The root cause is a defect in the SSD firmware that causes the SSD to stop responding. The defect is activated by a specific timing relationship between two commands. New firmware that corrects this is available from Extreme. This FW software is installed on the SSD using the standard Linux “hdparm” utility, that is already bundled with SLX-OS. This can be done remotely and there is no requirement to be physically present on the device. Data on the drive is not affected. The upgrade must be done during a maintenance window as a power cycle is required to activate the new firmware once loaded.
SLX 9540 units should be upgraded with the FW1198 version of the SSD firmware.
Please refer to the procedure document “Diag Smart SSD Controller Firmware Update_v1.5.pdf” to determine if your system requires this FW update. You can find this document in the ZIP file linked below.
