Change L-Ports to F-Ports

[Jason Bischoff]

I have a VA7100, VA7400, 2/20 LTO drive with Fibre Card, and 4 servers (WIN2K) in a SAN. They are all connected to a Brocade (HP OEM) 2800 16 port switch.

The VA7100 and VA7400 are showing correctly as F-Ports, but all the other devices are showing as L-Ports.

My problem is that everytime a server is rebooted, or the tape library is rebooted, (I think it causes something called a LIP) it causes drives to disconnect.

How can I remedy this? Is it a matter of changing the port types to fabric ports (F-Port)?

It depends...

You may have to adjust the HBAs in the servers to get them to try Fabric mode.

Also, the tape drive Fibre Card should need to be put into Fabric mode.

If Quickloop mode is enabled on the switch, turning it off should help you along the way.

Good luck,

Vince

Jason,
which FC cards are installed in servers? Configuration depends on it.
In addition, please remember that alternate paths for library/tapes ARE NOT supported. It means that you should not see library more than once in device manager. If you use one brocade switch, I believe it's a case. Please use zoning to force only one HBA of each server to acces library (fortunately all HP brocade switches have zoning licence already installed!).
In your SAN everything should be in fabric. Please check supportshow brocade output (and zip and attach to your next reply)

There 4 HBa's -- 2 Compaq and 2 HP

The Compaq HBA's are 64bit/66MHz storageworks cards, and the HP HBA's are Agilent HHBA 510x PCI cards.

Everthing is currently setup in 1 zone.

1. If you use Autopath remember: it only supports one type of FC cards within server. So you should have either all CPQ (actually Emulex ones) or all HP within server;
2. D8602 driver should be upgraded to AFC9XXX.SYS available at http://h20004.www2.hp.com/soar_rnotes/bsdmatrix/matrix213991en_US.html (read readme carefully before upgrading);
3. CPQ drivers at http://h18006.www1.hp.com/products/storageworks/softwaredrivers/fca2101/index.html (or search for suitable for your installed card);
4. to setup D8602 in fabric use its n_dgto.reg file (included in driver's package);
5. to setup Emulex/CPQ board in fabric you can refer to http://www.emulex.com/ts/docfc/w2kmini/5481a4/tocconfigure.htm : "EmulexOption" should have bit 0x1000 set; ResetTPRLO=0; Topology=2 (fabric);
6. Galactica library should be set up to work in fabric also. Check it with its control panel.
Remember: all registry modifications/driver installations/upgrade will require reboot
Good luck!
