NAME

tkadmin disable lvol - makes a logical volume inaccessible for I/O

SYNOPSIS

tkadmin disable lvol -server servername lvolname

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. 

DESCRIPTION

The tkadmin disable lvol command makes a volume inaccessible for I/O. Disabling a logical volume with this command persists across server restarts. Disabling volumes can be used to speed restart and recovery if the Toolkit server uses many data volumes. 

CAUTIONS

Disabling a volume is not allowed unless the server is in administrative mode. However, in administrative mode all volumes are inaccessible. So disabling a volume in administrative mode actually affects the state of the volume at the next restart. Disabling a volume could prevent the server from restarting the next time around. Volumes needed for server restarts must not be disabled. A logical volume should only be disabled when the user plans to delete it. 

EXAMPLES

The following command disables the logical volume lvol8:

% tkadmin disable lvol lvol8

PRIVILEGE REQUIRED

Encina RQS administer (a) permission to the RQS server

Encina SFS administer (A) permission to the SFS server
