Method of Rectifying Common Channel Faults

The process of creating a channel is as follows: On the service portal, issue a broadcast source file.

On the service portal, create a channel.

Create a channel in VS8000C.

VS8000C submits the result to MLSS.

CAUTION: Only one channel can be created for an SDP broadcast source file.

Terminal Displays WAIT CONFIG FROM FLR Repeatedly

Symptom: After the MSTU is started, the FAC or FAS process is

t t t d d th t i l di l “[ FAS POWERnot started and the terminal displays “[ FAS POWER ON ] WAIT CONFIG FROM FLR !!!" or “[ FAC POWER ON]WAIT CONFIG FROM FLR !!!" repeatedly.

2012/10/1

14

Terminal Displays WAIT CONFIG FROM FLR Repeatedly

Cause: The FAC or FAS process obtains configuration from the

FLR b t i t dFLR but no response is returned.

Solution: Check whether the FLR process runs properly, whether

the MSTU communicates with the OMP properly, and whether the FLR data is configured.

Disk Status Submitted by MSTU Is Abnormal

Symptom: After the MSTU is started, the FAC and FAS processes

l b t th b f di k b itt d b thrun properly but the number of disks submitted by the MSTU is insufficient or the disk status is abnormal.

Cause: A fault occurs in the disk, the disk is not mounted

properly, or data is configured incorrectly.

2012/10/1

Solution:1. Run the cat /proc/partitions command to check the disk.

2 If only the disk instead of the partitions is displayed by running the2. If only the disk instead of the partitions is displayed by running the cat /proc/partitions command, for example, /dev/sdb instead of /dev/sdb1 is displayed, it indicates that the disk is not partitioned.

3. If the disk is mounted properly but the disk information is not displayed in the HDDEV table in the probe, a problem occurs in data configuration. Therefore, configure the information about the disk such as COUPLEID correctly.


4. Run the cat /proc/mounts command to check whether the disk is mounted.

If the disk is not mounted the disk may not be formatted If the disk is not mounted, the disk may not be formatted correctly. Run the parted –s /dev/sdb1 print command to check whether the disk is partitioned.

If the file system type is not displayed, run the mkfs.xfs –f /dev/sdb1 command to format the disk.

Incorrect MDU External Network Configuration

Check whether the configured external network port is connected to a switch;

If a network cable is connected, check the port state: If the port flag is set to 0, the port is Down. If the port

flag is set to 1, the port is Up.

If the port state is Up, check whether the IP dd d t f th di taddress and route of the corresponding port are

configured in the database.

No Code Stream for Live Channels

Fault: After channels are created and a user demands a live

h l th STB i di tchannel, the STB receives no media stream.

Causes: An MDU receives the code streams of a live channel

through an external media port
