ISCSI target driver for SCST framework. The iSCSI protocol has been
|
|
defined in RFC 3720. To use it you should download from
|
|
http://scst.sourceforge.net the user space part of it.

Simulates iSCSI digest failures in random places. Even when iSCSI
|
|
traffic is sent over a TCP connection, the 16-bit TCP checksum is too
|
|
weak for the requirements of a storage protocol. Furthermore, there
|
|
are also instances where the TCP checksum does not protect iSCSI
|
|
data, as when data is corrupted while being transferred on a PCI bus
|
|
or while in memory. The iSCSI protocol therefore defines a 32-bit CRC
|
|
digest on iSCSI packets in order to detect data corruption on an
|
|
end-to-end basis. CRCs can be used on iSCSI PDU headers and/or data.
|
|
Enabling this option allows to test digest failure recovery in the
|
|
iSCSI initiator that is talking to SCST.
|

|
|
If unsure, say "N".
