Installation guide

The jfca driver for these HBAs is prone to race conditions when certain operations are being
run, and thus causes the errors. The operations are the following:
■
Link reset
■
Loop reset
■
Switch reset
■
Repeated link failures
Error messages similar to the following examples might be displayed:
■
I/O failure messages
jfca: [ID 277337 kern.info] jfca4: Sequencer-detected error. Recover
immediately.

System panic message
panic[cpu1]/thread=2a100497cc0:
BAD TRAP: type=31 rp=2a1004978d0 addr=a8 mmu_fsr=0 occurred in module
"jfca" due to a NULL pointer dereference
Workaround: Do not connect tape devices to either the SG-PCI1FC-JF2 or SG-PCI2FC-JF2
HBA.
Contention Exists Between Certain DevicesThat Share
the Same Bus (6196994)
A bus contention occurs if Quad Fast-Ethernet (QFE) cards share the same bus with any of the
following adapters:
■
Sun GigaSwift adapter
■
Sun Dual Gigabit Ethernet and Dual SCSI/P adapter
■
Sun Quad Gigaswift Ethernet adapter
The innite-burst parameter of the ce driver that is used by these adapters is enabled by default.
Consequently, little or no bus time is available for the QFE ports that share the same bus.
Workaround: Do not place QFE cards on the same bus as the network adapters in the list.
