MSA 2000fc direct connect

> via FC-AL or Private Loop.

Private Loop or Public Loop are both using Fibre Channel Arbitrated Loop (FC_AL) protocol. The first one uses 8-bit addresses. The second one uses 24-bit addresses with a Fabric Switch (FL_Port) as part of the loop.

Thanks for answers, but i need to know what about multipathin, did it work in direct connect? and how direct-conect works in real life, what about stability of this solution?

Hi Max

Multipath installation is the same, and has an impact on event handling, request handling and device initialization.

Software can be download from:

http://www.hp.com/go/msa

Download the HP msa2000 mpio dsm package under software and drivers.

The drivers are installed under:
C;\program files\Hewlett-Packard\HP MPIO DSM\msa2000

dsmcli is the utility used to manage mpio

Hi,

I'd like to ask a question which may not be directly related to this thread but I couldn't find any other.

My problem is that I can't run any command in dsmcli. All of the commands fail with "command failed!" message.

My machine is
- DL380 G5
- DSM MPIO version is 2.2.0.22.
- Win2003 32-bits.
- Emulex HBAs

Best Regards,

Bora

After reading this and looking at the documentation I am confused. I have what I believe are a couple of straightforward questions:

Environment.

1 x DL580 Server with 2 single port HBA's.
1 x HP MSA2000fc with dual controllers.
VMWare ESX 3.5 runing on server
Currently cabled HBA0 to CTLA Port 0, HBA1 to CTLB Port 0.

One Virtual Disk created
Two LUNs created
Each LUN presented to ALL hosts

ESX see's both LUNs on HBA0 but nothing on HBA1 (during normal operation - no failover testing performed to-date)


Questions:

1. I currently do not have PORT INTERCONNECT enabled - do I need this ?
2. Is the cabling correct, or should I have one HBA0 to CTLA Port 0 and HBA1 to CTLB Port 1 ?
3. Anything else I am missing ?

Thanks.
