Need help with Alpha Server DS20, I AM VERY NEWBE

[Daniel Leblanc]

I all,

I was drop a job of configurating a AlphaServer DS20 for hard drive mirror,i have install 4 hard drive of 18gig i need to configure it for 2 to mirror, so i can drop a Open VMS image on it.

I am windows specialiste never work with alpha server.

Hi Daniel,

First you'll need to work out what RAID controller, if any, is installed in the server.

Being a DS20, it might have a KZPAC controller, otherwise known as a SWXCR controller...

Hopefully when the machine boots, you'll get to a screen with a prompt like P00>>>

Try issuing a show device to see what hardware you've got...

Hope this helps,

Regards,

Rob

Image how new i can even see anything when i boot on my screen plug in the serial port 1...ouchh..i think i am doing something wrong?

[Daniel Leblanc]

Ok finaly got something P00>>> on my screen

Ok so i did show device and this is what i got finaly,

Hi,

Not sure if you've found it yet, but you can get the DS20 documentation here:

Cheers,

Rob

[Rob Leadbeater]

OK. That doesn't look as though there's a RAID controller installed, as you can see the individual disks, although I don't recall the exact device names for the various SCSI cards etc.

I'd be tempted to take the lid off and see exactly what's inside the box...

Open the front door, and you'll find a small latch which unlocks the top cover. Slide it backwards. The sides will then slide off backwards as well, but they can be a tight fit...

Cheers,

Rob

Ok i will lunch and comeback with this in 90min,THANK YOU!!

[Rob Leadbeater]

Just remembered... Be careful with the top cover. There's an microswitch in the top of the server which the cover pushes against when in place - to prevent the server powering up without the cover installed. This switch can break quite easily...

Cheers,

Rob

[Daniel Leblanc]

I want to be able to do this:
Drive #1 to mirror to drive #2
And drive#3 to mirror to drive #4

Gone ton lunch now see you in 90 min

[Rob Leadbeater]

You might want to look at the output of a

P00>>> show config

as well. That should break down the PCI buses...

Cheers,
Rob

[Daniel Leblanc]

Ok done it...but it about 5 screen long ..all i see is PCI config ..last screen..is there a way to make it stop every screen?

[Rob Leadbeater]

... should be able to IIRC ... Try:

P00>>> show config | more

OK. It doesn't appear that you have a RAID controller installed...

It looks like you have one SCSI card (pka0) connecting the CD-ROM (dka500) and another (pkb0) that the four 18GB disks are connected to.

If you want to do hardware RAID then you'll need to obtain a supported controller.

The options list you can find here:

http://h18002.www1.hp.com/alphaserver/options/asds20/asds20_options.html

Basically you're looking at one of the following three cards:

KZPAC-AA Single channel 4MB cache
KZPAC-CA Three channel 4MB cache
KZPAC-CB Three channel 8MB cache

Please double check the installed hardware though to make sure I'm right !

Another option would be to use software mirroring within the OS, although as you're coming from a Windows background you'll probably feel more confident with hardware RAID...

Cheers,

Rob

What is this card KZPCM-DX ,i open the server to look inside

[Rob Leadbeater]

Hi,

KZPCM-DX, if I recall correctly, is the spares number for a KZPCM-DA.

This is a PCI 2-port UltraSCSI single-ended adapter and 10/100 Mb Ethernet combo adapter.

Cheers,

Rob
