Tru64 UNIX host volumes
General
•
The replication manager displays information about UFS, AdvFS host volumes and LSM logical
volumes on enabled hosts.
•
In a host cluster, only the volumes on the cluster's enabled host are displayed. See Enabled
hosts .
•
Local replication of UFS and AdvFS host volumes is supported. Local replication of LSM logical
volumes is not supported. See
Local replication .
Mounting
•
The replication manager does not support mounting a Tru64 host volume in a subdirectory of
/tmp.
Types
Virtual disks types reported by the replication manager:
Remarks Icon Type
Empty disks (disk space) that are preallocated for later use.
See
Containers .
Container
Dependent virtual disks that use mirrorclone technology.
See
Synchronized mirrorclones and Fractured mirrorclones .
Mirrorclone
Independent virtual disks, including snapclones.
See snapclones. Original
Dependent virtual disks that use snapshot technology.
See snapshots. Snapshot
Virtual disk guidelines
The following apply to virtual disks and containers.
•
Names. Up to 32 characters long. Names are not case sensitive but are subject to character
restrictions. See
Illegal characters .
•
Size. When creating, the size must be specified in whole GBs (no decimals).
NOTE: Some versions of controller software support virtual disks larger than 2 TB. The
following considerations apply to virtual disks larger than 2 TB:
◦ Local replication (snapshots, snapclones, mirrorclones) cannot be used with them.
◦ They cannot be a member of an HP P6000 Continuous Access remote replication group.
◦ DC-Management cannot be used to expand or shrink them.
