Re: Presented LUNs

Shalom,

You should be able to present at least 8 LUNS from the EVA/4000 to HP-UX

Depending on OS level and driver installation since all this hardware is pure HP you should be able to add many more.

If you are having trouble, please add an error message.

Re: Presented LUNs

What version of HP-UX? Only v11.00 and earlier had problems with >7 LUNs and even then there were ways around it and patches etc.

You can present as many LUNs as the EVA can manage to HP-UX without an issue...

The OS is HP-UX 11.23 MCOE
The Storage is EVA 4000
But the OS can not recognize more than 7 LUN.

Re: Presented LUNs

Well that config is supported and works, so something is wrong somewhere,

Care to share some more detail (such as what actions you take to present more vdisks. step by step)?

You did make sure that HPUX was slected as the operating system when presenting the vdisks from Command View didn't you?

Re: Presented LUNs

Most of the times you will see strange problems if you present LUNs in other host modes than hpux (e.g. default, windows).

Check the presentation mode!

In this example it's LUN10:

disk 3 1/0/9/1/0/4/0.13.4.0.0.1.2 sdisk CLAIMED DEVICE HP
HSV200
/dev/dsk/c2t1d2 /dev/rdsk/c2t1d2

Hope this helps!
Regards
Torsten.
