NAME

tkadmin flush lvol - propagates buffered changes to one or more logical volumes

SYNOPSIS

tkadmin flush lvol -server servername [-lvolname 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 lvolname] Specifies the specific logical volume for which you want to propagate all buffered changes. 

DESCRIPTION

The tkadmin flush lvol command propagates all buffered changes to the volume for one or all of a server’s data volumes. (The Recovery Service maintains a buffer pool of pages belonging to data volumes under its control. The buffer pool is managed as a write back cache; that is, page updates are cached in the buffer pool and propagated to the data volumes at some time later.) To flush the changes of one specific data volume, use the -lvolname option. To flush the changes of all data volumes associated with the server (for which changes are buffered), do not specify a specific volume. 

CAUTIONS

This command is not intended to be used with log volumes. If used on a log volume, the command returns an error. 

EXAMPLES

The following command flushes all the buffered changes to all logical volumes associated with the /.:/branch1/server/sfs1 server. 

% tkadmin flush lvol -server /.:/branch1/server/sfs1
