Owners Manual

The following example illustrates potential Fluid Cache interfaces on Mellanox network adapters:
p6p2: <BROADCAST, MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000 link/
ether a0:36:9f:14:12:a2 brd ff:ff:ff:ff:ff:ff
3. Check that you have the required OFED package installed by running the command: ofed_info
4. Make sure the firmware and driver versions on each of these interfaces by running the command:
ethtool -i <interface name>
The firmware and driver must use supported versions as documented in the Release Notes.
The firmware and driver must use supported versions, as in this example:
driver: mlx4_en
version: 2.6.8 (Aug 18 2013)
firmware-version: 2.30.5118
5. Configure all interfaces for the management interface, the cache network, and potentially the iSCSI
network.
6. Ping the management interface and cache network addresses from all nodes. To install Fluid Cache,
you must be able to ping the management interface and cache network of every node in the cluster
from each node in the cluster.
To download updated firmware or drivers, see Downloading Firmware, Drivers, and Software.
Checking iSCSI Status
If the backing store is iSCSI, make sure that you have logged in to your iSCSI targets by running these
commands:
service iscsi status
service iscsid status
In the output text, make sure that the state of the iSCSI hosts is displayed as running.
Checking Storage Center Connectivity
Make sure that the node can see the storage, specifically the Dell Compellent LUNs, by running this
command: cat /proc/scsi/scsi
You must see results similar to the following (abbreviated in this example):
