NAME
iscsi.conf —
iSCSI initiator configuration
file
DESCRIPTION
The iscsi.conf configuration file is used
by the
iscsictl(8) utility. The general syntax is:
# this is a comment
nickname_1 {
variable = value;
...
}
nickname_2 {
variable = value;
...
}
...
AuthMethod- Sets the authentication type. Type can be either
"None", or
"CHAP". Default is
"None". When set to
CHAP, bothchapINameandchapSecretmust be defined. chapIName- Login for CHAP authentication.
chapSecret- Secret for CHAP authentication.
tgtChapName- Target login for Mutual CHAP authentication.
tgtChapSecret- Target secret for Mutual CHAP authentication.
HeaderDigest- Sets the header digest; a checksum calculated over the header of iSCSI PDUs, and verified on receive. Digest can be either "None", or "CRC32C". Default is "None".
DataDigest- Sets the data digest; a checksum calculated over the Data Section of iSCSI PDUs, and verified on receive. Digest can be either "None", or "CRC32C". Default is "None".
InitiatorName- Sets the initiator name. By default, the name is concatenation of "iqn.1994-09.org.freebsd:" with the hostname.
TargetName- Sets the target name. Not required for discovery sessions.
TargetAddress- Sets the target address and port, in address[:port] format. The address can be either an IP address, or hostname. The optional port defaults to 3260.
SessionType- Sets the session type. Type can be either "Discovery", or "Normal". Default is "Normal". For normal sessions, the TargetName must be defined. Discovery sessions result in the initiator connecting to all the targets returned by SendTargets iSCSI discovery with the defined TargetAddress.
Enable- Enable or disable the session. State can be either "On", or "Off". Default is "On".
Offload- Name of selected iSCSI hardware offload driver. Default is "None".
Protocol- Name of selected protocol. It can be either "iSER", for iSCSI over RDMA, or "iSCSI". Default is "iSCSI".
dscp- The DiffServ Codepoint used for sending data. The DSCP can be set to numeric, or hexadecimal values directly, as well as the well-defined "cs<n>" and "af<xx>" codepoints. Default is no specified dscp codepoint, which means the default of the outgoing interface is used.
pcp- The 802.1Q Priority CodePoint used for sending packets. The PCP can be set to a value in the range between "0" to "7". When omitted, the default for the outgoing interface is used.
PingTimeout- Specify the time in seconds to wait between pings (SCSI NOP), and for a ping response before declaring the session as dead and attempting a re-establishment. If this entry is not present in the conf file, the default value configured using "kern.iscsi.ping_timeout" (default at "5" seconds) is taken by the driver. If present, the PingTimeout can be set to any positive value starting with "1".
LoginTimeout- Specify the time in seconds to wait for a login PDU to be sent or received after trying to establish a new session. When no login PDU is received within this time, the login on a particular connection fails and a new reconnection attempt is made. If this entry is not present in the conf file, the default value of "60" seconds is used, as configured by "kern.iscsi.login_timeout". The LoginTimeout can be set to any positive value starting with "1".
