Disk Devices The replication manager uses the term host disk device to refer a host's identification of storage devices. With SAN-based storage resources, for each virtual disk that is presented to a host, there is a corresponding entry (identification) in a host's low-level devices table. The replication manager discovers these devices on enabled hosts and displays them in the Disk Devices tab on the Host Volumes content pane. See host volume views and viewing host volumes. File system types The file system property indicates whether a host volume is formatted with a file system or not. Examples of file system types: AdvFS. Tru64 UNIX ufs. AIX, HP-UX, Linux, Solaris, Tru64 UNIX vxfs. HP-UX NTFS. Windows Files-11, ODS-2, ODS-5. OpenVMS If a host volume is not formatted with a file system, the property displays raw disk information. See host volumes raw disks. Instant Restore The instant restore feature allows you to restore data on a host volume or host volume group with data from one of its previously created replicas (snapclone or snapshot). The operation is instant because the restored data is available within seconds for host I/O (the actual data transfer occurs in the background). For example, assume that the database named sales_db becomes corrupt. You can instantly restore it to a prior state from one of its replicas. sales_db
