Fiber Channel Error

Having a problem with the Fiber Channel on our Xserve RAID. The Admin Utility says that Fiber Link 1 is Down (and it's red), but everything is properly connected, I have restarted several times, unplugged and plugged back in, done a few upgrades to the firmware and it still says it's down.
Any ideas?
Thanks.

I swapped the Fibre cables, controller and reseated the card in the mac. Still nothing. I noticed under the Hardware Overview that there is not even an option for Fibre Channel. Is this due to the system running 10.3.9?
Thanks.

Getting end-of-file on communication channel error on this query

Hi guys,
I'm getting the end-of-file on communcation channel error when running the following query in SQL PLUS, If run it in a stored procedure called through code of JDBC, it gave "no more data to read from socket" error. Any idea what went wrong? kind of frustrated now. We are using the Oralce 9.0.1.4.0, which suppose to fix some sdo_uion and sdo_buffer bugs. Thanks a lot!!
select SDO_GEOM.SDO_BUFFER((SELECT SDO_AGGR_UNION(MDSYS.SDOAGGRTYPE(GEOLOC, 0.011119487)) FROM GEOTEL_SOURCE where MSA='5000' and COMPANY_NAME ='AMERICAN FIBER SYSTEMS'),1.0,5,'unit=MILE arc_tolerance=0.05') from GEOTEL_SOURCE a where a.MI_PRINX = 1;

Hi Daniel,
Just tried the 9.2.0.2 patch, seems to work better now. At least I don't get the end-of-file on communication channel error. But how about the speed thing? I isolated the problem, and find out that sdo_aggr_union is taking too long to finish( 1 Hour!!! for 2300 lines with the same city. Any clue to optimize it, I tried some hint like /*+ordered*/ No_Merge and something like that, does not improve though. Thanks!

NFS Commnication channel errors for deleting and placing

Hi All,
I was trying File to file scenario.
I am picking the file from App server(AL11) using NFS Adapter and the processing Mode is Delete
In comm channel monitor it showing an error as
Sender channel error:
Error: File '/staging/INTERFACE/SAP/ca/kar370.txt' - deleting after processing failed
Same way while placing the file
Receiver channel error:
Error: Message processing failed: FileNotFoundException: /staging/INTERFACE/SAP/ca/test120110906-122051-980.txt (Permission denied)
Whether i dont have the permission to delete and place the file from and to the App server(AL11)?
What is the procedure in order to make it possible.
Thanks
Sai

Hi All,
Thanks to every one.
The problem is solved ,
Basis Guy has given the permissions, and i am able to place and delete the files .
Thanks

XI Communication Channel Error Explanation

Hi All,
Does anyone happen to know :-
1) Is it possible to use CCMS to email the errors coming from a communication channel error Explanation field
2) Are these messages stored in a table I can check
The reason I need to know this is because we sometimes encounter an error such as "Conversion of file content to XML failed at position 838: java.lang.Exception: ERROR converting document line no. 839 according to structure 'XXX_XXX_XXX':java.lang.Exception: ERROR in configuration / structure 'XXX_XXX_XXX.': More elements in file csv structure than field names specified!
This tells us exactly where the error occurred but using Communication Channel Monitoring the error message only remains for a little while before the polling messages remove it from the display. Since the process runs early hours of the morning we never get to see these messages.
Any help appreciated.
Thanks
Craig

Hi Raquel,
Let me try to clear out some things in this thread . First of all you do your alert configuration which you say you have already done. Thats good . Now you ask that you want only to monitor the communication channels and you want specific guide . Here is the specific guide.
If you have configured alerts you will know that when you create an alert rule you have the option to choose radio button where did the error occur it could be no restriction , integration engine or adapter engine. You need to choose adapter engine.
Now whenever the colour of the lights change to red. You will get your alerts.

What are the host network requirements for a 2012 R2 failover cluster using fiber channel?

I've seen comments on here regarding how the heartbeat signal isn't really required anymore - is that true? We started using Hyper-V in its infancy and have upgraded gleefully every step of the way. With 2012 R2, we also upgraded from 1gb iSCSI
to 8GB Fiber Channel. Currently, I have three NICs in use on each host. One for "No cluster communication" on it's own VLAN. Another for "Allow cluster network communication on this network" but NOT allowing clients, on
a different VLAN. And lastly the public network which allows cluster comms and clients on it (public VLAN).
Is it still necessary to have all three of these NICs in use? If the heartbeat isn't necessary any more, is there any reason to not have two public IPs and do away with the rest of the network? (two for fault tolerance) Does Live Migration
still use Ethernet if FC is available? I wasn't sure what all has changed with these requirements since Hyper-V first came out.
If it matters, we have 5 servers w/160GB RAM, 8 NICs, dual HBAs connected to redundant FC switches, going to two SANs. We're running around 30 VMs right now.
Can someone share their knowledge with me regarding the proper setup for my environment? Many Thanks!

