When a array is sipped from the factory, both (primary and secondary) SCSI
Ids are set for the two default drive channels, 2 and 3.  For example,
here we can see that the primary ID (PID) for drive channels 2 and 3 is
14, and the secondary ID (SID) for those same drive channels is 15.
Ch  Type    Media   Speed   Width  PID / SID
--------------------------------------------
0  Host    FC(P)   2G      Serial  41 / N/A
1  Host    FC(P)   N/A     Serial  N/A / 42
2  DRV+RCC FC(L)   2G      Serial  14 / 15
3  DRV+RCC FC(L)   2G      Serial  14 / 15
4  Host    FC(P)   2G      Serial  43 / N/A
5  Host    FC(P)   N/A     Serial  N/A / 44
6  Host    LAN     N/A     Serial  N/A / N/A
Sometimes, when multiple JBODs (just a bunch of disks) are attached to the RAID array, host
channels are "converted" to drive channels.  When a host channel is
converted to a drive channel, it is necessary to also set PIDs and SIDs
for those two channels.
If only a PID is assigned to these new drive channels, as seen here:
Ch  Type    Media   Speed   Width  PID / SID
--------------------------------------------
0  Host    FC(P)   2G      Serial  41 / N/A
1  Host    FC(P)   N/A     Serial  N/A / 42
2  DRV+RCC FC(L)   2G      Serial  14 / 15
3  DRV+RCC FC(L)   2G      Serial  14 / 15
4  Drive   FC(L)   2G      Serial  119 / N/A
5  Drive   FC(L)   2G      Serial  119 / N/A
6  Host    LAN     N/A     Serial  N/A / N/A
then the disks physically attached to channels 4 and 5 can ONLY be used in
LDs assigned to the primary controller.  If an attempt is made to change
the LD controller assignent of an LD with disks using channels 4 and 5,
the error
"Secondary Controller SCSI Id Is Not Assigned"
would be issued.
This is easily fixed.  In the firmware interface:
select menu entry: view and edit channelS
select drive channel 4
select menu entry: Secondary controller scsi id
this will print an acceptable range of IDs for you to choose from.
before resetting the array, go back, do that SAME thing (and use the
same ID for drive channel 5, and THEN reset the array (obviously
stop all i/o first).
After correctly assigning a secondary SCSI id, the output from 'show
channels' would look something like this:
Ch  Type    Media   Speed   Width  PID / SID
--------------------------------------------
0  Host    FC(P)   2G      Serial  41 / N/A
1  Host    FC(P)   N/A     Serial  N/A / 42
2  DRV+RCC FC(L)   2G      Serial  14 / 15
3  DRV+RCC FC(L)   2G      Serial  14 / 15
4  Drive   FC(L)   2G      Serial  119 / 120
5  Drive   FC(L)   2G      Serial  119 / 120
6  Host    LAN     N/A     Serial  N/A / N/A
