Create LUN

I need to create a LUN. Is this something you normally do yourself or do you contact HP? Are there any easy steps to follow?

Re: Create LUN

What type of disk array are you creating a LUN on? Most arrays you should be able to create a LUN yourself.

Let us know the type of array and we might be able to help more.

Re: Create LUN

If you mean to create a new disk device, all you do is this..

ioscan -f
insf -e


Then ls -lrt /dev/dsk to see your new devices.

Re: Create LUN

I have a 7110 Array.

Re: Create LUN

Creating LUNS depends usu on your h/w support for the array.

In my case EMC installs new disks which are sized for LUNS and allocated and then are manipulated with EMC tools for zoning and mapping to my host.

You probably need technical support from your vendor.

Re: Create LUN

With the VA7110, you should have the CommandView software installed, and you can use the armcfg utility or create it through the GUI launcher utility.

This manual for the VA series is your best bet for getting started...

Re: Create LUN

man armcfg

From memory..

# armcfg -L -a

n is the LUN number.

then
# ioscan -f
# insf -e
# ioscan -f

Re: Create LUN

And if you dont have command view SDM you can connect a serial console to the RS232 port of the VA array and use the following commands to configure,

vfphelp Displays a description of each command.
vfpsetup Performs Virtual Front Panel configuration.
vfpdsp Displays subsystem status.
vfpcfg Performs subsystem configuration (LUN creation).
vfpmgr Performs subsystem management operations.
vfpfmt Performs an subsystem format.
vfprbld Performs rebuild operations.
vfprecover Performs NVRAM recovery operations.
vfpsecure Performs security operations.
Vfplog Displays Logs


To Create a LUN:
vfpcfg -L -a [{G|g}|{K|k}] â g

To delete a LUN:
vfpcfg -L -d


(vfpdsp will show you the array ID)
