Why does node report ADP disabled while upgrading ONTAP or reboot

Last Updated:

Applies to

  • FAS
  • AFF
  • ONTAP 8.3.1 and later


  • Advanced Disk Partitioning (ADP) is enabled by default on all FAS/AFF models running ONTAP 8.3.1 or higher.
  • However, ONTAP disables the ADP feature when it is not needed. Possible scenarios include:
    • Systems using unpartitioned disks for root aggregates.
    • Systems using technologies such as Storage Pool, MCC-FC etc.
  • On such systems, when the node gets reinitialized during the ONTAP upgrade, ADP is disabled again so that its original system configuration remains the same.
  • This message will also be seen after a reboot of a node during the boot up process.  A typical EMS message will look like:

Wed Mar 17 10:27:41 -0500 [node-03: sysinit_thread:]: Disk auto-partitioning is disabled on this system: ADP DISABLED.
