Enabling/disabling disk shadowing

Enabling or disabling

disk shadowing

If you have the disk shadowing feature, disks are added to

Meridian Mail in pairs. When the new data is written to disk,

both drives in a pair are updated at the same time with the

same information. If one of the drives in a pair fails, it can be

removed and replaced at maintenance time with minimal

disruption to service.

To enable or disable disk shadowing, follow these steps.

Step Action

1 From the Logon screen of the administration

terminal, press the [Logon] softkey, enter the

administration password, and press <RETURN>.

Result: The Main Menu appears after a successful

logon. The menu is a routing menu from which you

can select the utility you want. Never leave the

administration terminal unattended while you are

logged on.

2 Select System Status and Maintenance.

appears.
