ISCSI(4)						   BSD Kernel Interfaces Manual 						  ISCSI(4)

NAME
iscsi -- iSCSI initiator SYNOPSIS
To compile this driver into the kernel, place the following line in the kernel configuration file: device iscsi Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): iscsi_load="YES" DESCRIPTION
The iscsi subsystem provides the kernel component of an iSCSI initiator. The initiator is the iSCSI client, which connects to an iSCSI tar- get, providing local access to a remote block device. The userland component is provided by iscsid(8) and both the kernel and userland are configured using iscsictl(8). The iscsi subsystem is responsible for implementing the "Full Feature Phase" of the iSCSI protocol. SYSCTL VARIABLES
The following variables are available as both sysctl(8) variables and loader(8) tunables: kern.iscsi.ping_timeout The number of seconds to wait for the target to respond to a NOP-Out PDU. In the event that there is no response within that time the session gets forcibly restarted. kern.iscsi.iscsid_timeout The number of seconds to wait for ctld(8) to establish a session. After that time iscsi will abort and retry. kern.iscsi.login_timeout The number of seconds to wait for a login attempt to succeed. After that time iscsi will abort and retry. kern.iscsi.maxtags The maximum number of outstanding IO requests. kern.iscsi.fail_on_disconnection Controls the behavior after an iSCSI connection has been dropped due to network problems. When set to 1, a dropped connection causes the iSCSI device nodes to be destroyed. After reconnecting, they will be created again. By default, the device nodes are left intact. While the connection is down all input/output operations are suspended, to be retried after the connection is reestablished. SEE ALSO

OCF_HEARTBEAT_ISCSI(7)						OCF resource agents					    OCF_HEARTBEAT_ISCSI(7)

NAME
ocf_heartbeat_iscsi - Manages a local iSCSI initiator and its connections to iSCSI targets SYNOPSIS
iscsi [start | stop | status | monitor | meta-data | validate-all] DESCRIPTION
OCF Resource Agent for iSCSI. Add (start) or remove (stop) iSCSI targets. SUPPORTED PARAMETERS
portal The iSCSI portal address in the form: {ip_address|hostname}[":"port] (required, string, no default) target The iSCSI target IQN. (unique, required, string, no default) discovery_type Target discovery type. Check the open-iscsi documentation for supported discovery types. (optional, string, default sendtargets) iscsiadm open-iscsi administration utility binary. (optional, string, default iscsiadm) udev If the next resource depends on the udev creating a device then we wait until it is finished. On a normally loaded host this should be done quickly, but you may be unlucky. If you are not using udev set this to "no", otherwise we will spin in a loop until a timeout occurs. (optional, string, default yes) SUPPORTED ACTIONS
This resource agent supports the following actions (operations): start Starts the resource. Suggested minimum timeout: 120. stop Stops the resource. Suggested minimum timeout: 120. status Performs a status check. Suggested minimum timeout: 30. monitor Performs a detailed status check. Suggested minimum timeout: 30. Suggested interval: 120. validate-all Performs a validation of the resource configuration. Suggested minimum timeout: 5. methods Suggested minimum timeout: 5. meta-data Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5. EXAMPLE
The following is an example configuration for a iscsi resource using the crm(8) shell: primitive p_iscsi ocf:heartbeat:iscsi params portal=string target=string op monitor depth="0" timeout="30" interval="120" SEE ALSO
