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 utility is a migration tool for Logical Storage Manager
  (LSM) administrators who are using the Block-Change Logging (BCL) feature.
  In the Version 5.0 release of Tru64 UNIX, the BCL feature of LSM was
  replaced with the Dirty-Region Logging (DRL) feature.

  The vollogcnvt utility 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 message 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 are dissociated from their
  volumes only if at least one of the log subdisks for the volume is
  converted.  Otherwise, the configuration does not change and logging is
  disabled. Volumes that cannot be converted, for example, because all their
  log subdisks are too small, will have logging disabled.

  At system startup, the vollogcnvt utility runs automatically and logs
  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 utility
  runs at startup or manually, a message is sent to the console.

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