Working With Columns
InitTag Column
The
InitTag
• XPT Init Tag (SAS/SATA): Generated by Expert, SAS Init Tag containing target information
from the first frame propagated to all the frames of the conversation.
• Init Tag: SAS Init Tag in the Open Address Frame (the first frame of the conversation).
Tag Column
The Tag
• OX_Id (FC)
• InitTaskTag (iSCSI)
• Task Tag (SSP)
• XPT QueueTag (SATA): Generated by Expert, Queue Tag of the first frame of a particular
command added to all events that are associated with that command.
• Queue Tag (SATA): Queue Tag of the first frame of a particular command.
• 8-bit TLP Tag (PCIe)
• 32-bit NVMe exchange ID for packets with an NVMe payload. That exchange ID is composed
of the 16-bit SQID (Submission Queue ID) followed by the 16-bit CID (Command ID). You
can filter on that tag to isolate all the packets of one NVMe exchange.
Errors/Warnings Column
The Errors/Warnings
primitive. The details of all the errors can be viewed in the inspector dialog. TraceView detects
frame embedded CRC and checksum errors. The
detected by TraceView, as well as the hardware detected errors.
Stateful Errors
TraceView can store between 0 and 3 stateful errors per event. If Expert is unable to report all
stateful errors, the text "More information in Expert" will appear in the Errors/Warnings column of
TraceView's main window.
Multiplexing Alignment Errors
For multiplexing alignment errors, the MUX-1 and MUX-0 primitives will be marked with an
alignment error if the hardware had to re-sync the multiplexing and redirect a MUX primitive to
the correct logical link. The hardware will always direct MUX primitives to the correct lane, thus
re-syncing the multiplexing. You should never see a MUX-1primitive on logical link 0, and never
see a MUX-0 primitive on logical link 1.
