a| lsdev -Cc adapter (will show you your adapters)
a|
a| lscfg -vpl fcsX (replace X with the various adapters)
a|
a| the fastts normallly display a list of suitable WWNs. There are
a| various redbooks etc on the ibm site that will help you with this.
a| the main other component is the RDAC driver (bos.drivers.fcp.array.* I
a| think)
a|
a| fget_config -A -v (I think that's right) should show you the
a| controllers and fastt it can see)

a| Two things to be aware of:
a| a) ibm only supports certain AIX setups with fastt
a| b) certainly when ordering a fastt there is an "AIX attachement"
a| option - I imagine that this provides a license key to allow "AIX" to

Adrian,
we have connected the p690 to a partition of the TP9500 which was identified
by the WWPN of the two host adapters. We defined 2 LUNs and assigned then
under the p690 host.
On the AIX side, I have enabled/condigured the FC adapters and the FC SCSI
protocol drivers:
~% lscfg | egrep -i 'fc|fcp'
+ fcs1 U1.9-P2-I7/Q1 FC Adapter
* fscsi1 U1.9-P2-I7/Q1 FC SCSI I/O Controller Protocol Device
* fcnet1 U1.9-P2-I7/Q1 Fibre Channel Network Protocol Device
+ fcs0 U1.9-P1-I7/Q1 FC Adapter
* fscsi0 U1.9-P1-I7/Q1 FC SCSI I/O Controller Protocol Device
* fcnet0 U1.9-P1-I7/Q1 Fibre Channel Network Protocol Device
~% lsdev | egrep -i 'fc|fcp'
fc0 Defined 2v-08-02 Fibre Channel Network Interface
fc1 Defined 3e-08-02 Fibre Channel Network Interface
fcnet0 Available 2v-08-02 Fibre Channel Network Protocol Device
fcnet1 Available 3e-08-02 Fibre Channel Network Protocol Device
fcs0 Available 2v-08 FC Adapter
fcs1 Available 3e-08 FC Adapter
fscsi0 Available 2v-08-01 FC SCSI I/O Controller Protocol Device
fscsi1 Available 3e-08-01 FC SCSI I/O Controller Protocol Device
I asked AIX to rediscover the h/w and load device drivers. I did this manually
(cfgmgr -v) and through SMIT.
cfmgr -v reports:
Method error (/usr/lib/methods/cfgefscsi -l fscsi1 ):
0514-061 Cannot find a child device.
Method error (/usr/lib/methods/cfgefscsi -l fscsi0 ):
0514-061 Cannot find a child device.
The problem is that the LUNs do not appear as new hdisks after the cfgmgr
command. There are no [r]dac devices showing up.
Also:
~% lsattr -D -l fscsi0
attach none How this adapter is CONNECTED False
dyntrk no Dynamic Tracking of FC Devices True
fc_err_recov delayed_fail FC Fabric Event Error RECOVERY Policy True
scsi_id Adapter SCSI ID False
sw_fc_class 3 FC Class for Fabric True
~% lsattr -D -l fscsi1
attach none How this adapter is CONNECTED False
dyntrk no Dynamic Tracking of FC Devices True
fc_err_recov delayed_fail FC Fabric Event Error RECOVERY Policy True
scsi_id Adapter SCSI ID False
sw_fc_class 3 FC Class for Fabric True
Any idea of what may be going wrong? Any hint on connecting AIX/p690 and
TP9500 is going to be appreciated.
