Can't set up HP Smart Array P410 in RAID 5 mode

Solution 1:

This card has a poorly documented HBA mode, which is not supported by HPE nor in the Linux kernel (without custom out of tree patches), and it looks like the previous owner may have switched this card into that mode. The normal HPE utilities cannot turn this card's HBA mode on or off and the card will always report HBA mode as not supported, even when it's active.

You'll need a third party tool hpsahba to check the actual status of HBA mode on the card, and to disable it if it is enabled.

For example:

Card info:

hpsahba -i /dev/sg1

Disable HBA mode:

hpsahba -d /dev/sg1
