sandisk 1.6T的ssd需要更新固件到a318

FS System: SanDisk 1.6TB SSD (Solid State Disk) Drives Have Latency Issues in Clustered Environments (Doc ID 2044905.1)

 SSD Drives will either go offline and then comeback on line within 60 seconds or fail altogether.  Either of these symptoms will likely generate log bundles with the following events:

ENCLOSURE_DRIVE_STATE_CHANGE
RAID_EVENT_SAVE_TRACE
The issue is only seen with SanDisk 1.6TB SSD Drives in an FS1-2 Flash Storage System in a clustered environment under a heavy load. 

SOLUTION

The problem is fixed in drive firmware version A318.  This drive firmware is part of the R6,2.9 (or later) version of the FS1-2 software.  Updating drive firmware is a disruptive upgrade which requires an outage.
