<p class=3DMsoNormal>With failover, it is my understanding that omshell can=
be
used to force a “partner-down” state so that the primary server=
can
issue all leases, including those marked as “backup”. I h=
ave
tried the following:<o:p></o:p></p>
<p class=3DMsoNormal><o:p> </o:p></p>
<p class=3DMsoNormal>1. Start primary and failover servers with a sha=
red
pool of ten addresses.<o:p></o:p></p>
<p class=3DMsoNormal>2. Request all ten leases from the primary, usin=
g
clients on the configured subnet.<o:p></o:p></p>
<p class=3DMsoListParagraph style=3D'margin-left:.75in;text-indent:-.25in;

e'>1.<span
style=3D'font:7.0pt "Times New Roman"'> =
</span></span><![endif]>In
v3.0.6, I can get seven of the ten leases before the primary complains that=
the
“peer holds all free leases”<o:p></o:p></p>
<p class=3DMsoListParagraph style=3D'margin-left:.75in;text-indent:-.25in;

</span></span><![endif]>In
v3.1, I can get eight of the ten leases before the primary complains that t=
he “peer
holds all free leases”<o:p></o:p></p>
<p class=3DMsoNormal>3. Stop the failover server.<o:p></o:p></p>
<p class=3DMsoNormal>4. Attempt to get all ten leases again, still ge=
t 7 or
8 depending on DHCP version.<o:p></o:p></p>
<p class=3DMsoNormal>5. Wait MCLT seconds and attempt to get all ten =
leases
again, still get 7 or 8.<o:p></o:p></p>
<p class=3DMsoNormal>6. Use omshell to connect to the primary server =
and
set the local-state variable of the failover-state object to 1 (3.0.6) or 4
(3.1) to force “partner-down”.<o:p></o:p></p>
<p class=3DMsoNormal>7. Attempt to get all ten leases again, still ge=
t 7 or
8 depending on DHCP version.<o:p></o:p></p>
<p class=3DMsoNormal>8. Wait MCLT seconds and attempt to get all ten =
leases
again, still get 7 or 8.<o:p></o:p></p>
<p class=3DMsoNormal><o:p> </o:p></p>
<p class=3DMsoNormal>From the information I’ve been able to locate, t=
hese
steps should allow the primary to be able to give out all ten leases, but i=
t
does not. Is there something I’m missing?<o:p></o:p></p>
<p class=3DMsoNormal><o:p> </o:p></p>
