Crucial MX500 new firmware rev M3CR032 causes RAID controller failures

dell-perchardware-raid

I've been using Crucial MX500 disks in Dell hardware for a while now (non-server class disk, I know, I know… we're cheap) with firmware M3CR023. But the latest batch arrives with revision M3CR032 — this revision can be used in a RAID config (I'm using a PERC H730 or H740) but the RAID controller fails every instance of the drive on warm reboot.

Cold boots seem to re-initialize the drive correctly, and it can then be imported as a 'foreign' config, but warm reboots lead to all disks failing.

Crucial support has been no use whatsoever, and I've been unable to downgrade the firmware using either their Storage Executive software on windows or by unpacking their "bootable ISO" and running the Micro msecli utility under linux. Has anyone else run into this problem with that specific firmware?

There is a new firmware M3CR033 to fix RAID issues:

M3CR033 includes the following changes:

  • Fixed SATA protocol error that causes start-up failure on certain data center RAID systems
  • Improved boot time after unexpected power loss
  • Fixed Read DMA command abort after an interrupted Secure Erase

So update the firmware ad look if it fixed the issue.
