20 Citrix XenServer with Dell SC Series Storage Configuration and Deployment | 3132-CD-V
xe pif-param-set other-config:mtu=9000 uuid=Pif-UUID
3. Repeat this process for each eth interface dedicated for iSCSI storage traffic on each XenServer host
connecting to the SC Series storage.
4.2.3.2 Required steps
Note: If Jumbo Frames are to be used, the steps in section 4.2.3.1 must be completed prior to executing the
following steps.
1. Ensure that the physical interface (PIF) is on a separate subnet or that routing is configured to suit
your network topology, forcing the desired traffic over the selected PIF.
2. Get the PIF UUID for the interface:
- For a standalone XenServer host: Execute xe pif-list to list the PIFs on the server.
- If the XenServer host is part of a pool:
i. Execute xe host-list to retrieve a list of the hosts and UUIDs.
ii. Execute xe pif-list host-uuid=host-uuid to list the PIFs on the selected host.
3. Set up an IP configuration for the PIF, adding appropriate values for the mode parameter, and if using
static IP addressing, add values for the IP, netmask, gateway (if required), and DNS parameters:
xe pif-reconfigure-ip mode=DHCP|static uuid=pif-uuid
Example: xe pif-reconfigure-ip mode=static ip=10.10.10.91
netmask=255.255.255.0 gateway=10.10.10.1 uuid=Pif-UUID
Note: When setting IP information for iSCSI connection, the gateway parameter is only required if iSCSI
traffic must route to another IP subnet and has access to the appropriate router.
4. Set the PIFs disallow-unplug parameter to true:
xe pif-param-set disallow-unplug=true uuid=Pif-UUID
5. Set the management purpose of the interface:
xe pif-param-set other-config:management_purpose="iSCSI-01" uuid=Pif-UUID
6. Disable automatic assignment of network to new VMs:
xe pif-param-set other-config:automatic="false" uuid=Pif-UUID
7. Repeat steps 3–6 for each eth interface dedicated for iSCSI storage traffic on each XenServer host
connecting to the SC Series storage. For iSCSI MPIO configurations, a minimum of two eth interfaces
on each XenServer host, on separate subnets is recommended.
Note: XE CLI uses xe pif to identify ethx devices where x identifies which device. The XenCenter
management GUI identifies the same devices with the NIC x designation, where x identifies which device.
While the designation differs (eth vs NIC), the x identifier is consistent between utilities.
