Solution
Applies to:
Sun Storage Common Array Manager (CAM) - Version: 6.0 to 6.5 - Release: 6.0 to 6.5
Sun Storage 2540 Array - Version: Not Applicable to Not Applicable [Release: NA to NA]
Information in this document applies to any platform.
Goal
Due to the <SunBug 6880697>
Incorrect loop ID returned by the getObjectGraph_MT in a 2540, when a Sun Storage[TM] 2540 is directly connected to a server, Sun StorageTek[TM] Common Array Manager is returning N/A for the loop ID of the corresponding host port.
The intend of this document is to provide you with the procedure to find the effective loop ID for the host ports connected in Direct Attach to the server.
Solution
- Collect a supportdata from the array. Reference <Document 1002514.1> Collecting Support Data for Array Using Sun StorageTek[TM] Common Array Manager.
- Extract the file stateCaptureData.dmp from the supportdata zip file.
- Open this file with your text editor and look for the entry "FunctionId: FC_DUMP Function: fcDump". This will give you two outputs, one for the controller A and the second for the controller B. The loop ID is indicated under the "Our Port ID" column.
Example:
Controller A
FunctionId: FC_DUMP Function: fcDump on controller A
Executing fcDump(0,0,0,0,0,0,0,0,0,0):
fcAll (Tick 0014681055) ==> 01/15/09-01:28:30 (GMT)
1932-A Our Num ::...Exchange Counts...:: Num ..Link Up..
Chip LinkStat Port Port :: :: Link Bad Bad
ID Logi ::Open Total Errors:: Down Char Frame
2-Src Up-Loop ef 2 :: 0 94 33:: 2 0 2
3-Src Down--- 0 0 :: 0 0 0:: 1 0 0
Controller B
FunctionId: FC_DUMP Function: fcDump on controller B
Executing fcDump(0,0,0,0,0,0,0,0,0,0):
fcAll (Tick 0014675460) ==> 01/15/09-01:28:49 (GMT)
1932-B Our Num ::...Exchange Counts...:: Num ..Link Up..
Chip LinkStat Port Port :: :: Link Bad Bad
ID Logi ::Open Total Errors:: Down Char Frame
2-Src Down--- 0 0 :: 0 0 0:: 1 0 0
3-Src Down--- 0 0 :: 0 0 0:: 1 0 0
The host ports are indicated by "Src" (aka Source) and there is two host ports per ST2540:
2-Src
3-Src
In the above example, the first host port from controller A uses the loop ID 0xef, while the other host ports from this controller A or the controller B are not connected (reported as Down---).
