Hi!

I downloaded sources and figured out, that the problem is in static
buffer in VBox initiator. iscsi-scst tries to send sensitive data sized
96 bytes. I don't know, what this data is, but VBox denied our iscsi
disk because of this buffer. I increased static buffer size to 96 bytes
(sense[32] -> sense[96]) in VBox iscsi initiator module, compiled it,
and now it works just perfect.
Thanks, fixing such problems have been on my todo list already.
Had enough time today to squeeze it in - been waiting for a sporadic
error to show up...
I'm attaching patchfile against version 3.1.4_OSE
Do you think, it's acceptable for stable releases?
The fix will break again when some iSCSI target comes around which
provides even more sense data, so it is just one step.
So from my point of view the solution is to both apply your patch and
also make VirtualBox a little less paranoid. Having to truncate sense
data is no error situation, so it should be handled gracefully.
Again, thanks for providing the patch and reminding me.
The code change for this issue is in r27181. Note that there have been a
number of more or less significant iSCSI fixes over the last weeks.
Unfortunately it's not possible to use the ISCSIHDDCore.cpp file
straight from trunk, as a few things have been changed since 3.1 in an
incompatible way.
