DSMSERV EXTEND LOG (Emergency Log Extension)

Use this command to extend the size of the recovery log when you need additional log space to restart the server. After the server is running, you can do the following:

Note:Use the DSMFMT utility to format a new recovery log volume.

Syntax

>>-DSMSERV EXTEND LOG--volume_name--megabytes------------------><
 

Parameters

volume_name (Required)
Specifies the name of a new, formatted volume available for use as the recovery log extension.

Specify either a regular file name or, if you are using a raw partition, a symbolic link to a character special file. A regular file name can be either a fully qualified path name or a path name relative to the current working directory. For example, if the file name is mainvol and the current working directory is /opt/tivoli/tsm/server/bin, the volume name would be:

/opt/tivoli/tsm/server/bin/mainvol

A symbolic link to a character special file would be entered in the format:

/dev/.../rdsk/.../fn

Where /... is zero or more directories and fnis the file name. For example,

/dev/rdsk/c1t34ds6
Note:TSM cannot always detect if data already exists on a raw partition. Existing data can be destroyed if you define a volume to that partition.

megabytes (Required)
Specifies the size, in megabytes, of the new volume. The size must be a multiple of 4MB and 1MB less than the size of the volume specified in the volume_name parameter. For example, if the volume is 5MB, specify a value of 4.

Examples

Task

The server halts, and there is not enough recovery log space to restart. After you have formatted a 21MB volume named new.reclog, extend the recovery log using the new volume.

Command:
dsmserv extend log new.reclog 20
