I addressed this issue with the response center and was told that it not advisable to remove subsets of the log files since they are tracked in the LOGCATLG file. HP sent this procedure for removeing hparray log files.
1. /sbin/init.d/hparray stop
2. mv /var/opt/hparray/log/* /tmp
3. touch /var/opt/hparray/log/LOGCATLG
4. /sbin/init.d/hparray start
