NAME    [Toc]    [Back]

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

SYNOPSIS    [Toc]    [Back]

       /usr/sbin/vollogcnvt [-g diskgroup]

OPTIONS    [Toc]    [Back]

       Limits the conversion of logging subdisks  to  volumes  in
       the specified disk group.

DESCRIPTION    [Toc]    [Back]

       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-toDRL
 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.
