Help configuring MSA1000 storage under 11.31

Guys,

After spending most of the day trying to get my Itanium server to recognise the MSA1000 storage we connected to it I now need to create device files for the storage or better still just get the whole lump of storage put into a Volume group. Can anyone give me any pointers as to where to start (whole new ball game san storage on HP-UX to me)

Here is what we have :-

Hi Mike,


can have a look at the following thread, This talks about the MSA1000 and the HP-UX 11iv3.

Re: Help configuring MSA1000 storage under 11.31

Hi Mike,

the MSA needs to have dual controllers and active/active firmware. All LUNS must be presented with profile "hp" (for hp-ux) to hp-ux servers. If SSP is enabled, you need to configure it.

Check this either with the CLI (serial connection to the array)
CLI> show tech_support
or with ACU from a connected windows or linux system.





IMHO the configured profile for the LUN is at the moment different from "hp" for hp-ux - maybe "default" or "windows", this is wrong and cause problems.

Hope this helps!
Regards
Torsten.

Re: Help configuring MSA1000 storage under 11.31

Guys,

Thanks for the replies.

Torsten - i've just spoken to our storage administrator and he tells me our MSA is active/passive and not active/active as you mention.

Are you 100% it won't work unless it's active/active ?......he's not keen to change this so as I see it i'm snookered here :-(

OK I guess it's this link you are refering to :-

http://docs.hp.com/en/9529/hpux_io_devices.htm


Would explain why ioscan is not finding any MSA volumes...

# ioscan -fnC disk

Re: Help configuring MSA1000 storage under 11.31

I assume it is a blade server, right?

You need to check

- zoning on switches
- SSP on MSA (selective storage presentation)

hp-ux cannot work with active/passive devices, because it would cause the controllers to switch permanently.

Maybe a single controller may work.

Important thing is to set hp-ux as hostmode on the MSA.

Hope this helps!

Torsten.

Re: Help configuring MSA1000 storage under 11.31

Torsten - it seems pointless looking further at this as it seems we aren't going to be able to get it working until it is changed to Active/Active anyway ?

Re: Help configuring MSA1000 storage under 11.31

AFAIR the MSA1000/1500 in active/passive was never supported by hp-ux; only active/active or single controller.

Hope this helps!

> AFAIR

100% - A/A or single controller.

Re: Help configuring MSA1000 storage under 11.31

fwiw.

IMHO is is 100% an HPUX question, where it was first posted. At the time of my reply it is moved to 'storage'. Yes it pertains to how storage, but strictly how it is used under HPUX.

Af for the original question: "just get the whole lump of storage put into a Volume group" I am a fan of presenting as few as possible device to the OS and have to Storage controller do as much as possible of the work (striping, cacing, whatever).
I'm not even sure I would 'bother' with LVM at all. Just use the device!
