Chapter11 CWM to CWM Communications
Recovering From Degrade Mode
The following is an example of the downe d P ri mar y ’s DomainGatewayList. Remove all Sec on d ar y
CWMs from the downed Primary’s DomainGatewayList leaving the Primary cwmws1 in its own
domain:
Debug level 2
DomainGatewayList cwmws1
ForcedSwitchOver
HeartBeatInterval 20
Step 3 Stop the core on the downed Primary CWM (to pre vent communic ation with th e Second ary CWMs whi le
the Primary is down and isolated ).
Step 4 Stop the core on the Secondary CWM that has been selected as the new Primary. In this case, for
example, let’s say that cwmws2 has been selected as the new Primary.
Step 5 Edit the new Primary’s DomainGate w a yL is t so that it only has itsel f li ste d. For example:
Debug level 2
DomainGatewayList cwmws2
ForcedSwitchOver
HeartBeatInterval 20
Step 6 Start the core on the new Primary CWM (in this example it would be cwmws2). A message will appear
on the CWM console announcing it as the new Primary.
Step 7 Stop the core on the Secondary CWM (in this example it would be cwmws3).
Step 8 Edit the Secondary’s DomainGatewayList so that it includes itself and the new Primary. For
example:
Debug level 2
DomainGatewayList cwmws2 cwmws3
ForcedSwitchOver
HeartBeatInterval 20
Step 9 Edit the new Primary’s DomainGatewayList so that it now includes itself and the secondary CWM.
For example:
Debug level 2
DomainGatewayList cwmws2 cwmws3
ForcedSwitchOver
HeartBeatInterval 20
Step 10 Start the core on the Secondar y C W M ( in t hi s exa m p le it wo ul d be cw mw s3 ) .
Step 11 Repeat steps 7-10 above to include any additio na l Se condary CWMs in the new domain. The
DomainGatewayList on all of the Secondary CWMs must match the final DomainGatewayList on
the Primary CWM. This li st will include the new P r im ar y and all new Seconda rie s in the new
domain.
The Primary CWM has lost IP or physical connectivity with the only Secondary
CWM in a domain
Note In a situation where there is a Primary CWM and only one Seco ndary CWM in a given domain,
and connectivity between th e tw o CWMs is lo st, ano ther Sec on dary C WM wil l need to be ad ded
to the domain before stopping the core on the original Secondary CWM.
