using can display text containing the line feed code LF (Line Feed).

Notes on operations of RAID Manager XP log files

Since RAID Manager XP log files are output to NAS OS LU, if Continuous Access XP Journal operations

still show an error, log files become large and available space on NAS OS LU decreases. You should

periodically check the capacity of log files (except trace files) to which RAID Manager XP restricts

capacity, stop RAID Manager XP, and delete log files using the horc_logremove command before

exceeding 1 MB. Check the log files' capacity using the following command.

$ ls -l -R /home/nasroot/log* (* means an instance number 16 or 17)
