How join LUN Clariion CX3-80 with HP-UX server?

[Alissa_2]

Good day!
I have a little question about HP-UX. How to join LUN Clariion CX3-80 with HP-UX server? I.e. Have I to mount LUN to operation system manually? Have I to create file system?
Can Hp-Ux server watch this LUN without any actoins?

You need to present the lun to the hpus host. i am not sure of your setup, but that could involve zoning. once you have presented it you need to run

# ioscan -fnC disk

next you need to create a device file for the disk. You can either run

# insf -e

or

# insf -H

then you run pvcreate on the disk and add it to a volume group, or create a new one. Now you can create an lvol and put a file system on it. That is my short version of it.

Haven't touched EMC in awhile but I think you'll need to install Powerpath. Or you'll see many paths for each disk

Shalom Alissa,

Some actions required.

insf -C disk

That and ioscan are your best bet to avoid a system boot.

Officially however a reboot is normally required to get a system to recognize non-HP disk. That last fact may be dated.

Here the important is part is how you present the LUN to the HP-UX host and confirming that is LUNs are visible to host(mostly a SAN admin work).

Once the device/ctd is visible from the host then the remaining part is just the LVM work(system admin)

In this two part where you need more information/help?

I almost forgot. Depending on the array, there is sometimes a host mode selection when presenting luns. You will need to select the correct one for HPUX (I cannot tell you exactly which option to choose). If not, you can run into the issue where the host will only be able to see 8 luns from the array. This may not apply, but something that you may want to look into.

Hi Alissa

Have you registered the HP-UX host with the CLARiiON in "connectivity status" After the zoning this is the next step.
The HOST and LUNS must then be put into the same storage group on teh CLARiiON.
Next ioscan -fnC disk will show the disks, then insf -e will create the CTD numbers.

After that treat then just like any other disk. Remember to turn off BAD BLOCK ALLOCATION as the CLARiiON takes care of that.

Using Navisphere Software of EMC register the HP Unix host(Naviagent installed at HP UX host) to the CX-3 create Storage Groups for this HP box. and also allocate Luns from the Raid groups. like each lun to each Service processer A0 B0 A1 B1 (redundancy is taken care by doing this)

After connecting and zoning the CX-3 to HP Unix box. Run

# ioscan -fnC disk

# insf -e

On host side.

You can see the ctd number of the new Luns allocated... the do the usual LVM creation stuff on HP Host.

Good Luck