Hi,
You can setup cluster with a single network but that leaves you with single point of failure on the Networking front, it is still recommended to have a heartbeat network.
Live migration would still happen though Ethernet, it has nothing to do with FC. Don't get confused, you had iSCSI for storage which used one of your VLAN and now you have FC for your storage.
Your hardware specs looks good. You can set up the following networks -
1. Public Network - Team two or more NICs (based on bandwidth aggregation)
2. Heartbeat Network - Don't use teamed Adaptor
3. Live Migration - Team two or more NICs (based on bandwidth aggregation)
Plan properly and draw guidelines to visualize and to remove single point of failure at all points.
Feel free to ask if you have some more queries.

ORA-03113: end-of-file on communication channel ERROR

After applying Database patch 3095277 to my 9.2.0.1.0 installation
in order to update it to 9.2.0.4.0,I'm getting ORA-03113: end-of-file on communication channel
ERRORS when attempting various tasks. This is a local installation running on a Windows XP Workstation.
I've even tried creating a new test database but the result is the same.
The reason for moving up to 9.2.0.4.0 is so I can start using Advanced Queuing, which I understand had problems in earlier releases.
However before the update I could at least create the JMS queue tables without ERROR whereas now I get the following errors when attempting to create a queue table in SQL Plus from within Enterprise Manager Console.
SQL*Plus: Release 9.2.0.4.0 - Production on Thu Sep 18 08:20:08 2003

BEGIN SYS.DBMS_AQADM.CREATE_QUEUE(Queue_name=> 'JMSQUE',queue_table=> 'JMSQTBL'); END;
ERROR at line 1:

I would be grateful of any pointers as to how to resolve this problem.

Gary.

Chris, Thanks for the suggestion,
I took a look in the trace log and found the following entries that point to a ORA-00600 as you mentioned earlier.
This is only a test database so there's no great loss if
I have to re create it, but in saying that I did create a new test02 from scratch and had the same problem.
Is it posible something went wrong when applying the 9.2.0.4.0 patch ?.
Regards
Gary.

Receiver JDBC Channel Error : Incorrect syntax near 'OR'

hi,
we are facing the below error at the receiver communication channel:
Error while parsing or executing XML-SQL document: Error processing request in sax parser: Error when executing statement for table/stored proc. 'table' (structure 'statement'): com.microsoft.sqlserver.jdbc.SQLServerException: Incorrect syntax near 'OR'.
When we again reprocess the message,it shows the exact error at the channel.
Any ideas why the first error shows up?

Hi, Anu
The most probable it's that your target XML it's not correct because it haven't a correct format.
Please, check your target XML and see

Communication Channel error (Device busy)

HI all,
i have a problem with sender communication channel (CC) (type file) on PI 7.1
The CC has follow error:
Delivering the message to the application using connection File_http://sap.com/xi/XI/System failed, due to: com.sap.engine.interfaces.messaging.api.exception.MessagingException: java.io.FileNotFoundException: /IFR_PI/prd/out/TYPEB/SEDE_PV/PV_ART/VARGPV_I003 (Device busy).
Anyone can help me to understand this error?
Thanks in advance
PM

Hi,
      The file size is a drawback of file adapter.
      Check the note Note 821267 - FAQ: XI 3.0 / PI 7.0/ PI 7.1 File Adapter
     See point 14. Memory Requirements
Indeed the error is IO Error and it is because the Adapter engine was not able to send the message to Integration server. But it happens due to memory/heap size issues.
Look at these thread, they are having the same problem. Please try the remedy measures suggested by them

JDBC to JDBC Scenario - Communications Channel Error

I am following the published JDBC to JDBC Scenario:
https://www.sdn.sap.com/irj/sdn/wiki?path=/display/xi/step-by-step+guides
I am a 3rd Party Vendor, and I'm using NX7: SAP Exchange Infrastructure. My goal is to have a JDBC Sender that sends MS Access data from my PC to NX7, and have a JDBC Receiver that receives MS Access data, and map the data from one database to the other via XI per the scenario, with both databases on my PC.
I set up the NX7 SAP XI per the scenario, but I'm getting an error on the NX7 Communications Channel:
Error during database connection to the database URL 'jdbc:odbc:Driver={Microsoft Access Driver(.mdb)};DBQ=//204.245.44.232/C:/Documents and Settings/All Users/Documents/XI_FILES/SENDER/STUDENT_Database.mdb' using the JDBC driver 'sun.jdbc.odbc.JdbcOdbcDriver': 'com.sap.aii.adapter.jdbc.sql.DriverManagerException: Cannot establish connection to URL 'jdbc:odbc:Driver={Microsoft Access Driver(.mdb)};DBQ=//204.245.44.232/C:/Documents and Settings/All Users/Documents/XI_FILES/SENDER/STUDENT_Database.mdb': SQLException: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified'
The data source is in
C:/Documents and Settings/All Users/Documents/XI_FILES/SENDER/STUDENT_Database.mdb on my PC and it is a shared folder. My PC IP 204.245.44.232 is a public IP address. It should be using the JDBC-ODBC bridge driver in the JDK.
Why am I getting the error?
Thanks,
Ed Culnane

