System operations within utilities
Introduction
Once you have upgraded to or installed your Meridian Mail
Release 12 system, you will be required to manage it. The
utilities overviewed here and described in the later chapters
are the key to maintaining a healthy system.
Toggle disk to disk
backup
The following points apply to toggle disk to disk backup:
• A disk to disk backup does not require a keycode.
• Disk to disk backup is performed on systems that have
one disk per node.
• Disk to disk backup is not available on single-node
systems, 2
-
node 26-hour systems, 3
-
node 30-hour
systems, 4
-
node 45-hour systems, or 5
-
node 60-hour
systems. For more information, see “Volume sizes” on
page 2-55.
• Disk to disk backup is not an option on MSM systems or
card option systems.
Standardize volume
sizes
The following points apply to standardize volume sizes:
• Standardize volume sizes does not require a keycode.
• Standardize volume sizes cannot be reversed.
Restore system from
backup
The following points apply to restore system from backup:
• A keycode is not required to restore a system from
backup because this is considered a maintenance
procedure.
• You must have a recent copy of the system’s database on
a backup tape in order for this procedure to be
successful.
• Performing regular and frequent (at least weekly)
backups is essential.
• The restore procedures are slightly different if the system
has disk shadowing. You will be restoring from the
surviving disk, rather than from an external backup tape.
