Satadom switching to read only mode Ubuntu server 20.04

I have several servers which are experiencing seemingly random events where the /boot filesystem is switching to read only mode. My disk layout is:

/dev/sda - ext4 - /boot (63Gb)
/dev/nvme4n1p2 / (890Gb)

These are massively over-specced, I know... I am using the UUID to mount rather than the device names above.

I also have 24 x NVME drives mounted under /data (These are fine) I have tried mount -o remount,rw /boot and get the following error:

# mount -o remount,rw /boot
mount: /boot: cannot remount /dev/sda2 read-write, is write-protected.

I have also tried querying the drive using hdparm and smartctl:

# smartctl --all /dev/sda
smartctl 7.1 2019-12-30 r5022 [x86_64-linux-5.4.0-131-generic] (local build)
Copyright (C) 2002-19, Bruce Allen, Christian Franke, www.smartmontools.org

Short INQUIRY response, skip product id
A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options.

# hdparm  -I /dev/sda

/dev/sda:
 HDIO_DRIVE_CMD(identify) failed: Input/output error

I cannot find a way to trigger this event however the drive has not failed as I can reboot the server and it will mount read/write and continue to work for several weeks. I am able to run an "ls" command on /boot and traverse the directory tree so the data is readable. Device details:

Model Number:       SATADOM-SL 3IE3 V2
Firmware Revision:  S17411i

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
