Replace Boot Disk on a Host

This section describes the replacement procedure for a failed boot disk on a host.

Prerequisites

If the host is operational, verify that there are at least four hosts in the management domain or at least three hosts in a VI workload domain to which the faulty host belongs. If there are fewer than the required number of hosts, add a host to the workload domain from the free pool, if possible. If the host is not operational, see Replace a Dead Host.

Procedure

1. If there are dual boot disks in the host setup as RAID 1 and only one of them fails:
   • See Replacing Components of a Host Running in Degraded Mode to replace the failed disk.

   The RAID 1 feature will rebuild the disks as needed. For more details, refer to the OEM vendor documentation.

2. If there is a single boot disk in the host and it fails, see Replace a Dead Host.
