3200 - iSCSI not start normally

Hi!

I detect some problem with iSCSI on ReadyNAS 3200 with 4.2.22 firmware (I think, it present in previous version too):
1. I have several iSCSI-targets on NAS. My /etc/ietd.conf

Target iqn.2011-08.plt-nas.foo.ru:plt-dpm01
   Lun 0 Path=/c/.iscsi/plt-dpm01~0,Type=fileio,ScsiSN=RNA12YH04E6E-001,IOMode=wb
# desc plt-dpm01 0 DPM STORE
   HeaderDigest CRC32,None
   DataDigest CRC32,None
   IncomingUser opbackup ************

Target iqn.2011-08.plt-nas.foo.ru:plt-dpm02
   Lun 0 Path=/c/.iscsi/plt-dpm02~0,Type=fileio,ScsiSN=RNA12YH04E6E-004,IOMode=wb
# desc plt-dpm02 0 DPM-STORE02
   HeaderDigest CRC32,None
   DataDigest CRC32,None
   IncomingUser opbackup ************

Target iqn.2011-08.plt-nas.foo.ru:sap-iscsi
   Lun 0 Path=/c/.iscsi/sap-iscsi~0,Type=fileio,ScsiSN=RNA12YH04E6E-002,IOMode=wb
# desc sap-iscsi 0 SAP-iSCSI
   HeaderDigest CRC32,None
   DataDigest CRC32,None

Target iqn.2011-08.plt-nas.foo.ru:sys-bia
   Lun 0 Path=/c/.iscsi/sys-bia~0,Type=fileio,ScsiSN=RNA12YH04E6E-003,IOMode=wb
# desc sys-bia 0 sysbia
   HeaderDigest CRC32,None
   DataDigest CRC32,None

2. After rebooting NAS clients can't connect to second target. In logs I see error with CHAP auth.

How this problem solved:
1. I can set same password to target - client connect immediatly.
2. After restart I can restart iscsi-server -

/etc/init.d/iscsitarget stop
/etc/init.d/iscsitarget start

- client connect to target with no problem

So I think about problem with iSCSI initiation. It seem like wrong config in start time. Anybody know where initial conf located and how I can correct them?
