Re: Hp p420 raid controller in hba mode
Hello christian_domes,
I don't think P420 can be used in HBA mode as there is no indication of HBA mode/Mixed mode in the quickspecs of the controller (https://h20195.www2.hpe.com/v2/getdocument.aspx?docname=c04111534#)
Hope it helps!

Hello,
you can set the P420 to hba Modus, but the Disk will not shown as Raw Disk, they are only available as ciss Device and not as raw Device. Its not recommended to use for ZFS.
best regards ré

Hello,
Take the complete data backup before convert the HBA mode and follow the below steps.
1.Boot to HP Smart array configuration utility (F10)
2.Erase all RAID array (you can choose "Clear configuration" option)
3.Choose "Enable HBA Mode"
4.Reboot server
Follow the below HPE Smart Storage Administrator User Guide (Page no#48)

I found other materials online that claim otherwise. Can you share more info on why ZFS on P420 in HBA mode is a bad idea?

Hi,
the Disks will not shown as raw Disk, they are only available as ciss Device and not as raw Device. ZFS like raw Devices...
