/var/log/isi_phone_home.log can grow without bound and fill up /var partition, causing issue with CELOG event generation and other operational issues with processes

Issue: /var/log/isi_phone_home.log can grow without bound and fill up /var partition, causing issue with CELOG event generation and other operational issues with processes

Cause: Log rotation does not work to auto rotate log file generated by isi_phone_home

Fix: if /var is getting too full (>85%) for any of the nodes, then run the following command:
# isi_for_array 'truncate -s 0 /var/log/isi_phone_home.log'
