NAME

tkadmin remove mirror - removes a mirror from an Encina logical volume

SYNOPSIS

tkadmin remove mirror -server servername lvolname pvolname

ARGUMENTS

-server servername Specifies the server affected by the command. The server name is the name that is registered with the DCE Directory Service. If the server name is not specified in the command line, it is retrieved from an environment variable, ENCINA_TK_SERVER. 

lvolname Specifies the logical volume for which the mirror is being removed. 

pvolname Specifies the physical volume that stores the mirror. 

DESCRIPTION

The tkadmin remove mirror command removes the mapping between the logical volume and the physical volume. If there is only one physical volume backing the logical volume (only one copy, no mirrors) and you try to remove it with this command, the command fails. The logical volume should be deleted using the tkadmin delete lvol command. 

CAUTIONS

This is a dangerous operation. Removing mirrors reduces the availability of the data stored on the logical volume. 

NOTES

This command is not for use on the AIX operating system. 

EXAMPLES

In the following example, the pvol3 mirror of the data stored on the lvol8 logical volume is removed:

% tkadmin remove mirror lvol8 pvol3

PRIVILEGE REQUIRED

Encina Monitor administer (a) permission to the node manager

Encina RQS administer (a) permission to the RQS server

Encina SFS administer (A) permission to the SFS server
