Chapter1 1 CWM to CWM Communica tions Recovering From Degrade Mode
Step 11 Repeat steps 7-10 above to include any addit io na l Secondary CWMs in th e new domain. The
DomainGatewayList on all of the Second ary CWMs must match the final DomainGatewayList on
the Primary CWM. This list will include the n ew P rimary and all new S eco n d a rie s in the new
domain.
One Secondary CWM has lost IP connectivity wit h t h e Pri m ary CWM
– To recover from this d e gr aded mode of ope ra tion , re -e stabl ish IP c onn ect iv it y on th e Se cond ar y
CWM, and the Secondary CWM will automatically re-sync th e user data tables with the Prim ary
CWM.
Note IP Connectivity is still mainta ined between the Primary CW M a nd the other Secondary CWMs
in this scenario. Only the Secondary CWM that has lost IP connectivity with the Primary CWM
will be working in the degrade mode unti l its IP conn ectivit y is re- estab lis hed.
The CWM Gateway process dies on the Primary and is NOT restarted by
watchdog
– To recover from this degrad ed mode of operation, warm start only on the Primary CWM. In this
case the original Primary CW M is still the designated Prim ary CWM, and the Secondary C WMs
automatically re-sync user data tables.
Note User data provisioning is still in progress on the Primary CWM without the CWM Gateway
process running. Additi onally, in this case, the Primary C WM still has connectivity w it h all
Secondary CWMs.
– If a Warm start does not work, then eliminate the downed Pr imary from the CWM domai n by
following these steps:
Step 1 Manually remove the dow n ed Primary from all the ot he r CWM’s DomainGatewayLists in the
CWMGateway.conf file
The following is an example of a CWMGateway.conf file with a DomainGatewayList consisting of
three CWM workstations named c w mw s 1, cwm w s2 , a nd cwmws3, with cwmws1 ass i gned as th e
Primary and cwmws2 and cwmws3 a s sig ne d as S e co nd arie s:

The above DomainGatewayList, for example, would n eed to b e edit ed to sho w that the do wne d Primar y
has been removed from all the other CWM’s DomainGatewayLists in the CWMGateway.conf file. In
this example, you would remove th e d owned P rim ary from both cwmws2 and cw m w s3
DomainGatewayLists to include only cwmws2 and cwmws3 Secondaries in the same domain:
