2GB FC Adapter in p55A

[ogniemi]

where to fidnd a guide for the adapter (described all its states, LED blinkging/lighting)

Adapter is cabled by SAN guys, they double checked it and when I run:

rmdev -Rl fcs0
cfgmgr -l fcs0
lsattr -El fscsi0 -l attach

I don't see "switch" but "none".


thx in advance.

Did you check SAN Switch Zoning?

I have found the guide on site:

http://publib.boulder.ibm.com/infoc...ibm.pseries.doc/hardware_docs/pciadapters.htm

thx.

Try this:

rmdev -Rdl fscsi0
rmdev -dl fcnet0
rmdev -l fcs0
cfgmgr -l fcs0

This way, the FC adapter re-negociates an FC fabric logon.

hello P5wizard,

I had already done something similiar but it didn't helped:

# lsslot -c slot|grep fcs0
U787B.001.DNWFFM5-P1-C4 Logical I/O Slot pci4 fcs0
# rmdev -dl pci4 -R
fcnet0 deleted
fscsi0 deleted
fcs0 deleted
pci4 deleted
# cfgmgr
Method error (/usr/lib/methods/cfgefscsi -l fscsi0 ):
0514-061 Cannot find a child device.
# lsattr -El fscsi0 -a attach
attach none How this adapter is CONNECTED False

the second FC is connected ok:
# lsattr -El fscsi1 -a attach
attach switch How this adapter is CONNECTED False
#

thx anyway,
I will ask my SAN team to check cables once more.

That means the FC cable is probably faulty (or it is not crossed? receive/transmit need to corss over in the FC cable)

Perhaps the switch port is not enabled, or the SFP module is bad.

Bottom line is: SAN guys need to double/triple check...

What you can do (to make sure it isn't the adapter that is faulty): unplug SAN cable from adapter, plug in a jumper plug (comes with the adapter) and reconfigure as above - connection should come up as arbitrated loop. If not, then your adapter is at fault or maybe not seated properly in the PCI slot? But that should manifest itself in the error log also.)

thx.

there are no errors in errorlog reported.
I am going to switch cables between FC adapters and then will check again the status both of them with swapped cables.
best regards,.
