the second alpha could't boot up on VMS cluster


For my coustomer's project, I should form a VMS cluster V7.3-2, 2 alphaservers(DS10L and AS1200) and one RA3000.


Two alpha's boot from the same disk on RA3000
but,the boot disk name on RA3000 wasn't same,
DS10L was named DKA0(SYS1)
AS1200 was named DKC0(sys0).

Cluster alloclass --->1
QDSK ---> sys$sysdevice

on AS1200:
PORT ALLOCLASS for PKB(local disk) -->98
and PORT ALLOCLASS on DS10L was't set, for just one share SCSI on it.

When I boot the second alpha,
the error message "INCORRECT SCSI CONFIGURATION", the alpha was crash and reboot and crash...

What's wrong?

be sure to have read both cluster manuals (VMS Cluster manual, Guide to cluster configs), which you can find here:
(The best is to read the app. chapters twice :-}, because shared SCSI clusters may become tricky).

In your case, you should define port allocation classes on both nodes to the same value for the shared SCSI bus, so that both nodes see the disks under the same names.
If conflicts exist for the non-shared busses, use the port allocation class 0 on them.

from your Forum Profile:

I have assigned points to 49 of 85 responses to my questions.

Some of those questions tare from more than 2 years back.

Maybe you can find some time to do some assigning?


Mind, I do NOT say you necessarily need to give lots of points. It is fully up to _YOU_ to decide how many. If you consider an answer is not deserving any points, you can also assign 0 ( = zero ) points, and then that answer will no longer be counted as unassigned.
Consider, that every poster took at least the trouble of posting for you!

To easily find your streams with unassigned points, click your own name somewhere.
This will bring up your profile.
Near the bottom of that page, under the caption "My Question(s)" you will find "questions or topics with unassigned points " Clicking that will give all, and only, your questions that still have unassigned postings.

Thanks on behalf of your Forum colleagues.

PS. - nothing personal in this. I try to post it to everyone with this kind of assignment ratio in this forum. If you have received a posting like this before - please do not take offence - none is intended!


Have one on me.
