HP P6000 Replication Solutions Manager User Guide (T3680-96089, October 2012)

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.
