This article describes how to restore NetScaler SDX to factory default settings.

 Important Points to Note

1. The procedure mentioned in this article is for troubleshooting or a last resort step only. The recommend procedure to restore.
2. Before performing a factory reset, back up all the data stored on the appliance, including the settings of all the NetScaler instances provisioned on the appliance. Citrix recommends that you store the files outside the appliance.
3. During the factory reset operation,  as a part of reboot,  the system may appear to be stalled or hanging,  but it is not.  Please give enough time for operation to complete.
   If possible,  please use LOM virtual java console that provides  additional details on progress of factory reset.

There are different procedures for RAID and non-RAID storage appliance. Before starting the procedure 

Non-RAID Storage SDX

Complete the following steps to restore NetScaler SDX to factory default settings:

1. Run the following command from the CLI of NetScaler (XenServer level):
   • sfdisk --change-id /dev/sda 1 c
   • sfdisk /dev/sda -A 1
   • reboot
2. Reconfigure SVM using article CTX130496 - How to Configure the Service VM on a NetScaler SDX Appliance .

RAID Storage SDX

Complete the following steps to restore NetScaler SDX to factory default settings:
Note: If you are using NetScaler SDX 22XXX/24XXX platform series, even though this is a RAID platform it still has /dev/sda1 as the factory partition. Follow the "Non-RAID Storage SDX" procedure to reset NetScaler SDX 22XXX/24XXX to factory default settings

1. Run the following command from the CLI of NetScaler (XenServer level):
   • sfdisk --change-id /dev/md_d0 1 c
   • sfdisk /dev/md_d0 -A 1
   • reboot 
2. If the appliance is in rescue mode prompt, then run the following command from the CLI of NetScaler (XenServer level):
   • sfdisk --change-id /dev/md125 1 c
   • sfdisk /dev/md125 -A 1
   • reboot 
3. Reconfigure SVM using article CTX130496 - How to Configure the Service VM on a NetScaler SDX Appliance .

For some models the NICs may be removed after reset procedure due to firmware updates over versions. Updating the SDX appliance after factory reset should resolve this issue.
