Comment # 50 on bug 1044294 from Holger Schranz

Hello Johannes,

please forget my comment #48.

This was a mistake. About the patch you wrote in . It is possible to get this
in a
file?

Meanwhile we update the system to 4.4.90-18.32.

>From my point of view it looks better. A reboot with reconnect runs in 95%
without problems. A hard broken (Crash of the Initator system) runs into the
same behavior (a picture will be upload in parallel). Also the test which I
have described in comment #35 occourd further. But his can be, because I don't
use the patch from you.

About a description ... sorry ... it is a huge description and need a longer
time.

Short:
The "RAID"-System is a LEAP 42.2 virtual system. There are 5 files via QEMU
configured as HDD's. This 5 files are described as HDD's-RAID via tgtd. this is
necessary because of VPD which we need. This internally mapped and forward to
FCoE

The first part is for QEMU the next 2 parts are for tgtd because
of a 2 way connection.

Both 10:0:0:15 and 11:0:0:15 are connect to 1:0:0:15

Present to FCoE is via lio/targetcli.

I hope you are not so confused. 

Best regards
