Description

Optional?

chapuser	the username to be used for CHAP authentication	no
chappassword	the password to be used for CHAP authentication	no
port	the network port number on which to query the target	no
usediscoverynumber	the specific iscsi record index to use	no

To create a shared lvmoiscsi SR on a specific LUN of an iSCSI target use the following command.

xe sr-create host-uuid=<valid_uuid>content-type=user \ name-label=<"Example shared LVM over iSCSI SR"> shared=true \ device-config:target=<target_ip=>device-config:targetIQN=<target_iqn=>\ device-config:SCSIid=<scsci_id>\

type=lvmoiscsi

Creating a shared LVM over Fibre Channel / iSCSI HBA or SAS SR (lvmohba)

SRs of type lvmohba can be created and managed using the xe CLI or XenCenter.

Device-config parameters for lvmohba SRs:

Parameter name	Description	Required?
SCSIid	Device SCSI ID	Yes

To create a shared lvmohba SR, perform the following steps on each host in the pool:

1.Zone in one or more LUNs to each XenServer host in the pool. This process is highly specific to the SAN equipment in use. Please refer to your SAN documentation for details.

2.If necessary, use the HBA CLI included in the XenServer host to configure the HBA:

•Emulex: /usr/sbin/hbanyware

•QLogic FC: /opt/QLogic_Corporation/SANsurferCLI

•QLogic iSCSI: /opt/QLogic_Corporation/SANsurferiCLI

See the section called “Managing Hardware Host Bus Adapters (HBAs)” for an example of QLogic iSCSI HBA configuration. For more information on Fibre Channel and iSCSI HBAs please refer to the Emulex and QLogic websites.

3.Use the sr-probecommand to determine the global device path of the HBA LUN. sr-probeforces a re- scan of HBAs installed in the system to detect any new LUNs that have been zoned to the host and returns a list of properties for each LUN found. Specify the host-uuidparameter to ensure the probe occurs on the desired host.

The global device path returned as the <path> property will be common across all hosts in the pool and therefore must be used as the value for the device-config:deviceparameter when creating the SR.

If multiple LUNs are present use the vendor, LUN size, LUN serial number, or the SCSI ID as included in the <path> property to identify the desired LUN.
