Solution  1003545.1 :   Sun StorEdge[TM] 3510:How to restore a missing back-end (drive channel) loop.

Symptoms
3510's should show 2(3) under the "chl" column in
"View and Edit SCSI Channels".

If the disks show only "2", and not "2(3)", how can I fix this?

Resolution

First, verify that both channels 2 and 3 are DRIVE channels, since it
is possible to change one of them to be something other than a drive
channel:
sccli> show channels
Ch  Type    Media   Speed   Width  PID / SID
--------------------------------------------
0  Host    FC      2G      Serial  40 / NA
1  Host    FC      2G      Serial  38 / NA
2  Drive   FC      2G      Serial  14 / 3
3  Drive   FC      ASYNC   Serial  14 / 15
4  Host    FC      ASYNC   Serial  44 / NA
5  Host    FC      ASYNC   Serial  NA / 46
6  Host    LAN     N/A     Serial  NA / NA
If they are both drive channels, the PID/SID on both drive channels
should be the same (defaults are 14/15).  As you can see on this array,
the SID of channel 2 is 3, not 15.
To fix, change that to be 15 (after gaining access to the firmware GUI on
the array (telnet or tip)), use "view and edit Scsi channels"
and then select that channel and use "Secondary controller scsi id").
After that is done, reset the controller.
Once the array comes back up, go into "view and edit scsi Drives"
and for each disk, select "scan SCSI drive", then "SCSI channel 3".
When it asks 'Input Fibre ID', enter the ID of the disk (it
shows up in the third column).
After the scanning, you should see the disks showing up as 2(3)
instead of just being on channel 2.
By the way, the sccli will ONLY show channel 2 - you don't get
the (3) on that output.  That is currently an RFE (4950237).
