Port Recovery

The following settings are available.

Setting

Description

 

 

Bad Device Recovery

When a port is already inserted into a zone, the port transforms F8 Failure

 

notifications into F7 Initialization notifications. When this occurs, the port

 

is bypassed and F7 Initialization notifications are allowed in the zone.

 

Once the initialization is complete, the Bad Zone Recovery Policy is

 

operational and prevents a port that continues to transmit F8 Failure

 

notifications from inserting into the zone.

 

Note: If this policy is disabled while the Bad Zone Recovery policy is

 

enabled, a zone that does go down will still allow the Bad Zone Recovery

 

policy to reset the zone and allow ports to be reinserted.

 

When enabled, this policy prevents devices that send F8 Failure

 

notifications from inserting into a zone. The ability to remove devices that

 

generate F8 Failure notifications automatically and instantaneously

 

guarantees continual system operation.

 

When disabled, this policy allows devices that send F8 Failure

 

notifications to insert into a zone and does not consider F8 Failure

 

notifications when determining whether to insert a device or not.

 

 

Clear on Stall

In situations where the switch is operating in switching mode, some

 

devices may fall into an operating mode where the device has opened a

 

target but has not released the connection to the target. When this policy

 

is enabled, the switch can detect this condition and automatically recover

 

when this situation arises.

 

 

Bypass on No Activity

The switch detects the amount of time a data stream has gone without

 

receiving a comma. The time setting is set to 100 (.001 seconds). When

 

this policy is enabled, the switch bypasses the disruptive port when the

 

threshold is exceeded.

 

 

Bypass on Ordered Set Error

Ordered Set (OS) errors are detected and counted for each individual

 

port. When this policy is enabled, a port is bypassed when its OS count

 

exceeds the threshold setting. The threshold setting is based on the

 

number of ordered set errors identified in 10 seconds.

 

Note: This threshold setting can be adjusted on the Web Manager’s

 

Advanced Functions Switch Thresholds page.

 

 

Bypass on CRC Error

Cyclic Redundancy Check (CRC) errors are detected and counted for

 

each individual port. When this policy is enabled, a port is bypassed when

 

its CRC count exceeds the threshold setting. The threshold setting is

 

based on the number of CRC errors identified in 10 seconds.

 

User intervention is required to return the port into the zone. Recovery

 

methods include replacing the defective component, cycling power to the

 

device on the port, removing and reinserting the bypassed port, or cycling

 

power to the switch.

 

Note: This threshold setting can be adjusted on the Web Manager’s

 

Advanced Functions Switch Thresholds page.
