Unable to delete read only LUNs

Emadul-Islam

Hi there,

I'm trying to delete a LUN from Ontap 9.7. It throws an error as "ONTAP API Failed: Read-only file system". I tried from CLI with "-f" flag. Still getting the same error. Any idea how I can delete read-only LUN.

Regards,

Emadul

The hosting volume was sitting idle. I deleted the hosting volume and that took care of the LUNs that I was unable to delete.

Hello my friend,

What is the volume type where this LUN is hosted?

Which command did you use on CLI for the deletion attempt?

Regards,

Pedro

Hi Pedro,

I believe the volume type is “DP” and I used this command to delete “ lun delete -vserver SVM2 -path /vol/MX02_mirror/MX02_PUBFOLD -f”.
