NEWMIRRSET 

The NEWMIRRSET command creates a new mirrored volume set by initializing
the master of the volume set.

The volume that will be initialized as the new volume master must be
mounted in the SCRATCH or UNKNOWN state.

Task 

Creates a mirrored volume set.

Syntax 

     volutil: NEWMIRRSET [SNAME=]sname 
                         [MASTER=]master 
                         [LDEVS=](ldev,ldev)
                         [ [PERM=]percent_perm][ [TRANS=]percent_trans]
                         [ [GEN=]gen_number]
                         [ [CLASSES=](cname[ [,cname]...])]

Parameters 

sname                 The name that you assign to the new volume set.  It
                      is used to reference and identify the set.  It must
                      be a unique name at the time of initialization.  No
                      other volume set with the same name can be mounted
                      on the system.  Required.

master                The name that you assign to the master volume of
                      the set.  This name need not be the same as the
                      name assigned to the volume set.  Required.

ldev,ldev             Two numbers from 1 to 999 that specify the logical
                      devices that are to become the mirrored master
                      volumes of the volume set.  They must identify two
                      different devices configured into the device class
                      DISC. The volumes must be mounted in the SCRATCH or
                      UNKNOWN state.  Required.

percent_perm          A number between 0 and 100 that specifies the
                      maximum percentage of disk space that can be
                      allocated to permanent data (files, databases).
                      Default is 100.  Optional.

percent_trans         A number between 0 and 100 that specifies the
                      maximum percentage of disk space that can be
                      allocated to transient data (process stacks,
                      virtual objects).  Default is 100.  Optional.

gen_number            A number from 0 to 32,767 that specifies the
                      generation of the new volume set.  Default is 0.
                      Optional.

cname                 The names of volume classes to be initially created
                      in the volume set.  The MASTER volume (volume being
                      initialized) is assigned to these classes.  If this
                      parameter is omitted, the volume class DISC is
                      created and the MASTER volume is assigned to it.
                      Optional.

Example 

This example shows how to use the VOLUTIL NEWMIRRSET command.  If you do
not specify a volume class, the default volume class DISC is added to the
mirrored volume set.
