NAME

  switchlog - moves an AdvFS file domain transaction log

SYNOPSIS

  /sbin/advfs/switchlog	domain_name vol_id

OPERANDS

  domain_name
      Specifies	the name of an existing	file domain.

  vol_id
      Specifies	the number of the new volume to	use for	the log.

DESCRIPTION

  The switchlog	command	relocates the transaction log of the specified file
  domain to a different	volume in the same file	domain.	 Moving	the transac-
  tion log within a multivolume	file domain is typically done to place the
  log on either	a faster, less congested, or mirrored volume.

  Use the showfdmn(8) command to determine the current location	of the tran-
  saction log. In the showfdmn command display,	the letter L displays next to
  the volume that contains the log. The	showfdmn command also displays all of
  the volumes and their	volume numbers.

RESTRICTIONS

  You must be the root user to use this	command.

EXAMPLES

  The following	example	displays the log's current location by using the
  showfdmn command and then moves it to	volume 2 by using the switchlog	com-
  mand.
