Suspected Description
Components
Controller As part of its stamp, each
Erroneous drive indicates its logical
Operator position in the disk set to
Activity which it is attached. This
event indicates that the
controller has detected two
disk drives with identical
stamps, indicating that they
occupy the same logical
position of the same disk set.
The most likely source of this
error is the erroneous
assignment of duplicate disk
set ID's by the controller. This
would generally originate with
incorrect controller serial
number assignment, and/or
loss of NVRAM. This error
would also occur if a user
made an image copy of a
drive.
The solution to this difficult
problem involves two steps:
1. Try to determine which
of the disk drives share
the conflicting stamp.
This can be done by
removing disk drives
until the problem
disappears. Concentrate
on any previously used or
unincluded disks first.
2. When you have isolated
the two conflicting disks,
determine which one
contains valid data.
