CMG-DCM
Flash Status
This section reports the current contents of the DCM's Flash storage. There may
be one or several partitions of Flash memory in use. If a partition is not in use, it
will be empty aside from the standard directory lost+found. Otherwise, one
or more GCF-format files will be shown, together with each file's size in bytes
and the time it was created (Unix ctime).
Tamper lines
This section, if present, reports the status of the tamper lines relayed to the
DCM over an external State of Health interface:
Input State Last Closed (Low) Last Open (High)
0 open (never) Wed Jul 7 16:04:48 2004
1 open (never) Wed Jul 7 16:04:48 2004
2 open (never) Wed Jul 7 16:04:48 2004
3 open (never) Wed Jul 7 16:04:48 2004
4 open (never) Wed Jul 7 16:04:48 2004
5 closed Wed Jul 7 16:04:48 2004 (never)
6 open (never) Wed Jul 7 16:04:48 2004
7 closed Wed Jul 7 16:04:48 2004 (never)
8 closed Wed Jul 7 16:04:48 2004 (never)
9 closed (never) (never)
10 closed (never) (never)
11 closed (never) (never)
12 closed (never) (never)
13 closed (never) (never)
14 closed (never) (never)
15 closed (never) (never)
The columns in the table give, in turn, the current state of each switch and when
it was last observed to be in each state. The above example shows a typical
reading for a set of 9 tamper switches that have not triggered: the normally-
closed switches show the current time under “Last Closed”, and the normally-
open switches under “Last Open”. All other fields show (never), indicating
that no switches have been observed in the “wrong” state since the DCM was
last booted.
Disk Status
This section reports the current state of the DCM's primary hard disk. The
module looks on its USB interfaces for an on-board USB hard disk to use as its
primary storage medium. If no suitable storage medium can be found, you will
see the message Failed to find a USB disk.
Assuming that the DCM successfully found a primary hard disk, you will see
information in a format like this:
FAT32 filesystem has 15 G bytes free
Partition is 37 G bytes (78140097 blocks of 512 bytes)
