The stmfadm command configures logical units within the SCSI Target Mode Framework (STMF) framework. The framework and this man page use the following terminology: initiator A device responsible for issuing SCSI I/O commands to a SCSI target and logical unit. target A device responsible for receiving SCSI I/O commands for a logical unit. logical unit A device within a target responsible for executing SCSI I/O commands. logical unit number The identifier of a logical unit within a target. initiator group An initiator group is a set of one or more initiators that are combined for the purposes of being applied to a view (see below). An initiator cannot be a member of more than one initiator group. target group A target group is a set of one or more SCSI target ports that are combined for the purposes of being applied to a view (see below). A target port cannot be a member of more than one target group. view A view defines the association of an initiator group, a target group, and a logical unit number with a specified logical unit. Any view entry added to a logical unit must not be in conflict with existing view entries for that logical unit. A view entry is considered to be in conflict when an attempt is made to duplicate the association of any given initiator, target and logical unit number. As an exam- ple, logical unit LU_0 has the following view entry associated with it: Logical Unit: LU_0 View Entry: 0 initiator group: HostA target group: All targets logical unit number: 32 If you attempted the following: # stmf add-view -n 31 -h HostA LU_0 ...the operation would return an error with a message indicating that the view entry is in conflict with one or more existing view entries. This conflict arises because the existing view entry, 0, already has mapped LU_0 to logical unit number 32 for the initiator group HostA. SUB-COMMANDS The stmfadm command supports the subcommands listed below. add-view [-n, --lun logical-unit-number -t, --target-group group-name -h, --host-group group-name] lu-name Adds a logical unit view entry to a logical unit lu-name, where lu-name is the STMF name for the logical unit as displayed by the list- lu subcommand. The add-view subcommand provides the user with a mechanism to implement access control for a logical unit and also pro- vides a means of assigning a logical unit number to a logical unit for a given set of initiators and targets. A logical unit will not be available to any initiators until at least one view is applied. Each view entry gets assigned an entry name, which can be used to reference the entry in the remove-view and list-view subcommands. add-view supports the following options: -n, --lun logical-unit-number logical-unit-number is an integer in the range 0-16383 to be assigned to the logical unit for this view entry. If this option is not specified, a logical unit number will be assigned by the STMF framework. -t, --target-group group-name group-name is the name of a target group previously created using the STMF create-tg subcommand. If this option is not specified, the logical unit will be available through all targets. -h, -host-group group-name group-name is the name of an host group previously created using the STMF create-hg subcommand. If this option is not specified, the logical unit will be available to all initiators that log in to the STMF framework. add-hg-member -g group-name group member... Add a host group member to a host group. group-name must be an existing group created using the create-hg subcommand. group member can be specified as name_type.name_value, where name_type can be one of the following: wwn iqn eui ...and name_value is the value of the initiator name. As an example, to add a fibre channel initiator port world-wide name 200000e08b909221 to the host group HostA, the command would be: # stmfadm add-hg-member -g HostA wwn.200000e08b909221 To add an ISCSI initiator node member with the name iqn.1986-03.com.sun:01.46f7e262 to HostA, the command would be: # stmfadm add-hg-member -g HostA iqn.1986-03.com.sun:01.46f7e262 Alternatively, members can be specified using their SCSI name string identifiers. To add the two initiators above using their SCSI name string identifiers, the commands would be: # stmfadm add-hg-member -g HostA eui.200000e08b909221 # stmfadm add-hg-member -g HostA iqn.1986-03.com.sun:01.46f7e262 A host group member cannot be a member of more than one host group. add-tg-member -g group-name group member... Add a target group member to a target group. group-name must be an existing group created using the create-tg subcommand. group member can be specified as name_type.name_value, where name_type can be one of the following: wwn iqn eui ...and name_value is the value of the target name. As an example, to add a fibre channel target port world-wide name 501000e092376af7 to the target group TG0, the command