Under Configuration > System > Events we are seeing below error message "Disk1 expected 2" :

Re-seat the hard disk by doing below steps and see if that resolves the issue.

Shutdown the device > take out the HDD from the back of SDX device and re-seat the HDD properly > Restart appliance.

Now login to the GUI of SVM and we should not see the disk error.

Note: If you still see the same error message after properly placing the HDD then please contact Citrix support for further investigation
