Need to hotplug a HP smartarray LD drive and to be seen on the system
Issue
- Existing raid array (raid0) created on P420i got failed due to an issue with physical disk.
- Replaced disk and rebuilt raid-array at controller using hp provided hpacucli utility and it is showing as good at controller
- But not visible / not able to scan at system level.
lsscsi -g
