Support for smart array #90

Closed nishant-dash closed 6 months ago

nishant-dash commented 10 months ago

Since hardware observer right now (edge, revision 15) looks at lshw to get raid information, this does not work with smart arrays like on HPE ProLiant DL380 Gen10 which do not show in lshw but they do show in ilorest

Interesting... does the array at least show up in lspci?

aieri commented 7 months ago

@nishant-dash I would like to keep the hardware detection routine independent of external resources. Is there really no other way to detect the presence of a smart array? Maybe via the /sys filesystem, dmidecode, lspci, or even IPMI commands

nishant-dash commented 7 months ago

Hi @aieri I looked into dmidecode, and I can find it under dmidecode -t 203 since it shows up with type 203 which means its OEM specific. I also found it under /sys/devices/pci.../.../.. or perhaps the easiest and quickest to get format would be from

hwinfo --storage

Thank you, we can work with that. Does hwinfo --storage-ctrl also report its presence?

nishant-dash commented 7 months ago

it does, although I see the exact same output with hwinfo --storage-ctrl as I do with --storage

nishant-dash commented 7 months ago

also I see almost the same output (but less info) with lshw -storage (it mentions Smart Storage PQI SAS but does not say HPE Smart Array...)
