msa-1000 acu

Is there an "array configuration utility" for HP-UX to controll MSA-1000?

Thanks a lot

Re: msa-1000 acu

I don't think so. HP support pages state clearly:
"NOTE: The ACU is available for the following operating systems:
* Windows
* Linux
* NetWare (offline)"

Maybe it will be helpful:

"HP-UX support
Command Line Interface (CLI) is used for configuration and Event Monitoring Service (EMS) for monitoring.
Root/Boot/Dump/Swap/Install is also supported."

Is it possible to share several logical units drives or volumes among several hosts whith different operating systems (at least 3)?

Thanks a lot.

Re: msa-1000 acu

Carlos,

If you are asking specifically about the MSA 1000, then the answer is yes, but not with every OS.

I.e. if one of the hosts runs HP-UX or SCO you cannot mix OS'es:
"HP-UX PA-Risc and Itanium-based server support ... limited, homogeneous configurations.
SCO UnixWare support - ... single controller 2-node homogeneous configurations."

Rgds.

Raadek, our case is:

2 HP-UX Hosts and 1 windows 2003 server.

Re: msa-1000 acu

So it's plain & simple - you can attach these 2 (or even more) HP-UX hosts, but then any host running different OS (like Win2k3) cannot be connected.

Re: msa-1000 acu

OK. It's clear.
Another simply question. Now, we have six disks in raid-5 locating from box bay 1 to box bay 6. Is it mandatory to locate new disk (if I want to create a new LUN) from bay 7 to bay 14?, and can I create it (new LUN) when existing LUN is in use?

Thanks a lot, folks.

Re: msa-1000 acu

You can create a new LUN when another one(s) is (are) on-line.

Re hard drives order:
That's depends on how your drive enclosure (the MSA 30) is connected to the controller shelf (actual MSA 1000). If you use single-port I/O module, then no issues at all - you could plug a disk in any free bay. If you use dual-port I/O module, then bear in mind that bays 1 to 7 are connected to SCSI bus 1 & bays 8 to 14 to SCSI bus 2. However if you have both SCSI channels connected to the MSA 1000, then again - no issues re hard drive position.

But using just common sense I would plug them in order.
Don't panic! [THGTTG]

Re: msa-1000 acu

Raadek,

I have talked whith HP support. They say that it's possible to mix different os's in the same MSA, even Windows 2003 and HP-UX. What does it mean "homogeneous environment"??

Thanks a lot.

Carlos,
"homogeneous environment" means "one operating system".

Re: msa-1000 acu

Uwe,

Then is it possible to share same MSA with diffent os's? I mean creating different LUNs and each of this one conected ONLY with one OS. One of this attached to HP-UX and another to Windows 2003.

Re: msa-1000 acu

According to the latest SAN design guide, HP-UX is not listed in the heterogeneous SAN support (= different OSes) table, so I think the answer is NO :-(

Please keep in mind that many operating systems can deal with both controllers, but it is not possible with HP-UX - you are limited to single path configurations.

If you mix a multi-path OS with HP-UX and the other OS does a controller failover, HP-UX will loose complete access to the MSA1000!

Re: msa-1000 acu

Carlos,

not sure if you're still following this thread, but in reference to your very first question (ACU CLI for HP-UX) - yes, there is now one available for both, MSA1000 and MSA1500, albeit not as powerful as on Linux, for example. Still, you may want to give it a try. It beats accessing the MSA CLI via serial port and Kermit on HP-UX...

Note - follow the procedure below exactly - I've found it difficult to locate the support software cd any other way. Maybe someone can reduce the amount of steps needed other than posting the actual URL (which is http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&prodTypeId=12169&prodSeriesId=415598&prodNameId=415600&swEnvOID=181&swLang=8&mode=2&taskId=135&swItem=co-47048-1 as of the time of this posting).

Here's where you can find the hpacucli and SCU for HP-UX - download this file (even though not HP-UX):

1) go to http://www.hp.com/go/msa1500cs
2) click on "Support for your product" on the right side
3) click on "Download drivers and software"
4) click on "HP StorageWorks 1500cs Modular Smart Array"
5) click on "Microsoft 2000" (yes, even for HP-UX)
6) click on or scroll down to "Driver - Storage"
7) download the "MSA1500 Support Software CD (ISO)" under "Drivers - Storage"
8) open the iso image with Nero Image Drive (if you have) or burn it to a CD
9) find the hpacucli depot for HP-UX on the "MSA1500 Support Software CD" under directory "\HPACUCLI\HP-UX" and the directory for the respective architecture below that
10) find the SCU scripts for HP-UX on the same "MSA1500 Support Software CD" under directory "\HP-UX\SCU" and the directory for the respective architecture below that

Best of luck,
