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-probe command to determine the global device path of the HBA LUN. sr-probe forces 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-uuid parameter 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:device parameter 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.
