Upgrading the NEM to Allow a SAS-2 Compatible Server Blade in the Chassis |
This appendix provides information on what is required to allow a server module with a SAS-2 RAID Expansion Module (REM) to function in a Sun Blade 6000 Modular System chassis that has SAS-1 NEMs, or SAS-1 NEMs and a Sun Blade 6000 Disk Module (which is a SAS-1 device).
If a server module with a SAS-2 REM is inserted into a Sun Blade 6000 Modular System chassis that has SAS-1 NEMs, or SAS-1 NEMs and Sun Blade 6000 Disk Module, the server’s SAS-2 REM might hang. To prevent this, you need to upgrade the firmware of your SAS-1 NEMs and Sun Blade 6000 Disk Modules to a firmware version that supports SAS-1/SAS-2 coexistence. This upgrade must be done before you insert a SAS-2 server blade into the chassis.
Available SAS-1 NEMs and disk modules that would require this upgrade include Oracle’s:
An example of a SAS-2 server module is the Sun Blade X6270 M2. This server includes a SAS-2 REM. Available SAS-2 REMs include:
Refer to your product documentation to find out if your server blade includes a SAS-2 REM.
For detailed instructions on performing the upgrade, refer to the SAS-1/SAS-2 Compatibility Upgrade Guide for the Sun Blade 6000 Modular System (821-1800) which can be found in:
