A6795A - how to set topology to FABRIC

[Ross Minkov]

I have an rp5470 server running HP-UX 11i (B.11.11) with 2 x fibre channel adapters (A6795A) - /dev/td0 & /dev/td1. How can I check/set the topology for them. I want to set them to FABRIC.

TIA,
Ross

I didn't have to set anything. The card/driver figured it out once it connected to the switch. We have a Connectrix switch connected to an EMC 8430. All Fabric.

perform an 'fcmsutil /dev/td0' (or td1) for the current status. The actual login should be set at the fibre switch / hub when it performs an PLOGI or FLOGI, depending on the status of the port.

What devices are these cards connected to?

These card usually auto-sense the other end of the port, so if your switch (or whatever else is there) is set to Fabric, your card should sense it. fcmsutil will show you the settings.

[Geoff Wild]

You set the topology on your switches - not the HBA's...

As others have said, to check - use the fcmsutil.

Example:

# fcmsutil /dev/td0

Vendor ID is = 0x00103c
Device ID is = 0x001029
XL2 Chip Revision No is = 2.2
PCI Sub-system Vendor ID is = 0x00103c
PCI Sub-system ID is = 0x00128c
Topology = PTTOPT_FABRIC
Link Speed = 1Gb
Local N_Port_id is = 0x031b00
N_Port Node World Wide Name = 0x50060b000010d39f
N_Port Port World Wide Name = 0x50060b000010d39e
Driver state = ONLINE
Hardware Path is = 0/0/10/0/0
Number of Assisted IOs = 8909524
Number of Active Login Sessions = 2
Dino Present on Card = NO
Maximum Frame Size = 960
Driver Version = @(#) PATCH_11.11: libtd.a : Jun 28 2002, 11:08:35, PHSS_26799

Set the topology on the switch and the card will auto sense the topology .

Once the card is connected to the switch run this command to check what topology its using :
#/opt/fcms/bin/fcmsutil /dev/td0

The fabric topology comes up as PTTOPT_FABRIC .
