Re: disc array VA7100

Hi Lipens.
armdsp -i gives me "invalid option" message

I must note that im connected directly to ths disc array and have no unix available.

according to something I researched about 5 minutes ago, the instrction to format the array is:

armfmt -f -h


1. is there any other way to obtain the array id?
2. what would happen if a just executed armfmt by itself ?

Re: disc array VA7100

Hello again.
I was on a lunch break, sorry for the delay.

The thing is:

The VA has a port to connect a console on the back, And im connected to this port Im not interacting with unix to mi knowlodge,

Why did I connect to this port, I was told that in order to format the array i needed to connect here.

I am being displayed a prompt like these one:

No map>


And in this prompt, commands like:
armdsp
armdsp -f
vfpdsp
vfpdsp -f

are accepted.

Also i must note that in the front of the VA
the green LED is on
And the Ambar LED is flashing.

Re: disc array VA7100

Other way to obtain the array id is:
vfpdsp -e
and take Serial Number.
Command armfmt accepts as array-id also Serial Number of VA.
Take http://www1.itrc.hp.com/service/cki/docDisplay.do?docLocale=en_US&docId=200000079881084 to troubleshooting of VA and LED status indications.

Re: disc array VA7100

Hello Lipens

Formating of array is complete, but now there is a message that says, "Not enough disks", I only have 3 disks in the array, I read that you need a minimum of 4 for the array to work, is this true?, and if it is can this by bypassed?

Re: disc array VA7100

You can connect serial console to COM port (back view of VA) and run
>fmt
it can format array.
Minimum disks required is 4.

Re: disc array VA7100

I connected serial console to COM port (back view of VA) and runned
>armfmt
It displayed this message when I executed armfmt.

Format array: clear all data (yes/no)

Formatting subsystem


Not enough disks


I must note that

armfmt -h -i
Did not work

Re: disc array VA7100

Can you post the output of the serial port here?

dsp -c -d -e -f -s

please?

Kind regards,

Re: disc array VA7100

Okay, so... till now, you've tried a format command from the VFP and after it completed, the array went into a "Not enough disks" state. The minimum number of disks needed before you do a format of the array, is 4 disks. Now, you can insert a disk and then again execute the format command from the VFP. The array must come back to a ready state after that.

Re: disc array VA7100


Hello again.

Just starting my shift, so sorry for the delay,

outputs for this command (dsp -c -d -e -f -s) are pretty long and since i dont have a network connection it would take pretty long to get them to you.

what is it you want to know, maybe I can summerize for you?.



The thing is i dont have that extra disk, can this be bypassed?, can the array only work with 3 disks, I need this array for a small project I just want it to work, its not important if it does not work to its full capacity.

Re: disc array VA7100

AFAIK, the array HAS to have 4 disks in order to operate. Its something to do with the way the VA does RAID striping for RAID0+1 and RAID6. And this cannot be changed. You have to find another disk if you want to get the array up. Once you find a disk, a simple format command from the VFP should get it to ready state (Assuming everything else, like the batteries, etc are fine).
