Goal
--- Purpose ---


The purpose of this document is to ensure that communication with Sun Storage J4000 and
F5100 Series arrays is operating properly using In Band management. In Band management is
defined as any user interface commands passed to the array to either monitor the status
of or change the configuration of a storage array by sending commands over the same path
that is used for data.
Solution

 
Steps to Follow:

Please validate that each troubleshooting step below is true for your environment. 
The steps will provide instructions or a link to a document, for validating the step 
and taking corrective action as necessary. The steps are ordered in the most appropriate 
sequence to isolate the issue and identify the proper resolution. Please do not skip a step.

1. Identify the type of In-Band Management Layout you have.There are two basic layouts to this management infrastructure.
The types below will be listed in terms of Sun Storage Common Array Manager (CAM).
Type 1:

CAM on same host as data host --- Data Path to Array to manage--->Physical connection to Array
In this case JBOD management host and Data Host are the same.
Includes Full CAM installation.
Type 2:
CAM Server ----TCP/IP---->
Data Host with In-Band Proxy software ---Data Path to Array to manage--->Physical connection to Array

The CAM Server is where you use the management application to manage the disk array to present to the host for data access.  
In Band Proxy Host is the location of the Proxy Software.
 * If you have a Type 1 Layout, open a shell or command prompt (Windows) 
   on your CAM Server, and continue to Step 6.
 * If you have a Type 2 Layout, open a shell or command prompt on your 
   CAM Server, continue to Step 2.
2. Telnet to port 8653 on the In-Band Proxy Host:
telnet  8653
where  is the IP-address of the In-Band Proxy Host (CAM Data Host).
-If the result is connection refused, go to Step 4.
-If the connection is established go to Step 5.
-If the connection states node name or service name not known, go to Step 3.
3.Use ping to Validate that the Management Server can route IP traffic to the In-Band Proxy Host.
 -If ping fails, you have a network routing problem, or your IP address is incorrect.  
Once ping succeeds, try to:
telnet  8653
-If ping succeeds, and the attempt to telnet above continues to fail, you will need to log 
into the In-Band Proxy Host (the host connected to the array) as a user 
with Administrative privileges, then:
telnet 127.0.0.1 8653
* If the result is connection refused, go to Step 4.
* If the connection is established, this indicates that the in-band agent is running  
on the In-Band Proxy Host, but there is some piece of network software 
preventing the CAM Server from connecting on that port.  This typically indicates 
that there is some type of  firewall software preventing this connection.  
Once the port traffic is opened repeat Step 2.
4. Check that the In-Band Proxy Agent is Listening on the network for port 8653:
For Solaris and Linux:
netstat -an | grep 8653
For Windows:
netstat -an  /p
Use the /p switch to pause the output to review for port 8653
    * If the port is not listening, go to Step 5.
    * If the port is listening, go to Step 6.
5. Enable remote control on the CAM Data Host, and create a password:
This will verify the CAM Data host has remote control access enabled.
For UNIX (Solaris and Linux):
#/opt/SUNWsefms/sbin/proxycfg enable 
sh-3.00# /opt/SUNWsefms/sbin/proxycfg enable
Agent configuration saved.
Hostname  : v4u-4800a-doma-fll03
Hostid    : 8307fcf0
IP        : 10.2.22.146
Frequency : 5
Active    : Y
You will see the following on a Solaris 10 system:
svc:/system/fmservice:default temporarily disabled.
svc:/system/fmservice:default enabled.
Restarting Sun Java(TM) Web Console Version 3.1 ...
The console is running
-If the error: "directory specified doesn't exist" is returned from fmservice, go to Step 7.
-If not enabled go to Step 6.
-If enabled go to Step 8.
6. Determine if we can see the SES (SCSI Enclosure Services) device for the array:

For Solaris:
prtpicl -v -c scsi
For Linux:
grep -i model /proc/scsi/scsi
For Windows:
Start->Administrative Tools->Computer Management->Device Manager
Look under Other Devices (the yellow "?") OR System Devices
For example:
prtpicl -v -c scsi|grep 
 :inquiry-product-id
 :inquiry-product-id    Storage J4500
 :inquiry-product-id    Storage J4500
 :inquiry-product-id    Storage F5100

If you can see the SES device, go to Step 8. If the SES device is not detected, 
reseat the SAS cables connected to the HBA and array and recheck.
If SES device is still not detected go to Step 12
If SES device is detected go to Step 8.
7. Validate that the In-Band Agent CAM software is installed on the CAM Data and Management Host:

For Solaris:
pkginfo -l i SUNWsefms
   PKGINST:  SUNWsefms
   NAME:  Sun StorageTek(TM) Fault Management Services (Core)
   CATEGORY:  application
   ARCH:  all
   VERSION:  6.6.0,REV=2010.02.18.07.17.33
   BASEDIR:  /opt
   VENDOR:  Sun Microsystems, Inc.
   PSTAMP:  20100218-1917.11
   INSTDATE:  May 14 2010 14:16
   HOTLINE:  Please contact your local service provider
   STATUS:  completely installed
   FILES:      134 installed pathnames
                 6 shared pathnames
                25 directories
                21 executables
             15184 blocks used (approx)

For Linux:
rpm -qa | grep SUNWsefms
For Windows:
Start->Control Panel->Add/Remove Programs
If not installed, install latest version and then go to Step 4.
If already installed, go to Step 8.
8. Verify the FMS service status:
Check the status of FMS:
Solaris 10: 
svcs svc:/system/fmservice:default
Solaris 8,9: 
/opt/SUNWsefms/sbin/fmservice.sh status
Linux: 
/opt/sun/cam/private/fms/sbin/fmservice.sh status
Windows: 
Use Start->control panel->Administrative Tools->Services to check status of Sun_STK_FMS
Verify that FMS status is online.
If FMS services is running, go to Step 11.
If FMS services is not running, go to Step 9.

9.  Initialize CAM FMS Services and validate it is started:
For Solaris 10: 
svcadm restart svc:/system/fmservice:default
For Solaris 8,9: 
/opt/SUNWsefms/sbin/fmservice.sh restart
For Linux:
/opt/sun/cam/private/fms/sbin/fmservice.sh restart
Windows: 
Use Start->control panel->Administrative Tools->Services
Use the process in Step 8 to verify FMS  is running.

10. Run agent and re-register array:
In the CAM BUI: 
-At the General Health Monitoring Setup screen,
select the Run Agent button specifying the correct Array type.
-Then re-register (unregister first if array shows up):
At the Storage System Summary screen select the Register button from 
the left side of the table.
If problem is not resolved then go to Step 12.
11: Check that the version of CAM is at least at 6.5 Revision:
Refer to Step 7 instructions for checking the SUNWsefms software package.
If below  version 6.5, upgrade CAM baseline and then go to Step 10. 
If at version 6.5 or later, go to Step 12.

12. Data Collection:
Please collect and compile the following information and engage technical support:
    * The In-Band Layout Type from Step 1.
    * The IP addresses or at least the host names for reference identified in Step 1.
    * The Results of Step 2 for type 2.
    * The Results of Step 5 for type 2
    * The output of netstat -an for type 2.
    * The output showing the SES device or a lack of one from Step 6.
    * The Results of Step 8.
    * The output result of Step 11.
    * The host OS for the In-Band Proxy Host.
    * The host OS for the Management Server.
    * The array model that requires management.
