= Configuring the RAID
|
|
|
|
The following procedure configures a redundant array of independent disks (RAID) using baseboard management controllers (BMCs) during the installation process.
|
|
|
|
[NOTE]
|
|
====
|
|
If you want to configure a hardware RAID for the node, verify that the node has a supported RAID controller. {product-title} {product-version} does not support software RAID.

.Hardware RAID support by vendor

[options="header"]

|
|
|Vendor | BMC and protocol |Firmware version|RAID levels
|
|
|Fujitsu | iRMC |N/A|0, 1, 5, 6, and 10
|
|
|Dell | iDRAC with Redfish | Version 6.10.30.20 or later | 0, 1, and 5

.Procedure
|
|
|
|
. Create the manifests.
|
|
|
|
. Modify the `BareMetalHost` resource corresponding to the node:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ vim clusterconfigs/openshift/99_openshift-cluster-api_hosts-*.yaml
|
|
----
|
|
+
|
|
[NOTE]
|
|
====
|
|
The following example uses a hardware RAID configuration because {product-title} {product-version} does not support software RAID.
|
|
====
|
|
+
|
|
.. If you added a specific RAID configuration to the `spec` section, this causes the node to delete the original RAID configuration in the `preparing` phase and perform a specified configuration on the RAID. For example:
|
|
+
|
|
[source,yaml]
|
|
----
|
|
spec:
|
|
raid:
|
|
hardwareRAIDVolumes:
|
|
- level: "0" <1>
|
|
name: "sda"
|
|
numberOfPhysicalDisks: 1
|
|
rotational: true
|
|
sizeGibibytes: 0
|
|
----
|
|
<1> `level` is a required field, and the others are optional fields.
|
|
+
|
|
.. If you added an empty RAID configuration to the `spec` section, the empty configuration causes the node to delete the original RAID configuration during the `preparing` phase, but does not perform a new configuration. For example:
|
|
+
|
|
[source,yaml]
|
|
----
|
|
spec:
|
|
raid:
|
|
hardwareRAIDVolumes: []
|
|
----
|
|
+
|
|
.. If you do not add a `raid` field in the `spec` section, the original RAID configuration is not deleted, and no new configuration will be performed.
|
|
|
|
. Create the cluster.
