HP XP P9500 Storage - Manual (Page 157)

When to select this mode Host mode
When registering AIX server hosts in the host group 0F AIX
When registering VMware server hosts in the host group (See Note) 21 VMware Extension
When registering Windows server hosts in the host group (See Note) 2C Windows Extension
When registering another P9500 storage system in the host group for mapping by using
External Storage. 4C UVM
If this mode is used when the P9500 storage system is being used as an external storage
system of another P9500 storage system, the data of the MF-VOL in the P9500 storage
system can be transferred. Refer to 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 UVM, and a message requiring formatting appears
after the mapping. In this case, cancel the message requiring formatting, and set the host
mode to 4C UVM when you want to transfer data.
The volume data of the following emulation type can be transferred: 3390-3A, 3380-3A,
3390-9A, 3390-LA.
CAUTION: Note the following when setting the host mode.
•
If Windows server hosts are registered in a host group, 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 (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 (that is, an expanded LU). If you plan to expand LUs by using
LUSE in the future, set the host mode 2C Windows Extension.
•
If VMware server hosts are registered in a host group, 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, the logical volume cannot be combined 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 (that is, an expanded LU). If you plan to expand LUs by using
LUSE in the future, set the host mode 21 VMware Extension.
