Re: cluster error
shenan,
Is the only connection between the systems formed by the SCSI-cables?
If so, and one node is up, then the other node will not join the cluster, unless you have for instance a LAN connection between the 2 nodes.

Kris (aka Qkcl)

Re: cluster error
Shared SCSI means port allocation class. This is also covered by the CLUSTER_CONFIG procedure.
If set up properly, the console should be able to locate your disks. Including the quorum disk:
>>> SHO DEV
Booting a cluster node on it's own should work without network, as long as the rest of the requirements (VOTES,EXPECTED_VOTES, QDISKVOTES, DISK_QUORUM) are set properly.
In the log of your startup sequence, it should be mentioned that access to this disk has been attempted.
Booting a next node into the cluster _requires_ a network connection: cluster traffic will not travel over SCSI (AFAIK).
If you boot conversational, you would be able to examine the following sysgen parameters:
VAXCLUSTER
EXPECTED_VOTES
VOTES
DISK_QUORUM
QDSKVOTES
What are the values for these?
(SHOW /CLUSTER once booted. In SYSINIT> you may have to access them one by one)

Re: cluster error
>>>this system was configure by myself earlier.. . .yes there is a quorum disk.now the system wont go futher
Is this the first boot since you configured the systems? A quorum disk needs the file QUORUM.DAT. This is created automatically when you start a cluster with enough votes.
For the first boot, you need to inflate the votes so this file is created, typically with an conversational boot. Set votes on one node to 2 (assuming votes=1,expected votes=3) boot that node, reset votes=1, reboot.

If you don't have time to do it right, when will you have time to do it over? Reach me at first_name + "." + last_name at sysmanager net

Re: cluster error
Would both AlphaServer DS10 boxes be booting from the same system root on the same system disk on the same shared SCSI bus?
If so, check the SRM environment variables for the boot flag settings. Specifically, the BOOT_OSFLAGS boot root setting; the leftmost value in the pair.
If you're booting from the same disk using the same system root, you'd see exactly this symptom -- when OpenVMS prevents you from corrupting your disks.
