hi
I am new to iscsi ,have some questions in learning,quite appreciate for
your help and time
This really isn't the place to ask about iSCSI targets, by the way. This
list is for discussion of the open-iscsi iSCSI initiator package.
But I'll try to answer your questions.
1 \ both lio-utils and tgt are pure user space program? Both of them are
using the kernel iscsi module ? So ,what is the difference between them?
No, I believe the tgt (or stgt) package uses a user-space daemon, but it
only handles administration of connections. The transport is handled by the
kernel. See http://stgt.sourceforge.net
The lio-utils package is being deprecated in favor of the targetcli
package. Right now, targetcli works on top of lio-utils, but soon it will
run standalone. See http://linux-iscsi.org/wiki/Lio-utils
The lio-utils/targetcli combo is configured in user space, but managed in
kernel space. There is no user-space daemon running in this case.
Difference between them: plenty. Configured differently, different
designs, and the Linux community has chosen targetcli moving forward. I
have *not* benchmarked them, so I have no idea if one performs better than
the other. Also, targetcli doesn't yet have every feature that tgt has,
such as iSNS support, but targetcli is being actively developed/improved.
2 \ Are there any guide documents on how to setup a iscsi target using
both tgt and lio-utils?
I have created some simple example documents, but they are SUSE-based. I
haven't published them yet, but was thinking of setting up some place where
I could do that. I could probably email them to you if you thought they
might be useful.
Note: if you use targetcli, try the manual page, as it has enough
information to set up a simple target.
Thanks a lot for your help and time !
