Storage problems
Checking the storage system
Use this section if you have problems with video input and/or output that are intermittent or seem
to be related to certain usage patterns.
"Degraded" or "Failed" appears in "Status"
on the BIOS screen during T2 startup.
The T2 starts up in the maintenance mode even
when starting up in the CommandCenter mode.
RAID system has some
problem.
Delete and rebuild the RAID volume.
If the problem persists, replace the
faulty disk. Refer to
RAID volume maintenance" on
page 36
Problem
Possible Causes
Corrective Actions
Symptoms can include the
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 drive
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 drive 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. If unsupported software installed,
uninstall them.
2. If the problem persists, reproduce 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, change the workflow to avoid
those situations. If you determine that
the problem is only on certain clips,
investigate disk faults.
3. Refer to
to perform
defragmentation of the media drive. If
the problem is not solved after
defragmentation, refer to
RAID volume maintenance" on page 36
to rebuild the RAID and format the disk.
