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

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

Device-config parameters for lvmohba SRs:

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: 

/bin/sbin/ocmanager

• QLogic FC: 

/opt/QLogic_Corporation/SANsurferCLI

• QLogic iSCSI: 

/opt/QLogic_Corporation/SANsurferiCLI

See 

 for an example of QLogic iSCSI HBA

configuration. For more information on Fibre Channel and iSCSI HBAs please refer to the 

 and 

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.
