SAS Address NOT programmed on controller in slot (1)
Initializing...
ERROR! Adapter Malfunctioning!

Changes

Recent physical disk configuration changes connected with a possible power problem might lead to this outcome. This can also be noticed when the SAS controller is flashed using an improper address.

Cause

When the controller is not properly flashed, the manufacturing area which contains the WWN will get erased. Without this number, the controller will malfunction.

Solution

Next step to be taken is for the SAS address to be written back on the card itself. For this, the bellow tool and details are required.

1. The SAS card WWN number - the SAS address (WWN) is available on the sticker on the module. This should be in the form of 50062b000000000 or 0x50062b000000000.

2. To interrogate and to write back the SAS address, we will need the sasflash (sas2flash) utility, on a bootable medium. The utility is usually bundled with the Tools and Drivers DVD for the system or with the general firmware package.

All firmware packages are available via Firmware Downloads and Release History for Sun Systems. Alternatively, the utility can be downloaded from the cards manufacturer site.

Using the above data and tool, the next step is for the address to be written back, This is achived using the sasflash -o -sasadd <WWN> command; the WWN to be used is the one previously found on the sticker.

sasflash -o -sasadd 50062b000000000

Before any steps are taken, should always ensure that an up to date backup of the system is available.

Both
sasflash -o -sasadd 50062b000000000
sasflash -o -sasadd 0x50062b000000000

are valid formats for the address to be written back to the card.

Use the sasflash -o -listsasadd command to get the current SAS address. After the above steps have been completed, a cold reboot is recommended.
