Due to some system constraints, it is not possible to produce a single drive 
firmware package that works on all drives on all Spectrum Virtualize code 
levels. Therefore you will find a selection of different files available for 
use.

You will not need to use all these files to upgrade the drives in the system.


Systems running v8.5.0.0 or higher 
==================================
To upgrade SAS HDD, SAS SSD, NVMe and FCM drives in the system, use the file labelled 
* 8.5.0.0_AND_LATER_ALL_DRIVES

No other drive file will work on these systems.


Systems running releases v8.4.2.x and earlier
==========================================================================
To upgrade NVMe and FCM drives in the system, use the file labelled 
* 8.4.2_AND_EARLIER_NVME_ALL_DRIVES

To upgrade SAS HDD drives in the system, use the file labelled 
* 8.4.2_AND_EARLIER_SAS_HDD_DRIVES

To upgrade SAS SSD drives in the system, use the file labelled 
* 8.4.2_AND_EARLIER_SAS_SSD_DRIVES


This choice of which drive file to use is dependent on the capacity of the 
Drives in the system.  

NOTES:
* The choice of file to use depends on a drive property labelled as 
"Physical Capacity" or "Raw Capacity" in the CLI and the GUI.

* To see the physical/raw capacity in the GUI, use the Pools -> Internal 
Storage panel in the GUI, and use Actions-Customize Columns (with no drive 
selected) to add the "Raw Capacity" or "Physical Capacity" field to the 
table. Different versions of the GUI use different labels, however this is 
the same data.

* For industry standard drives, the physical/raw capacity is the same as the 
capacity of the drive.

* For FlashCore Modules (FCMs) the physical capacity is smaller than the 
reported capacity - due to the internal compression capabilities.
