When the main server goes offline and the services start on the other server
you may have to do a number of things to get the primary server online.
Normally after you fix it you can restart the cluster service but fixing the
server may require a reboot.

Now when the groups fail over to the secondary server (you are implying
active/passive in your email) the sql service has actually has stopped for
all practical purposes on the primary server and is trying to start up on
the secondary server.  The dependencies have to start first.  Netbios names,
IP addresses, disk resources, etc.  If you were in the middle of a large Tx
a lot of things may occur depending on what caused the primary to fail.
>From my experience  it seems as if you have to reconnect to the database
since the sql service, in effect, has been restarted.  Unless your desktop
app makes continuous retries to redo the odbc connection you may have to
restart the desktop app (i.e. close and open) in order for it to work.

Hard Drive failure? You mean the shared scsi device? you have hardware RAID5
(or you better have).
or the sys/boot drives on one of the nodes? - yes it will take serveral
minutes for the other server to pick it up.  I have seen in some cases that
if the service did not start in a timely fashion (it said 'starting'- be it
sql or exchange) that I have had to stop it and start it manually even
though this is not supposed to be the case.

Is it true that in a Windows 2000 Cluster scenario (SQL Servers in my case)
that when a failover occurs, you must reboot the server that is now primary
in order for clients to connect?

Also, if there is a harddrive failure in Server A, does it actually take
Server B several minutes to respond?
