Dell PowerVault MD3600f – Error in Deleting Virtual Group
I wanted to unmap two Virtual Disk from hyper-v 2019 host node. Whenever I tried to delete the Virtual Disk mapping I got the error message below:
„Error 219 – The operation cannot complete because the virtual disk has a persistent reservation placed on it. Please release the reservation at the host and then retry the operation“
To view persistent reservations use smcli.exe, which is stored in C:\Program Files\Dell\MD Storage Software\MD Storage Manager\client.
