Blade troubleshooting tips
This chapter refers to the following specific types of blades inserted into either the Brocade DCX,
DCX 8510 family, and DCX-4S enterprise-class platforms:
•
FC blades or port blades contain only Fibre Channel ports: Brocade FC8-16/32/48/64.
•
AP blades contain extra processors and some have specialized ports: Brocade FCOE10-24 and
FX8-24.
•
CP blades have a control processor (CP) used to control the entire switch; they can be inserted
only into slots 6 and 7 on the Brocade DCX and DCX 8510-8, and slots 4 and 5 on the Brocade
DCX-4S and 8510-4.
•
CR8 and CR4S-8 core blades provide ICL functionality between two Brocade DCX Backbones.
CR8 blades can be inserted only into slots 5 and 8 on the Brocade DCX. CR4S-8 blades can be
inserted only into slots 3 and 6 on the Brocade DCX-4S.
•
CR16-8 and CR16-4 core blades provide ICL functionality between two Brocade DCX 8510
Backbones. CR16-8 blades can be inserted only into slots 5 and 8 on the Brocade DCX
8510-8. CR16-4 blades can be inserted only into slots 3 and 6 on the Brocade DCX 8510-4.
Typically, issues detected during firmware download to AP blades do not require recovery actions
on your part.
If you experience frequent failovers between CPs that have different versions of firmware, then you
may notice multiple blade firmware downloads and a longer startup time.
Symptom Relocation of internal image times out on CR8 core blade.
Probable cause and recommended action
This can be caused by issues in the co-CPU. If this happens, the firmware download process
synchronizes the partitions in the main-CPU and co-CPU by starting a firmware commit operation.
Wait at least 15 minutes for the commit operation to complete, issue the firmwareShow command
to verify the partitions are synchronized, and reissue the firmwareDownload command. If the
problem persists, you must contact the switch service provider.
