the question is, can one get RAID status from command line?

yes but one needs to manually download and install:

# find a failed drive
hpacucli ctrl slot=0 pd all show

hpasmcli

hpasmcli is a scriptable command line interface for interacting with the hpasmd or hpasmxld management daemons. It is used to view/set/mod ify BIOS settings such as hyperthreading, boot control, and UID LEDs.

It can also be used to display hardware status, such as fans, power supplies, etc. The CLI supports TAB completion of command names and has a history buffer that can be accessed using the up/down arrows.
