= Enabling multipathing with kernel arguments on {op-system}
{op-system-first} supports multipathing on the primary disk, allowing stronger resilience to hardware failure to achieve higher host availability. Postinstallation support is available by activating multipathing via the machine config.
[IMPORTANT]
====
Enabling multipathing during installation is supported and recommended for nodes provisioned in {product-title} 4.8 or higher. In setups where any I/O to non-optimized paths results in I/O system errors, you must enable multipathing at installation time. For more information about enabling multipathing during installation time, see "Enabling multipathing with kernel arguments on RHCOS" in the _Installing on bare metal_ documentation.

====
On {ibm-z-name} and {ibm-linuxone-name}, you can enable multipathing only if you configured your cluster for it during installation. For more information, see "Installing {op-system} and starting the {product-title} bootstrap process" in _Installing a cluster with z/VM on {ibm-z-name} and {ibm-linuxone-name}_.
