5.

Repeat step 4 on every host.

6.

On the storage server, run this command to get a unique ID for the new SR.

# uuidgen

The output should look like this, although the specific ID will be different:

e6849e96-86c3-4f2c-8fcc-350cc711be3d

7.

Create the FiberChannel SR. In name-label, use the unique ID you just generated.

# xe sr-create type=lvmohba shared=true

device-config:SCSIid=360a98000503365344e6f6177615a516b

name-label="e6849e96-86c3-4f2c-8fcc-350cc711be3d"

This command returns a unique ID for the SR, like the following example (your ID will be different):

7a143820-e893-6c6a-236e-472da6ee66bf

8.

To create a human-readable description for the SR, use the following command. In uuid, use the
SR ID returned by the previous command. In name-description, set whatever friendly text you
prefer.

# xe sr-param-set uuid=7a143820-e893-6c6a-236e-472da6ee66bf name-description="Fiber

 Channel storage repository"

Make note of the values you will need when you add this storage to CloudPlatform later (see

will choose PreSetup. In SR Name-Label, you will enter the name-label you set earlier (in this
example, e6849e96-86c3-4f2c-8fcc-350cc711be3d).

9.

(Optional) If you want to enable multipath I/O on a FiberChannel SAN, refer to the documentation
provided by the SAN vendor.

When setting up the storage repository on a Citrix XenServer, you can enable multipath I/O, which
uses redundant physical components to provide greater reliability in the connection between the
server and the SAN. To enable multipathing, use a SAN solution that is supported for Citrix servers
and follow the procedures in Citrix documentation. The following links provide a starting point:

You can also ask your SAN vendor for advice about setting up your Citrix repository for multipathing.
