Description

This article describes the procedure to be followed on a clustered Data ONTAP 8.x node (that was unjoined from a cluster) to wipe the configuration and re-initialize/reconfigure it.

Procedure

 

Ensure that each node from the HA pair, has disks assigned to it, and that neither of the nodes was previously in a taken-over state. This can be checked from a maintenance mode boot.

Perform the following steps:

  1. Boot each node to the LOADER/CFE prompt and ensure that the below variables are set. These variables remove the cluster RDBs, CDBs and the varfs from mroot, boot device and nvram.
    setenv bootarg.init.boot_clustered true
    setenv bootarg.factory_init_completed true
    setenv bootarg.init.clearvarfsnvram true
     
  2. Boot the node:
    bye
  3. When the nodes are booting, press CTRL+C to enter the Boot menu.
    *******************************
    * *
    * Press Ctrl-C for Boot Menu. *
    * *
    *******************************
    Boot Menu will be available.
     
  4. At the Boot menu, type wipeconfig on each node.
    Please choose one of the following:
    (1) Normal Boot.
    (2) Boot without /etc/rc.
    (3) Change password.
    (4) Clean configuration and initialize all disks.
    (5) Maintenance mode boot.
    (6) Update flash from backup config.
    (7) Install new software first.
    (8) Reboot node.
    Selection (1-8)? wipeconfig 
  1. After running the wipeconfig command, select option (4)
    Please choose one of the following:
    (1) Normal Boot.
    (2) Boot without /etc/rc.
    (3) Change password.
    (4) Clean configuration and initialize all disks.
    (5) Maintenance mode boot.
    (6) Update flash from backup config.
    (7) Install new software first.
    (8) Reboot node.
    Selection (1-8)?  4
  1. Answer yes to zero/erase all disks
    Zero disks, reset config and install a new file system?: yes
    This will erase all the data on the disks, are you sure?: yes
    Rebooting to finish wipeconfig request
  2. The init process can take a long time (hours, depending on the number and size of the disks), as the disks are zeroed and initialized.
  3. Once the init process has completed, the node will boot Data ONTAP and the login prompt will be available.
  4. At this time, a new cluster can be created or these nodes can be joined to an already existing cluster. The steps for creating or joining a cluster are available in the Clustered Data ONTAP® 8.3 Software Setup Guide.

 

Additional Information

  • The initialization operation can also be performed remotely through the SP. The initialization operation will not affect the configured SP.
