Managing Disks in the Cluster
Disks, SSDs or HDDs, might fail. If this occurs, you need to remove the failed disk and replace it. Follow the server hardware instructions for removing and replacing the disks in the host. The HX Data Platform identifies the SSD or HDD and incorporates it into the storage cluster.
To increase the datastore capacity of a storage cluster add the same size and type SSDs or HDDs to each converged node in the storage cluster. For hybrid servers, add hard disk drives (HDDs). For all flash servers, add SSDs.
When performing a hot-plug pull and replace on multiple drives, pause for a few moments (30 seconds) between each action. Pull and replace a drive, pause, pull and replace the next drive.
Sometimes, when a disk is removed it continues to be listed in cluster summary information. To refresh this, restart the HX cluster.
