va7400,disk array 2405 and brocade connectivity ????

We have recently purchased 1 VA7400 , 1 2405 Disk Array and a brocade switch . Can anybody tell me their connectivity diagram and basic commands to configure the disk drives to a HP host. What do i need to run the commands - s/w or any connection to VA7400 serial port.

Connectivity means - like Cable from VA7400(Disk FA or Host FA to where - switch ??)
What types of cable we need ?
HOw to connect 2405 disk to VA7400 ???
and then after connection , how to run the commands .

I know the zonning part .

I didn't recd any mannual with VA7400 and 2405 disk arrays. Any quick help will be appriciated.

As far as the software you need, you should have received CommandView software with the VA7400. If not, call your vendor, or HP to get it. it's necessary to have this to set up the LUNs on the VA7400.

You need fibre channel cables. Connect the DS2405 to the VA7400 by running the FC cable from the 'disk' port on the VA7400 to one of the ports on the DS2405. repeat this step for the additional controller, if applicable. How you specifically connect to the switch depends on your particular setup. The connection should be from the port that says 'host' to the switch.

With as much assistance as you need, I would call HP to have the va7400 installed. The setup of the VA7400 is fairly complex. Also, HP will probably have to reseat the controllers after shipping.

Re: va7400,disk array 2405 and brocade connectivity ????

I was going through the steps :

- How do set FC loop speed to 1 GB ?? Do i need to open VA7400 or 2405 and change something ???

- I have 2 controllers on 2405 - port 0 and port 1 for first controller and port 0 and port 1 for second controller . On VA7400 , 2 controllers - FC and Disk for 1 first controller and FC and Disk for 2nd Controller . That means i can connect port 0 on first controller of 2405 to Disk port on VA7400 on first controller and same for other one . But then what is use for 1 extra port on each controller on 2405 ? Is this for expansion .

Also , can i download the depot for Command View S/w .

i read the mannual and got the answer for how to change the FC loop speed. So don't reply for that .

The purpose of the second port on the DS2405 is to add more ds2405 enclosures. you can have up to 6 connected to one va7400.

Set default host port behavior for controllers 'mgr -os', then format VA. Connect it and a host to the switch, install CommandView to the host and manage VA using it.
CommandView is not downloadable. You should have a copy with your VA, or contact HP to obtain one.

PS. Did you find links I've posted above so unusable?
PSS. Which firmware VA has?

What O/S are you running on the host?

Re: va7400,disk array 2405 and brocade connectivity ????

Iam going to connect to HPUX host only . Don't know about whcih Firmfirm either . Till i get my commandview CD , i have done the following

- formatted the array using - vfpfmt command
- then created a LUN 0 using cfg -L 0 -a 8 -g 1 command .

- then i connected all the cables fm 2405 to VA7400 and VA7400 to switch and also hp host to switch . I logged into the switch and zonned my host HBA to both FA ports . Is this ok ??

Can i do anything now till i get commandview CD.

Those mannual were of great help .
Thanks

I think that now you can create more LUNs and try doing 'ioscan -fn' and 'insf -e' on the HPUX server to see if it will see VA LUNs. It should work

Thanks for the help. I can see LUN 0 on the HPUX host . So is this means i don't need to wait for command view to be installed . I can just go ahead and create any number of LUNS (any size) as i need.

Right. Although serial port has very limited capabilities so you will need Command View to manage VA anyway

Re: va7400,disk array 2405 and brocade connectivity ????

finally i got the command view installed . and created the luns and everything looks ok. few things i need to clarify

- How do i make a particular LUN not seen by other host (without buying another HP product ) or some other workaround is ok . I just want to make sure that i don't use a LUN used by other host by mistake .

- Is the command view has some gui ? where i can how many disk i have , how do they are distributed among controllers.

- When i create LUNs , i create even on RG 1 and odd on RG 2 . Is this is right approach . Also when i create a VG , i make sure that i choose the correct devices in order to do load balancing between 2 controller . Is this is how it is be done .

- Any more suggestions are welcome .

That may be last post for this question . Thanks everybody for guiding me .

Yes there's a gui. Refer to the manuals on the CD-ROM (under the 'docs' directory) around page 69 of the 'cvsdm_usersguide_v10601.pdf' file.

--> When i create LUNs , i create even on RG 1 and odd on RG 2 . Is this is right approach .

That is the correct way to do it.