would be: # stmfadm add-tg-member -g TG0 wwn.501000e092376af7 To add an ISCSI target member with the name iqn.1986-03.com.sun:target.01.01110 to TG0, the command would be: # stmfadm add-tg-member -g TG0 iqn.1986-03.com.sun:target.01.01110 Alternatively, members can be specified using their SCSI name string identifiers. To add the two targets above using their SCSI name string identifiers, the commands would be: # stmfadm add-tg-member -g TG0 eui.501000e092376af7 # stmfadm add-tg-member -g TG0 iqn.1986-03.com.sun:target.01.01110 A target group member cannot be a member of more than one target group. create-hg group-name Create an initiator group with the name group-name. group-name is a string of Unicode characters with a maximum length of 255. The group name must be unique within the STMF system. create-tg group-name Create a target group with the name group-name. group-name is a string of Unicode characters with a maximum length of 255. The group name must be unique within the STMF system. delete-hg group-name Delete the host group that identified by group-name. delete-tg group-name Delete the target group that identified by group-name. list-hg [-v,--verbose] [host-group-name...] Lists information for the host group in the system referenced by host-group-name. If host-group-name is not specified, all host groups in the system will be listed. If the --v or --verbose option is specified, all members within a host group are displayed. list-target [-v,--verbose] [target-name...] Lists information for the target port in the system referenced by target-name. If target name is not specified, all target ports in the system will be listed. If the -v or --verbose option is specified, additional information about the target along with SCSI session information for logged-in initiators is displayed. list-tg [-v,--verbose] [target-group-name...] Lists information for the target group in the system referenced by target-group-name. If target-group-name is not specified, all tar- get groups in the system will be listed. If the --v or --verbose option is specified, all members within a target group are displayed. list-lu [-v,--verbose] [lu-name...] Lists information for the logical unit in the system referenced by lu-name. If lu-name is not specified, all logical units in the sys- tem will be listed. If the -v or --verbose option is specified, additional information about the logical unit will be displayed. list-view --l, --lu-name lu-name [entry-name...] Lists the view entry for the logical unit referenced by lu-name. If entry-name is not specified, all view entries for the specified logical unit will be listed. list-state Lists the operational and configuration state of the STMF. remove-hg-member -g group-name group member Removes a host group member from a host group. group-name must be an existing group created using the create-hg subcommand. group mem- ber can be specified as name_type.name_value, where name_type can be one of the following: wwn iqn eui ...and name_value is the value of the initiator name. As an example, to remove the fibre channel initiator port world-wide name 200000e08b909221 from the host group HostA, the command would be: # stmfadm remove-hg-member -g HostA wwn.200000e08b909221 To remove the ISCSI initiator node member with the name iqn.1986-03.com.sun:01.46f7e262 from HostA, the command would be: # stmfadm remove-hg-member -g HostA iqn.1986-03.com.sun:01.46f7e262 Alternatively, members can be specified using their SCSI name string identifiers. To remove the two initiators above using their SCSI name string identifiers, the commands would be: # stmfadm remove-hg-member -g HostA eui.200000e08b909221 # stmfadm remove-hg-member -g HostA iqn.1986-03.com.sun:01.46f7e262 remove-tg-member -g group-name group member Removes a target group member from a target group. group-name must be an existing group created using the create-tg subcommand. group member can be specified as name_type.name_value, where name_type can be one of the following: wwn iqn eui ...and name_value is the value of the target name. As an example, to remove the fibre channel target port world-wide name 501000e092376af7 from the target group TG0, the command would be: # stmfadm remove-tg-member -g TG0 wwn.501000e092376af7 To remove the ISCSI target member with the name iqn.1986-03.com.sun:target.01.01110 from TG0, the command would be: # stmfadm remove-tg-member -g TG0 iqn.1986-03.com.sun:target.01.01110 Alternatively, members can be specified using their SCSI name string identifiers. To remove the two targets above using their SCSI name string identifiers, the commands would be: # stmfadm remove-tg-member -g TG0 eui.501000e092376af7 # stmfadm remove-tg-member -g TG0 iqn.1986-03.com.sun:target.01.01110 remove-view --l, --lu-name lu-name entry-name Removes one or more logical unit view entries from a logical unit.
