Hello all,

we have a p690 IBM system running AIX 5.2 and we would like to attach it to a
storage partition of an SGI TP9500 via 2 2Gigabit FC connections (2 PCI-X FC
6239, type 5705 IBM adapters). The TP9500 is similar to a FASt 900.

Does anyone know of the necessary steps to accomplish this task? I've noticed
that the TP9500 requires the host port numbers (WWN) to be specified for the
partition that will be accessible by the IBM host. Does anyone know how to
obtain this information from the AIX side? How are failover paths for
FC storage specified in AIX 5.2?

Thanks a lot!

lsdev -Cc adapter (will show you your adapters)

lscfg -vpl fcsX (replace X with the various adapters)

the fastts normallly display a list of suitable WWNs. There are
various redbooks etc on the ibm site that will help you with this.
the main other component is the RDAC driver (bos.drivers.fcp.array.* I
think)

fget_config -A -v (I think that's right) should show you the
controllers and fastt it can see)

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

Adrian, thanks for the info. I was going over the various documentation pieces
at the IBM site and I found (among 100s of irelevant) the following to be
useful documentation:

FAStT
``Installation and Support Guide for AIX, HP-UX, and Solaris'',
Third Edition (2004-06-17), v. 05.42.03.00, ref. MIGR-55697
ftp://ftp.software.ibm.com/pc/pccbbs...f/kd602mst.pdf


FC Adapter Installation
``Fibre Channel Planning and Integration: User's Guide and Service
Information'', Fourth Edition (May 2002),
23329.pdf

Thanks for your reply!

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.

Michael
