How to configure P2000 G3 MSA on RHEL 6

[chefchanyu]

Hi all:

I got 2 P2000 G3 MSA in array and connect to 2 HP servers (RHEL 6 OS).

How can I find the SAN storage on RHEL?

and How Can I partioning the SAN drive?

Thanks

Danny

All configuration and management of the array is done via web interface or cli directly on the array.

Do you use fibre channel or iscsi?

[chefchanyu]

should be FC connection. here is my physical FC layout.

[Torsten.]

Point your browser to one of the array controllers and make sure the host port setting of the array is correct for this configuration.

Hi:

Currently those P2000 are new install to the rack no one done anything to it yet.

"the host port setting of the array is correct for this configuration" how to do that?

"Point your browser to one of the array controllers"  I don't  have an the P2000 ip address (do i need to configure one?).

[Torsten.]

Did you ever consider to read the manual?

Connect to the array via telnet/ssh or serial, setup the ports, create a vdisk, create a volume and present the volume to the created hosts.

Look out for

Hi:

my first time install SAN storage for server. Sorry about I am asking very stupid questions. Currently my team mate no one know or has experience how to configure P2000.

my servers and P2000 currently installed in other state.

So Do you mean I have to get someone to configure a IP address on array controller via console port have no other option?

[Torsten.]

If you read the manual you will find the array first try to get a DHCP address, if not available it falls back to a fixed IP. You can also get the USB driver utility and make a serial connection via the USB cable.

[chefchanyu]

Finally going use console port to do the configure. and I got more questions here:

what commands will do to create follow partitions?

• 1GB LUN for the RHEL Cluster quorum device

• minimum 50GB for the MySQL database

• minimum 100GB for the shared data of the FSMSC

• minimum 50GB for the shared data of the Tomcat Servlets

and after that how to find this SAN storage on RHEL server?

[Torsten.]

It still lokks like you did not read the manual so far, right?

Everything is explained there. Configuration details depend also on the number of disks you have, you need to decide if you want to have RAID10 or RAID50 as RAID level.

[chefchanyu]

I did read those following documents:

- P2000 G3 MSA System FC/iSCSI User Guide

- HP P2000 G3 MSA System CLI Reference Guide

- HP P2000 G3 MSA System SMU Reference Guide

but I can't find any command to create a LUN. is it "add unit" command work on P2000, if not what command to crete LUN (I don't see that in P2000 cli reference)?

I am going using level r1 and all 12 hard disk to create each vdisk.

if I want to create mysql vdisk, is it right command to use? but what about the size of MySql?

" create vdisk level raid1 disks 1.1-12 MySql "

[Torsten.]

It is probably an easy way to use the provisioning wizard from the web frontend of the array.

However, you need to do the following steps:

- create a vdisk (RAID10) accross a number of disks

- inside the vdisk create your volumes (LUNs)

- create your host entries (WWNs of the servers HBAs)

- present the volumes (LUNS) to the hosts

relevant CLI commands:

- create vdisk

- create volume

- create host

- map volume

Thanks mate.

currently I still waiting IP address for P2000, and will get some one to plug console from servers to P2000.

than I can access the P2000 remotely via ssh or ILO.

thanks a lot to point out some of those main command go to use. I will SMU when the IP ready.

[Torsten.]

You will need 2 IP addresses, 1 per controller.

[chefchanyu]

Hi:

- There has 2 controllers on each P2000, Do you mean I need to configure both controller with IP? 

- I just got someone plug the console cable from server to P2000 and I am using minicom, but doesn't work. 

My server OS is RHEL6.1 Do you have any idea how to get that working?

- Also do I need to login to each controller to do the configureation? or one controller will do one P2000?

[Torsten.]

The P2000 G3 is using an USB connection to emulate a serial line.

AFAIK there is only a windows driver available. So you need to install the driver, connect the USB cable, look up the COM port and make a serial connection (e.g. COM1).

YOu should give each controller an IP address, otherwise you cannot access it for management, but you do the config on just 1 controller, the config is mirrored between both.

[chefchanyu]

Hi:

I am wondering is P2000 console cable. P2000 cli is mini-USB B to normal serial port?

if that right did P2000 come with the console cable in box? or we have to buy our own cable?

Thanks

Danny

[Torsten.]

This is a standard USB to USB mini cable, same like cameras etc. have.

Just the windows driver "create" a special COM port for the P2000 serial communination port.

[Torsten.]

Make it simple:

take a crossed LAn cable, connect your PC to one of the controllers, configure your PC with 10.0.0.3 or something.

here are the defaults of the controllers:

Management Port IP Address:
10.0.0.2 (controller A),
10.0.0.3 (controller B)
IP Subnet Mask: 255.255.255.0
Gateway IP Address: 10.0.0.1


If your network has a DHCP server, connect the controllers to the network and use this tool from a windows PC to find the P2k:

[chefchanyu]

Yes this is most easy way.

I will get some one go down to the exchange cable up a point to point connection.

[chefchanyu]

So 1 management port will able to access to both controller via 10.0.0.2 and 10.0.0.3? is that right?

[Torsten.]

No, the upper controller has

10.0.0.2

the lower controller has

10.0.0.3

Hi:

I had create 2 vdisk with raid0 (3 x 2 disk).

than I want create raid1 with this 2 vdisk, how can i do that via SMU?

Thanks

Danny

[chefchanyu]

Hi:

I guess Raid 10 would be right one.

500143801206d22e is my FC port on server 1. that was found by P2000 itself.

it did match to /sys/class/fc_host/host2/device/fc_host/host2/port_name.

and I map all volums under that, but I can't find any volums in the server (commands: ls /dev     fdisk -l  ).

I don't where I went wrong.

[akb_77]

Hi dear, I am also facing the same problem.

I can see host3 and host 4 on /sys/class/fc_host/host3/........

I have P2000 G3 with only FC cable connected to my HP Proliant DL580 P7

I have made two LUN on my P2000. But I am not able to mount and/or look on my server. could you get any solution. Any help would be appreciated in this regards

Thanks
