[Cpqarray-discuss] Is RA4100 redundancy supported on Linux ?

[Manimay B. <ma...@cd...>]

Hi,
we have Linux 7.2 installed on Compaq ML530 rack mounted setup . There
are two RA4100 controllers
plugged onto the RAID box in active/standby mode. But we notice that if
one of the cards (say active) is
jacked out a message stating implicit logout of RA controller port (id)
is displayed . That means the cpqfc
driver is able to detect the event but it still allows us to write onto
the RAID. Once the system is rebooted ,
the file we wrote disappears. Does it mean that the standby controller
could not take over on plugging out the active one ? To our surprise ,
it even lets us access (write) the RAID if both the controllers are
plugged out
from the RAID box or from the Fiber channel HUB (HBA end) ! From this it
seems that the data actually is
written somewhere between the driver and the HBA (RA4100 controller
posted write caching does not come
into the picture as both the controllers are disconnected throughout) .
Please help us .
TIA
