* Treating HP SmartArray physical disk as LSM disk.
* Depending on output of command "hpssacli ctrl all show config detail"
* Only support Disk.STATUS_FREE, Disk.STATUS_OK and Disk.STATUS_OTHER.
# Seeking server to investigate on spare disk and faulty disks.
* Including physical disk location in Disk.name.
* Set Capabilities.DISKS.