Hi
Connection Parameters are of given below check
Transport Protocol: JDBC 2.0
Message Protocol: XML SQL Format
Adapter Engine: Integration Server
JDBC Driver: jdbc.odbc.JdbcOdbcDriver
Connection: jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=//xiserver/xitemp/db/TestDB.mdb
5) In my case there is no userid and password required, but if you have userid and password, then the parameter for Connection becomes,
jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=//xiserver/xitemp/db/TestDB.mdb;Uid=yourid;Pwd=yourpwd;
Well ms access file should be in the XI Server path or it should be able to accessed by the XI
Try this above option of keeping u r file in the XI Server path instead of the local

External Fiber Channel Raid options for New Xserve besides Promise V-Trak

I was wondering if anyone out there knows if there is an alternate option for a External Raid that can be hooked up via 4gb Fiber Channel to my new Xserve. I am really looking for a more cost efficient one than the 12K Promise set up from Apple. My Technology vendor was telling me that you have to use the Promise Raid as it is the only one that a Xserve will control due to Apple's licensing of its drivers etc. for its Fiber channel. Something tells me that this is not true.
Anyone have any recomendations for a Fiber channel Raid solution in the 6K dollar range?
thanks,
Dan

Find another vendor. Anyone that tells you the Promise is the only RAID that will work clearly doesn't understand the market.
As for recommendations, you need to include some idea of capacity, either usable or raw. I can find you a lot of options for $6K if you want a 100GB of data. Not so many if you want 100TB.

XSERV RAID FIBER CHANNEl

We have XSERV RAID MODEL A1009 with 4 Hard disk RAID 5.
Now I have installed CISCO 1000Base SX Module in 3 COM Switch & other same Module in XSERVER RAID. Now XSERVE RAID & switcted with Transeiver cable. Now I check RAID ADMIN TOOL FIber Channel Option the links shows down.
Let me know what is solution. Please also let me know how can I know that fiber link is up if any way.

Finisar makes a nice SFP to LC transceiver (available on the Apple Store for $99.95 for 2 Gbit and $119.95 for 4 Gbit) that you can use in the Xserve to allow it to accept LC optical cables. You'll need 2 of these, and then you can hook up LC optical cables.
I'll echo the other post -- be aware those ports are for fibre channel communication ONLY. You must hook it to a fibre channel card (HBA) in a host, or to a fibre switch (i.e. Cisco MDX 9000 series). You cannot hook up a network connection to those ports -- Xserve RAID provides data ONLY over fibre channel, it is not a NAS device. You must connect it to a host which can re-share the data over Ethernet, for example Xserve RAID with OS X Server which can reshare using AFP, SMB/CIFS, NFS, FTP, DAV, and more.

Kernel panic when connecting fiber channel

I recently inherited an Xserve RAID. I have an LSI fiberchannel card in a G4 running 10.5.5.
Anyway, I updated the firmware to version 1.5 and now everytime I connect the fiber channel cable I get a Kernel panic instantly and have to force power down.
I've tried 3 different cables on and every port on the mac and the xserve and get the same result.
any idea what's going on?

Well, i just upgrade to 10.8 and its solved the question.

IP over fiber channel

Idle curiosity question:
Does anyone know whether or not Netware or OES supports IP over fiber
channel?

If you dont use 802.1q (vlan):
You must create another fcip interface and use existing fcip profile, but when configuring peer-info
address you should use another ip address.
fcip profile 1
ip addres 1.1.1.1
exit
int fcip 1
use profile 1
peer-info ipaddress 1.1.1.2
int fcip 1
use profile 1
peer-info ipaddress 1.1.1.3

Use of Fiber Channel in Boot Camp with Windows XP

Hi All,
I am looking at getting a Mac Pro for a project that requires I use Windows XP under boot camp and wanted to know if there were any problems accessing a RAID array via the standard 4GB Fiber Channel adapter available through apple. I don't need to boot off this drive, just access data on it. Not a lot of information on the official apple support pages...
Thanks!

Yes, XP will be able to detect the expansion card if you download the appropriate drivers online. When bootcamp was first starting... this article circulated http://docs.info.apple.com/article.html?artnum=305401... summary, you should remove the fiber channel card before bootcamping. Since then the software has gone through the proper modifications that you can just plug the card in, boot into windows, and download the LSi driver for XP.
So you'll have no problem setting this up.
Cheers
Ron
