=Comment: #0=================================================
Lucio Jose Herculano Correia <luciojhc.com> - 
After installing RHEL6 Snap13 on standalone P6 HV4, I got these error messages during first boot. It
seems to happen on every boot.

Hi Wayne,

we could we use some of your scsi expertise. If I'm looking at the log correct drivers/scsi/ses.c sees 3 enclosures

ses 0:4:18:0: Attached Enclosure device
ses 0:6:18:0: Attached Enclosure device
ses 0:8:0:0: Attached Enclosure device

and when Hien physically looked at this system there was 1 enclosure with 8 disks. ideas on why ses.c thinks there are 3 enclosures?

The first thing that needs to be done is to upgrade firmware.

I've upgraded the firmware on the Cadet-X adapter.  It was quite old.

The first two enclosure devices are part of the internal Lahaina enclosure.  The current firmware level is this:
A1700DE2.0001 (04-18-2008)  Bring up Code.

It needs to be upgraded to A1700DE2.0008, but I need someone to verify the following:

Microcode Update/Download directions from 0001 to 0008

??         Make sure you do NOT have any cable attached to the back of Lahaina during this code update from 0001 to 0008. ( I am talking about the RED cable that goes from Lahaina to the back of the system )

Hien, could you verify that this cable is not attached?  If it is, could you disconnect it so that I can do the upgrade?

Also, would someone please post the HMC information for this system?

Steve,

To answer your question, the three enclosure devices are expected and are part of the internal SAS architecture.

http://ausgsa.ibm.com/~jschwarz/SAS%20Presentation/SAS%20on%20HV8%20&%20HV4.htm

The SAS addressing for Lahaina shows the three ses devices.

http://ausgsa.ibm.com/~jschwarz/SAS%20Presentation/SAS%20on%20HV8%20&%20HV4.htm#SAS_Addressing

In this case 0:4:18:0 and 0:6:18:0 are the 1st and 2nd ses devices.  0:0:8:0 is the virtual ses device.
Comment 12 Steve Best 2011-04-15 09:46:57 UTC 
closing upgrading the firmware fixed this issue
