Identifying Memory Channel model?

» close window

The Question is:

Is there a way to see which model Memory Channel without rebooting?  I am in
a 24/7 shop, and we want to duplicate the environment of the production
systems, which are in a 2-node Alpha cluster.  I can determine all of the
model numbers of everything else
, but I can't figure a way to find out which Memory channel card we have on
hour system without going into console mode.  Is there a way to do it?

The Answer is :

  Check the Memory Channel controller revision ID using SDA.  More
  specifically, use the SDA command "SHOW DEVICE ddcu/PDT", where
  ddcu is the particular memory channel controller.  For example:
  In the output displayed by the command, read the "Adapter Ver" field.
  MC1 should be circa x0B, MC1.5 is x0E, and MC2 should be 0x020.
  Beware differences in radix.
