we are running VMS v 6.2 on a DEC 2000.
This will be a boot member in a temporary LAVC, so we are using
a quorum disk.
After running CLUSTER_CONFIG.COM and rebooting we repeatedly
get the message "Error reading quorum disk"
DISK_QUORUM="SYS$SYSDEVICE", VAXCLUSTER=2, EXPECTED_VOTES=1,
QDISKVOTES=1, RECNXINTERVAL=20, QDSKINTERVAL=10.
SYS$SYSDEVICE is a RZ28.
What's going wrong?
The Answer is:
DISK_QUORUM must point to the physical device and not a logical. Use the
device name on the very left of the display from the following command
SHOW DEVICE SYS$SYSDEVICE
Also EXPECTED_VOTES should equal the maximum number of votes ever seen in
the cluster at any one point in time. Remember to count the quorum disk
vote only once.
Also all nodes that reference the quorum disk must also have a direct
(i.e. not a host-servered MSCP drive) path to the quorum disk.
Do not configure a quorum disk on a DEC 2000 -- add the votes to the
host. (There is no dual-port SCSI support for this system, so there
is no way to access the disk when the DEC 2000 is down and thus there
is no sense configuring the quorum disk. Add the quorum disk votes to
the DEC 2000 host votes.)
