Symptoms
SANbox (1G) Qlogic/Sun switch shows additional Sun StorEdge[TM] T3 as 'initiator' rather than 'target' in Segmented Loop (SL) configurations (in addition to the T3 not being seen by the host).
A T3 with a duplicate 'targetid' will show up as 'initiator' when a capture.sparc output is obtained from the switch.

In the following capture.sparc output (from explorer run), port 7 is a T3 device with the same configured targetid as the device already connected to port 1.

7      SL_Port          online         online        logged-in      Initiator
Devices:  0   Address: 0x00

From the new T3, the following 'port list' output shows the targetid.

 port list
 port   targetid   addr_type   status   host   wwn
u1p1      1        hard       online   sun    50020f2300001234

targetid 1 = al_pa 0xe8 (which is already used by port 1).



Resolution
Because al_pa's are unique, the new T3 could not obtain the al_pa it was configured to use. Since it was not configured to obtain a soft address in this situation, the T3 couldn't join the loop. The switch shows this state as 'initiator' rather than the usual 'target'.

The resolution is to change the targetid (to an unused value) on the new T3 and issue a reset command.
example:

 port set u1p1 targetid 5
reset


Additional Information
Although the need for unique targetid's is well documented in the T3 manuals, the symptom of 'initiator' on a SL is not.
