NAME
ocf_heartbeat_iSCSILogicalUnit - Manages iSCSI Logical Units (LUs)
SYNOPSIS
iSCSILogicalUnit [start | stop | monitor | meta-data | validate-all]
DESCRIPTION
Manages iSCSI Logical Unit. An iSCSI Logical unit is a subdivision of
an SCSI Target, exported via a daemon that speaks the iSCSI protocol.
SUPPORTED PARAMETERS
implementation
The iSCSI target daemon implementation. Must be one of "iet",
"tgt", or "lio". If unspecified, an implementation is selected
based on the availability of management utilities, with "iet" being
tried first, then "tgt", then "lio". (optional, string, no default)
target_iqn
The iSCSI Qualified Name (IQN) that this Logical Unit belongs to.
(required, string, no default)
lun
The Logical Unit number (LUN) exposed to initiators. (required,
integer, no default)
path
The path to the block device exposed. Some implementations allow
this to be a regular file, too. (required, string, no default)
scsi_id
The SCSI ID to be configured for this Logical Unit. The default is
the resource name, truncated to 24 bytes. (optional, string,
default default)
scsi_sn
The SCSI serial number to be configured for this Logical Unit. The
default is a hash of the resource name, truncated to 8 bytes.
(optional, string, default c21f969b)
vendor_id
The SCSI vendor ID to be configured for this Logical Unit.
(optional, string, no default)
product_id
The SCSI product ID to be configured for this Logical Unit.
(optional, string, no default)
additional_parameters
Additional LU parameters. A space-separated list of "name=value"
pairs which will be passed through to the iSCSI daemon's management
interface. The supported parameters are implementation dependent.
Neither the name nor the value may contain whitespace. (optional,
string, no default)
SUPPORTED ACTIONS
This resource agent supports the following actions (operations):
start
Starts the resource. Suggested minimum timeout: 10.
stop
Stops the resource. Suggested minimum timeout: 10.
monitor
Performs a detailed status check. Suggested minimum timeout: 10.
Suggested interval: 10.
meta-data
Retrieves resource agent metadata (internal use only). Suggested
minimum timeout: 5.
validate-all
Performs a validation of the resource configuration. Suggested
minimum timeout: 10.
EXAMPLE
The following is an example configuration for a iSCSILogicalUnit
resource using the crm(8) shell:
primitive example_iSCSILogicalUnit ocf:heartbeat:iSCSILogicalUnit \
params \
target_iqn=string \
lun=integer \
path=string \
op monitor timeout="10" interval="10" depth="0"
