Re: HPE H240 in HBA mode



I have seen some somewhat official recommendations from HPE to leave such controllers in RAID mode and to then create an individual RAID 0 target for each disk.

It seems more complicated than is needed, but it's what they said to do and it did seem to work.

Cheers

Hej,
while trying to get rid of the issues with the mfii driver when running xen, i popped in a H240 controller int o my DL380.  This works fine, but there seems to be no real driver for that Card.  When running in RAID mode, ciss claims this device and works.  But I want to avoid double raid overhead (this runs zfs), so I configured the controller to HBA-mode.

Obviously, the ciss driver now does not recognize the connected drives:
[     1.000003] ciss1 at pci12 dev 0 function 0: HP Smart Array 10
[     1.000003] ciss1: interrupting at msix6 vec 0
[     1.000003] ciss1: 0 LDs, HW rev 1, FW 7.00/7.00, 64bit fifo rro, method perf 0x20000005
[     1.000003] scsibus2 at ciss1: 0 targets, 1 lun per target
Looks to me ciss only operated with the HP virtual disks.
Is there a driver for HBA mode on these cards?

Cheers
