itanium qourum disk problem VMS

[WilliamSmith11]

Hi I was booting from an itanium server with operating system 8.2-1

After installing cluster the system does not come up.

My problem may be is the quorum disk , I dont know how add the quorum disk in the way that when the machine is booting be able to see the quoruom like it see the operating system that also is in the SAN.

Thank you

I will appreciate all the help

William,
from your description, it sounds like you are in this situation:

you have set all parameters correctly and the system expects to find the quorum file. As this is a new installation, the quorum files does not exist yet. The quorum file is automatically created by one of the system processes when VMS has done a reasonably part of the boot. Unfortunately, it can't continue the boot, because it is missing the quorum disk's vote(s).

In that case I do a conversational boot on the first node, alter the system parameters so it temporarily has enough votes to continue booting. Later during the bootstrap it will automatically create the quorum file.

I see the storage and the Itanium part .

The software team really I dont know what have done with the OS when try to configure the cluster.

There is some manual tha explain how to add this quorum file on Itanium machines .

In alpha system was possible executing this commands , but un Itanium I dont know how to do that .

>>>boot -fl 0,1
>sysboot
>set spected voted 1
>set startup_p1 "min"

Thank you Uwe

You have to set an environment variable:

Shell> SET VMS_FLAGS "0,1"

I forgot - you can also pass it to the boot loader:
fs#:\efi\vms\vms_loader -flags 0,1

If no system has used the quorum disk,
yet it is defined in sysgen, even if you
set expected_votes to 1, if the system
finds the values for the quorum disk, it
will adjust quorum.

If it is a cluster, you can boot with enough
votes to get past it. Once the systems
are booted, it will write quorum.dat and you won't have this problem again (unless the disk fails).

Another solution is to once boot the system with enough votes to satisfy it.
sysboot>set expected 10
or something like that.
After booting readjusted quorum.

To see if the cluster disk is actually being
used, type
$show cluster/continuous
while that is being displayed type
add qf_vote
a box will appear with a YES or NO.
YES means it is using the quroum disk vote.

Best of luck.

Do you know how to set in itaniam a disk in the same way like alpha.

I mean
in Alpha system was

For example

>>>wwidmgr -quickset id 10

and was possible to see a disk of EVA from the SRM of the alpha server .

How I do this in itanium.

William.

Ah yes, that's a bit tricky. I'm a lazy one, so I boot the OS DVD and run this procedure:
$ @ sys$manager:boot_options.com
