Write Working Set:

Parameter detailing how much data is to yet to be written to disk; size dependent on system activity.
Performance parameter (arraydsp -m) is the ratio of data to be written vs RAID 0/1 disk space.
Since data should be written to RAID 0/1 disks, ratio should always be < 1; otherwise, performance issues will result.

/etc/hpC2400/arraymon.dest file contains destinations for error messages. If you update it, kill and restart arraymond.
