Hi! =20
Our opinion of the LSI MPT target driver is that it is not good enough.=20
Maybe to use as a base for further developement. We had a guy here that=20
spended a lot of time with it, without any success. Maybe somebody else=20
could do a better job, but "warning".
I had some QLA iScsi HBA=B4s since they released them, and I tried to get=20
the target F/W from Qlogic, but they refused. I will try again, since I=20
also want the Fc target F/W.
We are now running a project to use EVMS volumes for target exportation,=20
currently with scst, but hopefully soon with stgt. We want to put access=20
control in EVMS.
Best regards from/Med v=E4nliga h=E4lsningar fr=E5n

For qlogic FC, it is the same as scst at this point, except we are based=20

Right now I am just trying to get what was in scst into tgt. So this=20
means qlogic 2xxxx card support first, then mpt, then I will bug qlogic=20
about their HW iscsi card and bug my boss to bug emulex. Tomo might be=20
working the HW qlogic iscsi card or mpt right now though too. Maybe=20
after we have at least qlogic we can try to stablize things (like finish=20
adding refcounting, do the eh stuff, redo the MSG=5F*, fix bugs, etc) and=20
then roll a release.
