In cases where a replacement drive arrives with newer code, but to maintain consistency across an environment an older version of code is required to be installed prior to deployment into a customer environment, the prior versions of code will not load.

Any T10000A drive running 1.34.108 code or later is impacted by this issue.

When loading older microcode through the VOP tool, the tool will appear to hang.  When VOP is reset, the original code will still remain on the drive.  There are no other indications beyond the failure to load the older versions of code.

Newer versions of firmware are digitally signed and checks for this signature when loading code.  It will not load previous versions of firmware that are not digitally signed.

To load a down level code, first load the 1.34.108 Bridge Code, then load the own level code.  This Bridge Code can be installed from the CRC via the below URL:

The features of the Bridge Code are:

1) The bridge code is digitally signed so it can be loaded by firmware that checks the
   digital signature (134.108 or later code).
2) The bridge code does not check the digital signature of any firmware it loads, so it
   can load down level unsigned firmware (133.107 or earlier code).
3) The bridge code rejects reads and writes with FSC 344C.
4) The bridge code will not load a release firmware level below 1.31.103 onto a drive
   that does not have encrypting hardware and it will not load released firmware
   below 1.32.203 onto a drive that does have encrypting hardware.
5) The encryption state of the drive will persist through the load.
6) If encryption is enabled and the drive is not reset, the first IPL of the bridge code
   will perform a key reset on the drive. The key reset causes the drive to IPL again.
   The reset will erase the device keys and will allow a drive to be used with KMS 1.0.
7) The bridge code is based on 1.34.108 and will display RB.34.108.

Note: This Bridge Code can only be obtained from the CRC as described above.
