Chapter 6 Storage Screens

NSA-2401 User’s Guide

You can view information on the NSA internal disks in this screen. 

See the Quick Start Guide for information on replacing disks in the NSA. When replacing a 
disk in a degraded or down RAID array, the new disk must be at least the same size or bigger 
than the array’s smallest disk, so the NSA can restore all data in the array. For optimal 
performance, all disks in the array should be the same model, capacity, and speed.

For example, if you have RAID with 250 GB disks, you must put in a 250 GB or bigger disk as 
a replacement in order to restore all original data in that array. If you use a bigger disk, the 
extra space on the disk will not be used.

"

The NSA automatically repairs a degraded RAID if you insert an empty disk 
without an existing file system. Otherwise, when you replace a disk you must 
go to the Storage > Internal Storage > RAID screen, select the degraded 
array, and click Repair. 

Click Storage > Internal Storage > Disk to display the following screen. This screen 
provides information on disks installed in the NSA.

Hot-Spare

This is the array’s standby drive if it has one. “There are not disks” 
displays if the array does not have a standby drive.

Free

These are installed disks that do not already belong to a disk array.
