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).
DISKPART> list disk

Disk ### Status Size Free Dyn Gpt -------- ---------- ------- ------- --- --- Disk 0 Online 68 GB 4064 KB Disk 1 Online 165 GB 65 GB

DISKPART> select disk 1

Disk 1 is now the selected disk.

DISKPART> list part

Partition ### Type Size Offset ------------- ---------------- ------- ------- Partition 1 Primary 100 GB 32 KB

DISKPART> select partition 1

Partition 1 is now the selected partition.

DISKPART> extend

DiskPart successfully extended the volume.

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
