ServerNet Resources: Monitoring and Recovery

Monitoring the ServerNet Fabrics Using SCF

Normal ServerNet Fabric States

Normal states for a path on the ServerNet fabrics can be one of:

UP

The path from the processor in the FROM row to the processor in the TO column is up. The status for all ServerNet connections between existing processors in a system should be UP.

<-DOWN (for an entire row)

The processor in the FROM row is down or nonexistent. If the processor in the FROM row does not exist on your system, this status is normal. Otherwise, refer to Identifying ServerNet Fabric Problems on page 7-7.

UNA (unavailable)

The processor in the TO column is down or nonexistent. Therefore, the path from the processor in the FROM row to the processor in the TO column is down. If the processor in the TO column does not exist on your system, this status is normal. Otherwise, refer to Identifying ServerNet Fabric Problems on page 7-7.

Identifying ServerNet Fabric Problems

Depending on how your system is configured, these states for a path on the ServerNet fabrics might indicate a problem:

DIS (disabled)

The ServerNet fabric is down at the TO location. As a result, the path from the processor in the FROM row to the processor in the TO column is down for receiving; that is, the processor in the TO column cannot receive from any other processor or from I/O devices. DIS overrides both UP and DN.

DN (down)

The path from the processor in the FROM row to the processor in the TO column is down because the path is failing. The processor in the FROM row cannot send to the processor in the TO column.

<- DOWN (for an entire row)

The processor in the FROM row is down or nonexistent. For a processor that does exist on your system, this status is abnormal.

ERROR nnn (for an entire row)

The processor in the FROM row unexpectedly returned a file-system error to that ServerNet fabric.

UNA (unavailable)

The path from the processor in the FROM row to the processor in the TO column is down because the processor in the TO column is down. For a processor that does exist on your system, this status is abnormal. UNA overrides all other states.
