Sun Microsystems 6900 FC Link Error Status Report, To Check the FC Link Error Status Manually

FC Link Error Status Report

The virtualization engine’s host-side and device-side interfaces provide statistical data for the counts listed in TABLE 9-4.

TABLE 9-4Virtualization Engine Statistical Data

Count Type	Description
Link failure count	The number of times the virtualization engine’s frame manager
	detects a nonoperational state or other failure of N port
	initialization protocol.
Loss of	The number of times that the virtualization engine detects a loss in
synchronization	synchronization.
count
Loss of signal count	The number of times that the virtualization engine’s frame manager
	detects a loss of signal.
Primitive sequence	The number of times that the virtualization engine’s frame manager
protocol error	detects N port protocol errors.
Invalid transmission	The number of times that the virtualization engine’s 8-bit and 10-bit
word	decoder does not detect a valid 10-bit code.
Invalid cyclic	The number of times that the virtualization engine receives frames
redundancy code	with a defective CRC and a valid EOF. A valid EOF includes EOFn,
(CRC) count	EOFt, or EOFdti.

▼To Check the FC Link Error Status Manually

The Storage Automated Diagnostic Environment, which runs on the Storage Service Processor, monitors the FC link status of the virtualization engine. The virtualization engine must be power-cycled to reset the counters. Therefore, you should manually check the accumulation of errors during a fixed period of time. To check the status manually, follow these steps:

1.Use the svstat command to take a reading, as shown in CODE EXAMPLE 9-1. A status report for the host-side and device-side ports is displayed.

2.Within the next few minutes, take another reading.

The number of new errors that occurred within that time frame represents the number of link errors.
