Cabling P411 to D2700

Allen Huang_1 — Wed, 23 Feb 2011 17:35:56 GMT

I was going to hook up two SAS cables from the P411 controller to I/O module A and B on the D2700 SAS Array. There was this note in the packaging from HP saying not to connect up to the I/O module B since we have a P411 6Gb SAS controller so I only hooked up one SAS connection. That's confusing since we have two ports on the P411 and two ports per I/O Modules on the D2700. I've never connected up one of these before. What's required (multipath I/O driver plus whatever else) to hook this up so we have redundant channels?
What's the best practices for wiring a P411 to D2700?

I hope the user guide will help you. Page no 36.

Thanks, but do this mean you cannot use the 2nd controller as a redundancy path if I'm using a P411 card?

Similarly, I want to connect 2 cables from my P411 to my D2600. I've been advised that this is supported only if I have Smart Array Advanced Pack, an add-on license. You also must have dual-port SAS drives in the D2000 enclosure. I found HP offers a 60 day eval license for Advanced Pack and deployed that. On HP-UX that is done using this command:

sautil <device_file> license_add_key <license key string>

So far I have not found any specifics on doing the actual array config for dual paths, though. If anyone has that (using saconfig on HP-UX) please advise!

I was told one path will be active and the other passive, so there's no load balancing, just provides a failover path if one port or cable fails.

I was hoping to do this using 2 separate P411s and have tolerance for a complete P411 failure, but that's not supported on the P411s.

Hi All,

Is there any limitation of how many StorageWorks D2600 and D2700 enclosure that I can daisy chained with P411 SAS Storage Controller ?

Any documentation would be greatly appreciated.
