Data write protected - can not remove write protection

We are currently having construction done on our building, and the construction crew cut off power to my server room while I was at lunch. The UPS's went hard, but didnt last long enough for me to find out and get them to restore power. Because of it, A few of my servers and my storage array had the power cut abruptly. The array is a Dell emc-ax4 enclosure connected via iSCSI to a windows server 03 machine. After I rebooted, the iSCSI connection was initially gone, but I was able to reconnect after re-configuring and my data was there. However, all the data is now "read only" i am able to uncheck the read only box and apply, but It gives me errors and Does Not remove the read only attribute. I found this article and tried these commands, but it says they cannot remove the attribute. https://support.microsoft.com/en-us/kb/326549

I am not the expert in this, but were the permissions affected? Have you checked?

you are going to have to go into your storage manager and diagnose why it is in a fault condition and only mounting the lun(s) as read-only.  This is done to prevent further damage to your files.  The LUN is read only not the files so by approaching it from the windows level is pointless

You are aware that WS2K3 is no longer a supported product. You should also check that the batteries in your cache controllers are functional (replace every 3-5 years)

Most UPS's have a power monitoring utility i.e. APC's Powerchute that when the UPS is running out of power  allows you to do an orderly shutdown to prevent this scenario from repeating.

I went through the data admin software (navishpere express) to try and remove the write protection. there wasnt any way to do it. I ended up copying the data to our new NAS, and when it was copied over it lost the write protection. That was the short fix for now, I will keep trying to remove the write protection next week and report back.

OK, so I went through diskpart.exe and ran a couple of scripts. I typed "detail disk" and saw that read only was set to yes. I was able to clear the read only attributes with "attribute disk clear readonly" and then did another "detail disk" showing the read only status to no
