Hi,
My customer is running OpenVMS AXP 6.2-1h3 FDDI cluster and shadowing with
the following configuration:
------------ ------------------ ----------
| |DEFEA-AA ---|FDDI Concentrator| ---DEFAA-DA| |
| AS2000 | ------------------ |DEC4710 |
| | ------ FDDI ------ | |
| 256MB |DE422-SA --|900EF|-------|900EF|---Ethernet|256MB |
| | - ------ ------ | |
|___________ | _________
|
------------ |
| Dec2000 |----------

Quorum node
Previously, they were having DEC4710 instead of Alphaserver2000 which
is using the DEFEA-AA(EISA FDDI). They experience slower shadow copying
between the two system. Is there any system parameter that can speed up
the shadow copying? How can I determine that the shadow copying and
cluster communication run over FDDI instead of ethernet?
Thks.

Hmm, do any of numbers below look funny?
