The Storage J4500 array enclosure contains upgradable firmware. You may want to upgrade the enclosure firmware to:
Install the latest bug fixes and performance enhancements
Add new features and capabilities as they become available
The Sun Common Array Management (CAM) software provides firmware upgrade capabilities for the J4500 array connected to any supported HBA. For more information on using the CAM software, see the Sun Storage J4500 Array System Overview (820-3163).
The J4500 array contains two SAS fabrics (A and B). Each fabric has its own set of SAS expanders. The firmware upgrade process is only performed on the fabric with the active SAS link to the HBA. When upgrading enclosure firmware, Sun recommends that you upgrade firmware on both SAS fabrics to ensure they are at the same revision level.
This will require you to take the following steps:
Using CAM, perform the upgrade on the enclosure's primary SAS fabric.
Then, at a convenient time, move the SAS cable to the enclosure's secondary SAS fabric.
When performing this action, allow time between the removal of the link from the primary fabric and the reconnection to the secondary fabric for your HBA to recover from the lost and then re-established SAS link. Depending on the HBA, this can take up to 2 minutes each time the link state is changed.
Using CAM, perform the upgrade on the enclosure's secondary SAS fabric.
