Hi. I have a Sun StorageTek 6140 array with 32 Sun ST3300007FC drives. Sun rebrands them and seems to have changed the model number on the drives so the array limits recognition to the Sun drives. I've added a new shelf for an additional 16 Seagate ST3300007FC drives and went the cheap route with HP-rebranded ST3300007FC drives. Of course, the array doesn't recognize the drives. The latest Sun firmware for these drives is 055A. Sun ships the firmware for these drives as a D_ST330000FSUN300G_055A.dlp file. I think the format of this file is similar to what HP uses with a .df extension (http://hardforum.com/showthread.php?t=1660270).

Is there a tool I could use to change the model number of this drive to "ST330000FSUN300G"? I think if I do this, I can use the array software to replace the firmware. The big issue is getting the drive recognized and I think the solution to this is changing the model number.

Could you provide a link to the firmware? I probably won't be able to help you, but I'd like to examine the structure of the update. FWIW, I've done similar work for Seagate, WD, and Samsung SATA drives.

The firmware structure doesn't look like any Seagate examples that I've analysed. :-( The MCU appears to be based on an Intel 8096 core rather than ARM. Other update packages are comprised of several modules, including the PCB ROM and some SA modules, typically overlays. The latter are located on the platters. Unfortunately I don't have a resource dump for comparison purposes, so I'm finding it difficult to identify the individual components in the DLP file. Normally it would be a bad idea to update a retail drive with OEM firmware, because you cannot be certain whether the updated modules are compatible with the existing ones. However, knowing which parts are targeted by the update may help to minimise the risk.

I notice that the code contains the text string, "SER NUM MISMATCH". This would suggest that the ROM on the PCB may be modular, ie it may contain a mix of code plus unique, drive specific data. If so, then that would make it even harder to extract the ROM sections from the DLP file.

That said, there is sometimes a method, at least in SATA drives, where an update may be "forcibly" applied. However, such a method would depend on the tool that is used to apply the update (eg SeaFlash or SeaTools Enterprise version, or something else). Was Sun's package shipped with any such tool, or do you have a link to a Dell or HP update package for the same drive?

Unfortunately, chances of this approach to work are slim to none.

With the help of someone on the #openindiana IRC list, I was able to separate the Seagate firmware from the Sun D_ST330000FSUN300G_055A.dlp firmware file. I tried to flash the firmware to an HP-branded Seagate ST3300007FC drive but was unsuccessful:

I bought 11 of the drives. I'm shipping them back today. Let me try some more of them.

Does the sense data I posted indicate a problem with the drives? They were suppose to be new drives, though HP-branded.

Seagate Entetprise HDDs have firmware OEM lock. No way to change firmware types safely

We have played with Seagate drives some time ago, converting few of them from generic to OEM ones and vice versa, changed between different OEMs as well. But the process is a real PITA and it's not always possible to replace the firmware, as even modules structure can be different, so it is quite easy to put the drive into a coma.

SENSE 5-24-00 is from the "invalid parameter" series.
Firmware and loader contain unique ids, which are obviously different for HP and Sun, so just uploading the firmware isn't an option.

Moreover, even if you'll find a rather tricky way to patch the loader, there's another level of protection, which will prevent the upload. Besides all that drive lock mechanism adds some extra fun to the process to make sure that after failure researcher will have to dig through the SA manually to revive the drive.
