Configuring iSCSI Login Keys

In accordance with the iSCSI protocol, an iSCSI initiator must negotiate iSCSI login keys with each iSCSI

target to:

— enable an iSCSI connection

— authenticate the parties

— negotiate the session’s parameters

— mark the connection as belonging to an iSCSI session

All of the iSCSI login keys configured by default by the iSCSI Software Initiator apply to all of the targets

connected to the iSCSI host node. Currently, there are three iSCSI login keys that may be configured by the

user on a per target basis.

The three user configurable login keys are:

HeaderDigest

DataDigest

AuthMethod (Authentication Method)

The default value for HeaderDigest is:

None,CRC32C

The default value for DataDigest is:

None,CRC32C

The default value for AuthMethod is:

None

The user configurable login keys may be configured in one of the following ways:

— For all targets on a global basis

— For a particular Operational target.

— For a particular Discovery or Operational target address.

NOTE A login key configured for all targets, applies to all targets and all target addresses that are not

already configured for that login key.

A login key configured for a particular Operational target will apply to all Operational target

addresses that are not already configured for that login key.

Unique iSCSI Sessions are opened for each Operational target address. The login keys

configured for a particular Operational target address correspond to the unique iSCSI Session

opened on that Operational target address.

The usage to configure the login values for the user configurable login keys is as follows:

# iscsiutil [iscsi-device-file] -t <login-key> <login-val-1> <login-val-2> ...

<login-val-N> [-T <target-name> [-I <ip-address>] [-P <tcp-port>]
