I upgraded my storage server this morning from 5.5 to 5.6 and have quite
a few issues with servers attaching to the iSCSI target...

1) Prior to the upgrade, I had our initiators configured with a username
and password with CHAP and after the reboot I began having issues
mounting their LUN.  Looking through the logs I see:
CHAP initiator auth.: authentication of
iqn.2011-03.com.millbrookprinting.server:01:9386dd56f7d failed (wrong
secret!?)

Taking out the username and password and reattaching to the target works
fine.

2) One server is particular has a 2TB LUN assigned to it and cannot
mount it; which worked previously.

May  6 10:55:29 server kernel: sdc : very big device. try to use READ
CAPACITY(16).
May  6 10:55:29 server kernel: sdc : unsupported sector size 1229280288.
May  6 10:55:29 server kernel: SCSI device sdc: 0 512-byte hdwr sectors
(0 MB)

I see in some of the forums that downgrading the software "should" fix
the issue?

Packages are:
libibverbs-1.1.3-2.el5
openib-1.4.1-5.el5
librdmacm-1.0.10-1.el5
scsi-target-utils-1.0.8-0.el5_6.1

Kernel: 2.6.18-238.9.1.el5
64bit
CentOS 5.6

Thanks,
Jason
