How to configure a LUN with information in an HP-UX 11.31
i hope you can help me. I have a Production and Test servers both are HP-UX 11.31. The production server has a Production LUN in an EVA4400 working perfectly. In the same EVA4400 i did a snapclone or copy of Production LUN called Test LUN. Test LUN was presented to Test Server (All is configured correctly from Storage side). The question is "how i can configure TEST LUN (The TEST LUN has information)in TEST Server".
Lukas
Thanks

Once storage temp assigned lun to your server you can see them with
"ioscan -fnC disk"
once you see your new luns then you can create VG and LV,
same as how we create vg and lv.

Re: How to configure a LUN with information in an HP-UX 11.31
now you need to run vgchgid and vgimport (or just vgimport, if this is a different server).
Hope this helps!

Torsten.

- On the Test Server you can do following to use the cloned lun:
1. # ioscan -fnC disk
2. # mkdir /dev/vg_name
# mkdnod /dev/vg_name/group c 64 0x100000
(minor number must be unique)
3. # vgimport vg_name
or if you have a mapfile :
# vgimpor -v -s -m vg_name.map vg_name
[ If you have the map file and copied to current directory. ]
[ You can use -N option to import the vg in agile mode ]
4. Activate the vg:
# vgchange -a y
5. # vgdisplay vg_name
- You can mount the FS's at this point.
Cheers,
Raj.

Re: How to configure a LUN with information in an HP-UX 11.31
When the LUN is cloned, it must be presented to the new server by World Wide Name.
This information can be obtained by fcmsutil.
What I'm assuming here is that you used an EVA utility to clone the LUN. This does not automatically configure the LUN for use by another system.
There may be an option in the EVA software for this, but maybe not. Check that the LUN is presented with World Wide Name information that is correct for the receiving system.
