Hi,
First of all I would like to mention that I have searched the previous 2 days like almost all of the solutions I could find in google but I could not find any solution. I hope I will find here. I do not want to loose my ssd!!
The story is that this ssd that I want to erase and reuse it. It was pulled from an older vSAN for a reason I can not remember it was in error state then.
So I am trying to erase from vSphere no luck I have attached a picture. I have connected with putty, trying with the partedUtil - no lack. It seems that the ssd is being configured as read only. I do not know how to change it. The vSAN that was mounted before does not exist now.
Ι have tried also with GParted, parted magic, I have tried also even by trying to configure it to raid 1 then HBA (Raid 0), again nothing.
Any recommendations, you will save me!
Best Regards,
Frank
If this SSD is connected to a host which is not a member of a vSAN cluster, then try and use the partedUtil commands displayed in the article linked by GreatWhiteTec. If those steps don't work and neither do the other offline tools you mentioned, then most likely your SSD is damaged and needs to be replaced. It's probably a good time to check and see if it's still under warranty where you can get it replaced.
If you're trying all these external utilities and it's still not erasing, then you have a bad drive. I've seen this before with other flash media and there's not much you can do other than to replace it. This may explain why when it was pulled from an older vSAN that it was in an "error state" as you say.
Before you can use PartedUtil you need to unload the vSAN VMkernel modules.

Try this:
esxcli vsan storage remove -d naa.5000c5003015fc7b
Hello Frank,
What kind of controller is this attached to?
Try this:
# dd if=/dev/zero of=/vmfs/devices/disks/<naa.###> bs=1M count=50 conv=notrunc
# partedUtil mklabel /vmfs/devices/disks/<naa.###> msdos
If this doesn't work and rebooting the host is not a problem then boot it with vSAN modules disabled (yes, yes I read where you said above that this was a non-vSAN environment but if so there is no harm in trying):
Press Shift+O before it starts loading the modules (the screen after hardware boot portion completes and you can see 'Shift+R' to rollback on screen (and Shift+O depending on build version))
After the boot UUID string append a space and then jumpstart.disable=plog,lsom,vsan,cmmds,virsto
Proceed to wipe the device using the commands above.
If this doesn't work then try mounting this to something else (e.g a Linux box) and performing similar.
If no joy...maybe it is physically broken, maybe try to find out its history (and warranty).

Currently: Dell H730p
I will go through your recommendations now...
Hello Frank,
"trying to configure it to raid 1 then HBA (Raid 0)"
H730 are pass-through only (for vSAN anyway) so these should not have any RAID configured on them and the controller mode should also be set to pass-through (yes I know - no vSAN here but humour me :smileygrin: ).
Additionally these controllers have a deeply troubled past and thus you should ensure you are using a stable and compatible driver+firmware combination.

:smileygrin: I tried to change the raid in order for the controller to erase the data on Seagate. But this did not work. Also unfortunately same error appears on second solution you proposed. It is stated that this disk is read only. I do not want to give 2.4k $ right now pff. As long as I am going to make this ssd work. This will be my next step to check firmware+driver on H730p....
I think I am going to install windows on my server only for this: Read Only Hard Drive FIX - Windows 7 - YouTube :smileysilly:
Unfortunately you were right.... I tried with windows, I also tried with some other extreme linux code. I could not get access to the driver. So I will check with warranty IFF I can do something, but I will have to find the initial owner and this ssd was pulled from a Xyratex who has now been acquired from Cray...
I put the pci ssd or the Controller as sharepoint pci
reboot host
add pci DEVICES to windows vm
format in Disk administrator, the remove the partition
u sharepoint the Pci ssd
now you can use for vsan or vms datastore
this always work for me
