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.

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.
