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.
