Growing a Windows iSCSI LUN from a NetApp Filer
Proceed with caution: I've done this hot. Even through the
extend command appears to unmount and then re-mount the partition, no interruption in service was recorded. Your backups
are good, right?
Begin with the filer.
- locate your LUN, identify its volume
- Grow the affected volume (Which implies you may need to grow the aggregate as well)
- Grow the LUN
Next go to the Windows server
- Open a command propmt
- launch diskpart
- select the iSCSI disk
- select the partition to grow
- type extend(or possibly expand).
