HP XP External Storage Software 4C External Storage
If you use this mode when the XP24000/XP20000 storage system is being used
as an external storage of another XP24000/XP20000 storage system, the data
of the MF-VOL in the storage system can be transferred. See the emulation types
below for the MF-VOL.
The data of the MF-VOL cannot be transferred when the storage systems are
connected with the host mode other than 4C External Storage, and the message
to require formatting is displayed after the mapping.
Cancel the message to require formatting, and set the host mode to 4C External
Storage to transfer data.
The volume data of the following emulation type can be transferred.

If you register VMware server hosts in a host group, you need to ensure that the host mode of the host group is 01
VMware or 21 VMware Extension.
If the host mode of a host group is 01 VMware and an LU path is defined between the host group and a logical volume,
you cannot combine the logical volume with other logical volumes to form a LUSE volume (that is, an expanded LU).
If the host mode of a host group is 21 VMware Extension and an LU path is defined between the host group and a logical
volume, the logical volume can be combined with other logical volumes to form a LUSE volume (i.e., an expanded LU).
If you plan to expand LUs by using LUSE in the future, set the host mode 21 VMware Extension. For detailed information
about LUSE, see theHP XP24000/XP20000 LUN Expansion User Guide.
2 If you register Windows server hosts in a host group, you need to ensure that the host mode of the host group is 0C
Windows or 2C Windows Extension.
If the host mode of a host group is 0C Windows and an LU path is defined between the host group and a logical volume,
the logical volume cannot be combined with other logical volumes to form a LUSE volume (i.e., an expanded LU).
If the host mode of a host group is 2C Windows Extension and an LU path is defined between the host group and a
logical volume, the logical volume can be combined with other logical volumes to form a LUSE volume (i.e., an expanded
LU). If you plan to expand LUs by using LUSE in the future, set the host mode 2C Windows Extension. For detailed
information about LUSE, see the HP XP24000/XP20000 LUN Expansion User Guide.
Besides the host modes mentioned above, the Host Mode list displays the Reserve host mode. Do
not select this host mode.
