vollogcnvt(8)
NAME
  vollogcnvt - Logical Storage Manager BCL-to-DRL logging conversion utility

SYNOPSIS
  /usr/sbin/vollogcnvt [-g diskgroup]

OPTIONS
  -g diskgroup
      Limits the conversion of logging subdisks to volumes in the specified
      disk group.

DESCRIPTION
  The vollogcnvt script is a migration tool for Logical Storage Manager (LSM)
  administrators who are currently using the block-change logging (BCL)
  feature. Beginning with the Version 5.0 release of Tru64 UNIX, the BCL
  feature of LSM is being replaced with the dirty-region logging (DRL)
  feature.

  The vollogcnvt script attempts to convert volumes with BCL enabled to
  volumes with DRL enabled. If called without specifying a disk group,
  vollogcnvt attempts the BCL-to-DRL conversion for all volumes across all
  disk groups.

  If logging cannot be re-enabled in the DRL scheme, a warning is sent to the
  console.

  For volumes whose BCL subdisks will not work in the DRL scheme, logging is
  disabled.

  Log subdisks that cannot be converted to DRL will be disassociated from its
  volume only if at least one of the log subdisks for that volume could be
  converted.  Otherwise, the configuration will not change and logging will
  be disabled. Those volumes that could not be converted, for example all of
  its log subdisks are too small, will have logging disabled.

  At system startup, the vollogcnvt script runs automatically and logs such
  errors to binlog and sends mail to root.  This happens at each reboot until
  the DRL is manually converted or when logging is disabled.  If the script
  runs at startup or manually, warnings are sent to the console.

  For details and guidelines on using DRL, refer to the Logical Storage
  Manager guide.
