lost iscsi-targets after update firmware 3.00.08b

[xxlsteffen]

After upgrading firmware the names of my iscsi-targets are lost. I am not able to alter the iscsi-targets which are empty via webinterface. i did the following:
the update on version 3.00.08b was successful but the machine was inaccessible on webinterface and iscsi. I downgraded to version 2.01.09. In Version 2.01.09 i reimported my old config.
Altering the iscsi-Targets was unsuccessful.

1. Storage / Page Allocation: i choose an iscsi-target without name and press "modify"
2. "Space Allocation"-window appaers everything is empty the target is disabled
3 i fill in values and enable the target
4 i press "OK"
5 system says: "database updated successfully"
6 nothing happened with the target

I tried Firmware Version 3.00.07a the thecus is running with it, but the problem appears in 2.01.09 and 3.00.07a

after installing the modules UTILS, SYSUSER and SSHD i played with the command ut_iscsi show and nothing appears. But i find under §/dev/vg0 my defined iscsi targets. To me that means that the Database is corrupted. Any Ideas how to fix this?

It seems nobody knows how to fix our problem. We found after days a solution with analysis the program.

to rebuild the Database you must modify raid.db and ietd.conf by hand

Steps

0. if you have place, create first one new iscsi target with the webinterface
1. install SSH and Sysuser Module
2. download WinSCP grafik SSH Client, winscp.net/eng/download.php and conect
3. navigate to /raid0/sys/
4. download the ietd.conf and raid.db if exist
6. navigate to raid1/sys/
7. download the ietd.conf and raid.db if exist
8. download the version 1.1 from sqlitebrowser sourceforge.net/projects/sqlitebrowser/files/sqlitebrowser/1.1/sqlitebrowser-1.1-win.zip/download
9. open the raid.db files this is a sqlite 2.1 database file with the sqlitebrowser
10. navigate in the winscp to /dev/vg0 and /dev/vg1

you should see iscsi0 until iscsiN N ... 0 - X number of Files
for each you need in the database one row -> for the vg0 in the raid.db from path raid0
and for the vg1 in the raid.db from path raid1

the ietd.conf exist only one on FW 2.01.09 maybe in the raid1 after flash firmeware the raid1 and raid0 moved with the 3.00.07a then the file stand in raid0 and the database was lost again ;-(

on the webinterface you should see the size of the iscsi0 file and the size of the disk,
you need it in percent iscsi0size/disksize*100 -> round for the database

f.e.
disk is 1959,2 the iscsi0 is 929 -> mean 50%
the raid.db struktur
"lvname","name","enabled","chap","user","pass","percent","comment","year","month","v1","v2","v3","v4 ","v5"
"iscsi0","yourname","1","0","","","50","","2010","01","","","","",""

open the raid.db files with the SQLite Database Browser

create for each iscsi0 -> iscsiN one row -> you should match the percent for each target
the year and the month must match the traget name later in the ietd.conf
-> iqn.year-month.domainname -> e.f. "iqn.2010-01.domainname:RAID.iscsi0.vg1.yourname"

domainname -> mean the network name from you firm this name should you know

now modify the ietd.conf
below is a sample, the Target must match your system, if you have first
create one new iscsi target, in the "ietd.conf" should like this sample
and for each lost iscsi target copy this block or your sample -> modify the "Target", "Lun" and "Path"
the "Lun" is a number, each number should used only one

use the file has only the "LF" in the end of a line, use f.e. notepad++ for to show all characters

--copy--
Target iqn.2010-01.domainname:RAID.iscsi0.vg1.yourname
Lun 0 Path=/dev/vg1/iscsi0,Type=fileio,IOMode=wb
MaxConnections 8
InitialR2T No
ImmediateData Yes
MaxRecvDataSegmentLength 262144
MaxXmitDataSegmentLength 262144
MaxBurstLength 262144
DefaultTime2Wait 2
DefaultTime2Retain 20
MaxOutstandingR2T 16
DataPDUInOrder No
DataSequenceInOrder Yes
ErrorRecoveryLevel 0
HeaderDigest None
DataDigest None
Wthreads 8

--copy end---

If you have the raid.db files one for each raid0 and raid1 and one ietd.conf file
then conect with SSH Putty conect and stop the service

/img/bin/rc/rc.iscsi stop

now copy the files raid.db and ietd.conf back on the thecus

restart the servcie
/img/bin/rc/rc.iscsi start

go to the web interface and if you have luck the targets has names now
