After kernel version 2.6.33 for HP SmartArray storage controllers the driver changed.
Actually cciss is a driver for a raid controller, the new hpsa is a driver for SCSI/SATA/SAS block devices.
Also this changes the device names: /dev/cciss/c0d1p1 -> /dev/sda1 .
However this can be configured with a driver paramater.
Unfortunately not all of the utilities can be used anymore. For example arrayprobe is compatible with the new driver.
Fortunately HP’s official utilities are still available and usable:
check_hparray for nagios:
Far better using apt:
Lucid packages can be used on Natty and probably Lenny on Squeeze.
