Spectra Logic NTIER700 User Manual

Working with the Hardware Components

June 2010

If the library uses one of the tape drives to provide the robotic control 
path through ADI, you may need to reinstall the Media Changer driver 
using the Windows Add Hardware wizard. The Spectra Logic device 
driver is located on the nTier700 system disk at:

C:\Program Files (x86)\SpectraLogic\drivers\

Spectra T Series Library Driver

\SpectraMC.inf

 

A medium changer driver is unnecessary in most configurations. 
The general practice is for the software to control the library 
directly, so there is no need for a robotics driver at the OS level.

Three known exceptions are for Windows RSM (Removable 
Storage Manager), DPM (Data Protection Manager), and File 
Migrator (or XenData). If you have one of these, right-click on 
the Unknown Medium Changer and choose 

. Use 

the Windows Add Hardware wizard to install the driver.

ƒ Extending blades. After powering off a drive that needs replacing, pull 

the blade containing the drive out from the chassis gently to prevent 
possible vibration issues with the other drives, which are still powered 
on and running.

ƒ Moving drives between blades or units. The drives in each blade are 

configured as a single RAID set. Spectra Logic strongly recommends 
against moving drives from one blade to another or from one Spectra 
nTier product to another. Contact SpectraGuard Technical Support if 
you want to move drives (see 

).

ƒ Expanding capacity. Any upgrade to add one or more blades to the 

originally purchased configuration must be performed by Spectra 
Logic Technical Support (see 

). 

ƒ Removing a blade. The blades in the nTier700 are not hot-swappable or 

hot-pluggable. Contact Spectra Logic Technical Support (see 

) if you need to remove a blade.

Moving drives from one blade to another or from one nTier to another can 
potentially result in lost data.

Do not remove a blade unless specifically instructed to do so by Spectra Logic 
Technical Support.
