OCF_HEARTBEAT_ISCSIL(7) OCF resource agents OCF_HEARTBEAT_ISCSIL(7)

ocf_heartbeat_iSCSILogicalUnit - Manages iSCSI Logical Units (LUs)

iSCSILogicalUnit [start | stop | status | monitor | meta-data | validate-all]

Manages iSCSI Logical Unit. An iSCSI Logical unit is a subdivision of an SCSI Target, exported via a daemon that speaks the iSCSI protocol.

implementation
The iSCSI target daemon implementation. Must be one of "iet", "tgt", "lio", or "lio-t". If unspecified, an implementation is selected based on the availability of management utilities, with "iet" being tried first, then "tgt", then "lio", then "lio-t".
(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.
(unique, optional, string, default "RESOURCE_ID")
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.
(unique, optional, string, no default)
emulate_tpu
The SCSI UNMAP command to be configured for this Logical Unit. Setting this integer to 1 will enable TPU IOCTL emulation.
(optional, integer, no default)
emulate_3pc
The SCSI EXTENDED COPY command to be configured for this Logical Unit. Setting this integer to 1 will enable 3PC IOCTL emulation.
(optional, integer, no default)
emulate_caw
The SCSI Compare and Write command to be configured for this Logical Unit. Setting this integer to 1 will enable CAW IOCTL emulation.
(optional, integer, no default)
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)
tgt_bstype
TGT specific backing store type. If you want to use aio, make sure your tgtadm is built against libaio. See tgtadm(8).
(optional, string, no default)
tgt_bsoflags
TGT specific backing store open flags (direct|sync). See tgtadm(8).
(optional, string, no default)
tgt_bsopts
TGT specific backing store options. See tgtadm(8).
(optional, string, no default)
tgt_device_type
TGT specific device type. See tgtadm(8).
(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)
allowed_initiators
Allowed initiators. A space-separated list of initiators allowed to connect to this lun. Initiators may be listed in any syntax the target implementation allows. If this parameter is empty or not set, access to this lun will not be allowed from any initiator, if target is not in demo mode.
This parameter is only necessary when using LIO.
(optional, string, no default)
lio_iblock
LIO iblock device name, a number starting from 0.
Using distinct values here avoids a warning in LIO "LEGACY: SHARED HBA"; and it is necessary when using multiple LUNs started at the same time (eg. on node failover) to prevent a race condition in tcm_core on mkdir() in /sys/kernel/config/target/core/.
(optional, integer, default 0)

This resource agent supports the following actions (operations):
start
Starts the resource. Suggested minimum timeout: 10s.
stop
Stops the resource. Suggested minimum timeout: 10s.
status
Performs a status check. Suggested minimum timeout: 10s. Suggested interval: 10s.
monitor
Performs a detailed status check. Suggested minimum timeout: 10s. Suggested interval: 10s.
meta-data
Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5s.
validate-all
Performs a validation of the resource configuration. Suggested minimum timeout: 10s.

The following is an example configuration for a iSCSILogicalUnit resource using the crm(8) shell:
primitive p_iSCSILogicalUnit ocf:heartbeat:iSCSILogicalUnit \
  params \
    target_iqn= string \
    lun= integer \
    path= string \
  op monitor timeout="10s" interval="10s" depth="0" 

The following is an example configuration for a iSCSILogicalUnit resource using pcs(8)
pcs resource create p_iSCSILogicalUnit ocf:heartbeat:iSCSILogicalUnit \
  target_iqn= string \
  lun= integer \
  path= string \
  op monitor timeout="10s" interval="10s" depth="0"
