you really make it very difficult for me, why couldn't you include information which paste is for which command!

[glensc]

state of "cachecade0" Volume is not retrieved.
should such type volumes ("CacheCade") be skipped completely?

need to search what is it. if you have link to such doc, it will help fixing this sooner.

thanks for your patience.
this is some (rather shallow) information about cachecades: https://www.thomas-krenn.com/en/wiki/MegaRAID_CacheCade_SSD_Cache - not sure though, if this is sufficient.

A broken cachecade would have a noticable impact on the raid performance, so in my opinion ignoring them is not the best idea, but totally ok as a workaround. ;-)

This documentation from LSI themselves might provide a deeper insight into the matter:

Can you induce failure with cachecade and send me output of such commands? as i don't know what to parse in case of failure...
