SAN-based host volumes are displayed in the Host Volumes content pane and can represent storage
with a fi le system, or raw storage. Storage with a fi le system can be mounted or unmounted. See
host volumes views .
You can use a GUI action, a job, or CLUI command to mount and unmount SAN-based host volumes. You
can also locally replicate them using a job with the appropriate host volume commands.
Non-SAN-based host volumes
Non-SAN-based host volumes, such as fl oppy drives, CDs, and internal hard drives, are also discovered
and displayed in the Host Volumes content pane. You cannot use the replication manager to interact
with these non-SAN-based host volumes.
Network volumes
Depending on the host OS, the replication manager may or may not discover network volumes on
an enabled host.
Host volumes FAQ
• With host volumes, what does the
replicable
property indicate?
The replicable property indicates whether you can locally replicate a host volume. If snapclones
or snapshots are indicated, you can replicate the host volume
• How do I locally replicate a host volume?
Host volumes are replicated by using a GUI action or a job with the appropriate host volume
commands. You cannot locally replicate a host volume by using a CLUI command.
• What is the advantage in replicating a host volume rather than a storage volume (virtual disk)?
The main advantage is simplicity. When you use a job to specify the host volume to replicate, the
replication manager automatically determines the underlying storage systems and virtual disks
that are involved and issues the required low level replication commands via the job.
• Why can’t I locally replicate a speci fi c host volume?
When replicable property is N/A or No, a host volume cannot be locally replicated. This occurs
when the underlying physical storage for a host volume is not on an HP StorageWorks storage
system or the storage system is not licensed for local replication. See local replication licensing .
In some cases, local replication is not possible because the underlying virtual disks do not comply
with local replication guidelines. See virtual disk snapclone guidelines and snapshot guidelines .
