I Queisced the SnapMirror destination to pause any updates
ndmp-copy /vol/source /vol/destination
Problem is that when I connect/mount these LUNS (for DR test) windows reports "media is write protected"
lun show shows the lun as r/w
if I create a clone of the lun then I still have the same problem
if I create a new LUN inside the same volume it works fine
Any suggestions? Im in the middle of a DR test and cant progress until I sort this, I logged a call with NetApp support and was told they were in the middle of a shift change and couldnt help me at the minute
You are running ndmpcopy on the target? Have you tried mounting a clone on the target instead? It sounds like a lun attribute or change needed from windows to change from readonly on the lun object (I remember having to remove the hidden attribute and readonly before.. from fdisk I think - support was able to give us a kb). But a clone from the target should work... you can then ndmpcopy that clone if you need a copy out elsewhere (assuming the copy of the readonly volume is the issue).
Thank you… yes it was diskpart we used to clear the hidden and readonly flag… but I would clone the mirror instead of copying…then copy if needed. Since you are working with mirrors and copies the good news it won’t affect any production.
