Heed these important warnings:
Warning:
A reset is required if you change the mapping type (for example, from
SAN to Affinity), or the topology type within SAN mapping. You can, however, set
things up and postpone the reset until you have some downtime available.
Warning:
If you make a change to the mapping, be sure to consider how the new
mapping might affect device drivers on attached systems. Depending on what you are
changing, you might make the controller invisible to TPM. You also might make one
of your host device drivers now point to the wrong LUN, which could result in data
loss if the LUN is in use. In other words, TPM will not stand in your way if you do
something to configure the system in an undesirable manner.
Warning:
Only the most experienced administrators should make changes in an
on-line environment.
