Hello all, I'm running the iscsi-initiator-utils package v4.0.3.0
(included with RHEL4) and trying to link up to a 2TB LUN exported from
a RHEL5.2 machine using STGT (0.20070620snap).
The RHEL4 machine is running 32-bit while the RHEL5 machine is 64-bit.
When I log in to the target, I see the following in dmesg:
iscsi-sfnet:host2: Session established

sdb : very big device. try to use READ CAPACITY(16).
This means that the kernel wanted to treat the device as larger than 2TiB.
sdb : READ CAPACITY(16) failed.
It tried to send a READ CAPACITY (16) which is a 16-byte CDB. However,
the SCSI LLD that is the initiator has to set the size of the largest
CDBs it accepts, and the default is 12, as I recall.
It is 16 in RHEL 4.7 (I think we got this fixed in RHEL4 since .5).
