Are MZ-ILS3T80 PM1633 good?

[DaAwesomeP]

I'm looking at multiple sellers of MZ-ILS3T80 PM1633 SAS SSDs. A few of them explicitly say 512B and others don't. Do these have any known longevity or other issues to be aware of? These are for light home use, so I'm not too worried about them being used. Things I am unsure of:

• Can they be realigned to 512B or do I need to be careful of that?
• Is there some 32K hour bug? Is there a date code that marks them as safe? Is the firmware worth flashing?
• Anything else?

Models I am seeing: MZILS3T8HCJM-000C4, MZILS3T8HCJM-000C3 (I think they are EMC ones? How can you tell?),

I have scoured the forum but am seeing mixed answers to these.

Thanks!
Perry

Yes, PM1633 are affected by the 32k hours bug.
Dell EMC identified them as vulnerable in a service release of their VNX systems.

Quoting Dell:
„MZILS1T9HCHP | MZILS3T8HCJM | MZILS480HCGR | MZILS960HCHP sentenced to death on CQPG, CQPH -> fixed on CQPJ

Reformatting from 520 to 512 (and even to 4K) is possible (did this several times with NetApp and Dell EMC branded ones).

Thanks for your response! It sounds like you have rescued a few of these before they die. Would you confidently buy them again (assuming they have not yet hit 32k hours)? Or should I find another SAS SSD model? They do also seem a bit power hungry.

Just to confirm: I would reflash the MZILS3T8HCJM with the CQPJ firmware?

Another quick question: I don't see an EMC logo, but I do see an "EMC P/N" label. Is that the only signifier they are Dell/EMC?

At this point do we have a list of all SSD affected by Hour Bugs?

Seems a # of intels and Samsungs etc are affected.

Unfortunately not, lost my sheet I started in the past. At least several SanDisk from that area are known to be affected as well. Mostly HP ones.

Depends on the use case. Today I surely would go for one or two 30 TB NVME instead 12 4TB SAS. When I bought them SAS was much cheaper than NVME for ~30TB.

Only flash if the ones you get are EMC ones, from their Storage lines. Means: check which firmware they do have and compare with affected versions. In addition to those EMC ones Dell sold 1633 with different firmware for their Poweredge series, firmware for those are easily available

Another quick question: I don't see an EMC logo, but I do see an "EMC P/N" label. Is that the only signifier they are Dell/EMC?

Depends, as written above there exists two versions of PM1633 with Dell EMC branding/firmware. One for the former EMC storage series’s, one for PowerEdge servers.

I read through this post but am still not able to determine what utility I should download to update the firmware for these drives. The drive in question:


This appears to be an EMC drive, and I have seen the post with the firmware update and downloaded it. It is a RAW file.
Assuming I am able to format the drive from 520 to 512 sector size, what utility would I use to update the firmware?

I have looked on Dell's website to no avail, and I have read that samsung Magician would not work since the drive is EMC branded.
What would be the next step? I have access to a DELL R740xd running ubuntu with rear flex bays that support SAS3 drives. Would running an update from a lifecycle controller be a possibility or would I need the Dell Storage Center OS?

Is it possible to use sg3_utils to update the firmware?

I have read the SSD resurrection post eluded to in this thread but I am still unsure how to proceed.

Any help would be most appreciated.

 

[mrpasc]

sg3_utils is the way.

 

[hindutool]

Thank you so much! I take it the command is as follows (from this thread)?

sg_write_buffer -m dmc_offs_save -I FMDELMZILS3T8HCJMCQPJ_NS /dev/sg14

 

[hindutool]

Sorry I meant to write:

sg_write_buffer -m dmc_offs_save -I FMDELMZILS3T8HCJMCQPJ_NS /dev/sgX

Sorry I meant to write:

sg_write_buffer -m dmc_offs_save -I FMDELMZILS3T8HCJMCQPJ_NS /dev/sgX

Did it work?

I cannot get the MegaRAID 9560-16i to access the drive. It merely lists it as unsupported. I cannot make it unconfigured Good/Bad or anything else. It will only allow me to start/stop locate or remove the drive. Firmware on the RAID controller is up to date. Will be reaching out to broadcom support. I have a 9460-16i and a 9380-8i8e and a 9361-16i that I am going to try it on as well. If anyone has any ideas I am open to it.

Does it allow you to put the drives in JBOD mode?

 

[hindutool]

No. For that to happen the drives need to be listed as unconfigured good first, and it does not list that as an option. Only locate start, locate stop, sanitize, and remove. Moreover, when I click on the sanitize option I receive an error. This occurs both in LSA, and in the EFI bios. I'm kinda stuck here.

 

[hindutool]

No dice guys. Broadcom and samsung were of no help. I had to ship the drive back. If anyone experiences this problem and has figured a way around it I'm all ears.
