2 Click OK to close the warning window and proceed, or click Cancel

 

 

to abort the unlabeling process. If you click OK, a status window

 

 

appears.

 

3 Click Close when the status displays Success. The Label Disk

 

 

Device screen now shows the device with no label name.

 

 

 

 

 

Note: If you decide later to make an unlabeled device usable by

 

 

the StorNext File System, you must first relabel the device.

 

 

The relabeling process is identical to labeling initially, as

 

 

described in Labeling a Device on page 98.

 

 

 

 

Probing a Device

 

Use the following procedure to probe a disk device.

 

1 After selecting from the Disk Devices box the device you want to

 

 

probe, click Probe. The Probe Disk Device Status window appears.

 

2 Click Close when the status displays Success.

 

 

 

 

 

Note: The probe should activate the light on the disk or RAID.

 

 

 

 

The global section of the file system configuration file contains general

Making Global Changes

parameters that control system performance, components related to the

 

 

file system’s resource consumption, and whether features are enabled or

 

disabled.

 

For most of these parameters, restarting the File System Manager (FSM)

 

causes the modified parameters to take effect. However, the File System

 

Block Size and Windows Security parameters require that the file

 

system be remade before they take effect. Remaking the file system

 

results in data loss, so you should carefully plan the initial configuration

 

of these two parameters in order to reduce the number of file system

 

remakes. If a parameter change requires a file system remake, the system

 

notifies the administrator in the system log.

 

The global section also contains several parameters that can dramatically

 

improve or degrade system performance, so you should exercise caution

 

when modifying performance parameters.
