NAME

       vollogcnvt - Logical Storage Manager BCL-to-DRL logging conversion utility

SYNOPSIS

       /usr/sbin/vollogcnvt [-g diskgroup]

OPTIONS

       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.
