Login Key Configuration
Configuring iSCSI Login Keys
83
[-M <portal-grp-tag>]]
The order in which the login values are listed in this command defines the order in which the iSCSI initiator
proposes them to the target. The login keys and values are not case-sensitive.
The configurable login keys currently available are:
HeaderDigest
A header digest that can be negotiated during iSCSI login. The list of parameters that the HeaderDigest
key can accept are:
None
CRC32C
DataDigest
A data digest that can be negotiated during iSCSI login. The list of values that the DataDigest key can
accept are:
None
CRC32C
AuthMethod
An authentication method that can be negotiated during iSCSI login. The list of values that the
AuthMethod key can accept are:
None
CHAP
The order of precedence of login key configuration is as follows:
(a) iSCSI Target Address level
(b) iSCSI Target level
(c) Global level
Configuration of login keys at the Discovery target level is not possible, because Discovery targets are not
identified by iSCSI target names.
Configuration of login keys for Discovery target addresses does not involve defining the iSCSI target names.
For Operational targets (addresses), the target names should be defined.
NOTE One or two login key values may be specified for each of the login keys listed above, however, no
more than two login key values can be specified for a login key.
Header and Data Digest Configuration Examples
Configure the HeaderDigest key with "None,CRC32C" as the value for all targets:
# iscsiutil -t headerdigest None CRC32C
Configure the DataDigest key with "CRC32C,None" as the value for a particular Discovery Target Address
which is already configured:
# iscsiutil -t datadigest CRC32C None -I 192.1.1.58 -M 2
Configure the DataDigest key with "CRC32C,None" as the value for an Operational Target:
