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

• Veritas file system (VxFS) is supported. HFS file system is not supported.
• The following resize operations are not supported when using LVM:
Extend logical volumes in native LVM Volume Groups with mirrored, striped, or contiguous
logical volumes.
◦
◦ Extend logical volumes in native LVM Volume Group when VG is cluster aware (activated
in shared or exclusive mode).
◦ Extend logical volumes in native LVM Volume Group using PV that is not allocatable
(includes spare PVs and PVs in read-only mode).

When performing a manual extend or shrink, the operation is executed immediately. No policy is created when performing
a manual operation.
2
If the host volume is not part of a volume group, taking it offline involves unmounting it. If the host volume is part of a
volume group, taking it offline involves unmounting it and deactivating the volume group.

Policies are supported only for single virtual disk host volumes.

Requires installation of the vgmodify tool. This tool is part of the HPUX patch PHCO_35524 for 11.23.
VMFS requirements and considerations
• Only extend is supported with VMFS.
• Support is provided only for host volumes on basic disks on VMFS volumes. Dynamic disks
are not supported.
• Support is provided only for host volumes created on LUNs from the same storage system.
Selecting the proper dynamic capacity policy thresholds
When setting a dynamic policy, the following guidelines apply:
• Use an extend threshold of 75% or greater.
• Use a shrink threshold of 35% or less.
• Use an increment value of approximately 10% of the current host volume size. For example,
if the current size is 50 GB use an increment value of 5 GB.
