE: This process is not intended as a means to backup and restore media.
When you receive your K2 Solo Media Server new from the factory, you receive a
system-specific image for that particular K2 Solo Media Server. This factory image
is stored on a bootable USB Recover y Flash Drive. Also on the Rec overy Flash Drive
is the Acronis True Imag e software necessa ry to create and rest ore an image. You can
find the Recovery Flash Drive in a holder behind the front bezel.
62 K2 Solo Media Server Service Manual 09 April 2010
Page 63
Creating a recovery image
After your K2 Solo Media Server is i nstalled, conf igured, and r unning in your system
environment, you should create a new recovery image to capture settings changed
from default. This “first birthday” image is the baseline recovery image for the K2
Solo Media Server in its life in your facility. There is enough space on the Recovery
Flash Drive to store the first birthday image along with the factory image.
You should likewise create a new recovery image after com pleting any process that
changes system software or data, such as a software upgrade. In this way you retain
the ability to restore your K2 Solo Media Server to a recent “last known good” state.
You can also use the recovery image process on the control point PC.
NOTE: The recovery image process is an “off-line” process. Do not attempt this
process while media access is underway.
The recovery image process that you should follow is summarized in the following
steps.
At the K2 Solo Media Server first birthday…
1. Boot from the Recovery Flash Drive.
2. Create a recovery image for the K2 Solo Media Server.
3. Create a recovery image for the Control Point PC.
At milestones, such as software upgrades…
1. Boot from the Recovery Flash Drive.
2. Create a recovery image for the K2 Solo Media Server.
If you need to restore the K2 Solo Media Server…
1. Boot from the Recovery Flash Drive.
2. Read the image from the Recovery Flash Drive or from the loca tion that you store d
the image.
If you need to restore the Control Point PC…
1. Boot from the Recovery Flash drive.
2. Read the image from the location that you stored the image.
Use the following proc edures to implement the recovery image process as necessary.
Creating a recovery image
Before creating a recovery image , determine t he storage lo cation for the image. If yo u
have not already stored an image on the Recovery Flash Drive, there is sufficient
space available a nd you can store the i mage on t he Recover y Flash Drive. Otherwise,
use a network connected drive or another connected USB drive.
1. Make sure that media access is stopped and that the K2 Solo Media Server on
which you are working is not being used.
2. If you have not already done so, connect keyboa rd, mon it or, a nd mouse to the K2

Chapter 4 Troubleshooting problems
Step 1: Check configurations
Many times what appears to be a K2 Solo Media Server fault is actually an easy-to-fix
configuration problem. Check settings in Configuration Manager and verify that the
system is configur ed as you e xpect. Refe r to th e K2 App Center Us er Manual and t he
K2 System Guide.
Step 2: Check connections and external equipment
Loose or improperly connected cables are the mo st li kel y so urc e of problems for the
system. A quick check of all the cable connections can easily solve these problems.
Refer to the K2 System Guide for help with making connections. Refer to the
troubleshooting top ic “Checking external equipment” on page 75 if you suspect a
failure in a device connected to the K2 Solo Media Server.
Step 3: Check system status messages
While the K2 Solo Media Server is in operation, some problems are detected and
reported in system status messages. To view system status messages, in AppCenter
Help | System Status. Also refer to “Viewing AppCenter system status
select
messages” on page 41.
When connec ting to a K2 Solo Media Serv er from a cont rol point PC using remote
AppCenter, if there is an AppCenter system startup error, the error is reported during
the connection attempt.
If the system status message indica te s a problem, refer t o the related troubles hoot ing
topic later in this chapter.
NOTE: Do not use the MegaRAID uti lity o n a K2 Solo Med ia Server. Thi s utili ty is
for use by qualified Grass Valley Service personnel only. When this utility is opened
it scans the SCSI bus and interferes with record and play operations.
Step 4: Identify problems using the startup
sequence
The startup sequence is your primary tool for identifying a K2 Solo Media Server
fault. As the different levels of the K2 Solo Media Server system become operational
in the startup process, the primary components of the system are checked. You can
identify most problems by evaluating the messages and other indicators that occur
during the startup sequence.
NOTE: This procedure assumes that the K2 Solo Media Server is not in Storage
Utility’s “offline” mode.
To identify problems using the startup sequence, do the following:
1. Connect mouse, keyboard, and monito r. You must obs erve the VGA s creen and be
able to intera ct with t he sys tem via ke yboard and mouse to fully i dentify problems.
2. Restart the K2 Solo Media Server. If you have pr oblems, refer to “Shutdown/restart
problems” on page 74 .

Checking the storage system
The following section provides guideline for investigating problem areas related to

output that are intermit tent or seem to be related to certain usage patterns.
Problem Possible Causes Corrective Actions
Symptoms can include
black video recorded or at
playout, frozen video, slow
performance, or
inconsistent media access.
These symptoms can be
accompanied by
StatusPane messages
regarding disk problems or
overrun/underrun
conditions for encoders,
decoders, or tim eco de .
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 combinati on
of high-bandwidth operations are
taking place, such as jog/shuttle,
record/play on multiple c han ne ls, o r
streaming multiple clips.
High CPU activity in Windows —
This occurs when activities on the
Windows opera tin g s y s tem o ve r -ta x
the capabilities of the CPU. This
commonly happens when
unsupported software has been
installed that competes with K2 Solo
Media Server applications. Virus
scanners and screen savers can cause
this type of problem, since they can
start automatically and consume
system resources.
Encoder overrun — This occurs
when an encoder is flooded with
more data than it can process within
its real-time requirements for
recording.
Decoder underrun — This occurs
when a decoder is starved for data
and cannot deliver enough to satisfy
real-time requirements for playout.
Disk faults — This occurs when a
media disk is se verely fr agmented or
has a bad blocks that inte rf er e 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.
Checking the storage system
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. Record/play/
stream the same clips.
Investigate the functions that
seem to push the system into the
error state. If you determine that
certain simultaneous operations
cause the p roble m, re-or der yo ur
workflow to avoid those
situations. If you determine that
the problem is only on certain
clips, investigate disk faults.
