Sir,
I have create the LUNs (0,1,2,3)on array VA7110. Now I require steps to create the Logical volumes and the file system so that I can create the mount poit to get the working space on the Array.
I have already installed the Commndview SDM. The Server is HP9000 rp3440. The Array is connected through SAN swith 2/8V

Pl guide me to configure the same.

Hi Neeraj,

The VA7110 comes with a very easy to use GUI and MUI. if you've installed commandView, then just type cvui at the hp-ux prompt and you can go through the menus to configure the LUNs.

Also, the CommandView CD-ROM has a complete manual on the setup and configuration of CommandView.

Neeraj,

Step by step procedure is below.

1. login as root on HP UX server
2. #ioscan (Make sure new LUNs are visiable)
3. insf -e (It will create device file for new LUNS)
4. vgcreate
5.lvcreate
5. newfs
6. mount

If you ar enot familer with these commands you can use sam to do this
#sam

it's GUI tool

Now which device I have to select for creating the group. c11 or c13. And why its showing two device names.

Hi neeraj,

C11... = Primary Path &
C13... = Alternate Path.

Or you can take it vice-a-versa....

Example :
C11t0d3 is same LUN as c13t0d3 but there are 2 paths for that single LUN for redundancy.

see man vgcreate for how to mention these alternate paths... while creating a volume group.
