Cpqarrayd is a userspace monitoring daemon for HP (Compaq) SmartArray hardware RAID controllers. These controllers usually come built-in to ProLiant, or as a PCI card for ProLiant or Integrity systems. This daemon reports status changes in the disk array to syslog and, optionally, to a snmp trap host.

The default is to only log to the syslog. You can specify traphosts with the -t parameter at the commandline. Multiple traphosts are allowed.

This tool works with the SmartArray drivers found in Linux kernels (cciss and ida drivers).
