•
Extending a host volume is supported on Windows 2003 and Windows Server 2008.
•
Shrinking a host volume is supported on Windows Server 2008, but only on basic disks and
dynamic simple volumes that are spanned or are mirrors. Striped or Vraid5 dynamic disks do
not support shrink.
•
Supported file systems include NTFS. MBR and GPT partitions are supported. Replication and
DC-Management of Windows dynamic disks and VERITAS Volume Manager are not supported.
HP-UX requirements and considerations
•
HP-UX 11.31 and 11.23 host agents support DC-Management. The following table identifies
the DC-Management features supported for different HP-UX configurations.
•
DC-Management policies are supported only for single virtual disk host volumes.
•
All offline resize operations must be performed using the manual DC-Management feature.
Automatic DC-Management policies can only be used to perform an online resize.
•
When taking a host volume offline to perform a resize operation, all other host volumes that
are part of same volume group must also be unmounted. Before performing a resize, stop I/O
on all host volumes and close all open files so that RSM can take the host volumes offline.
After completion of the resize operation, all host volumes will be mounted and you can resume
I/O.
