Hello all,
I´ve run in some problems here. I´m not very familiar with FC-technology
and now got the task of installing suse 7.0 with a IBM FAStT Hostadapter
(Qlogic ISP 2200 FC) at my hands. The hostadapter connects through fc to
a
array with a IBM FAStT 500 RAID Controller.
I´ve already found out that two hostadapter drivers exist: one in the
standardkernel (qlogicfc.o) and one from qlogic. Does anyone knows which
one to prefer? Will the Qlogic-driver work with 2.2.18?
Ok, here is my confusion: the hostadapter is redundant and therefor got
two controllers (channels?), both connecting via fc to the RAID
controller/array. When the array is, for example, configured as two
logical drives, the kernelmodul reports 4 devices (/dev/sdc, /dev/sdd,
/dev/sde, /dev/sdf), from which only two are usable. Is that "normal"
behavior? What happens in the case of a controller-failure?
Thanks for every tip and answer,
Goetz Rieger
