HP XP Array Manager Software - Manual (Page 39)

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, you cannot combine the logical volume with other logical volumes to
form a LUSE volume (that is, an expanded LU). For detailed information about LUSE, see the HP
StorageWorks XP24000 LUN Expansion User’s Guide.
• 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 you are thinking about creating
LUSE volumes (that is, expanded LUs), you should consider setting the host mode 21 VMware
Extension to the host group.
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). For detailed information about LUSE, see the HP
StorageWorks XP24000 LUN Expansion User’s Guide.
• Besides the host modes mentioned above, the Host Mode drop-down list displays the Reserve host
mode. Do not select this host mode.

VERITAS Database Edition/
Advanced Cluster
When VERITAS Database Edition/Advanced Cluster for
Real Application Clusters or VERITAS Cluster Server 4.0
(I/O fencing function) is used
6 TPRLO
When all the following conditions are satisfied:
• The host mode 0C Windows or 2C Windows Extension
is used
• The Emulex host bus adapter is used
• The mini-port driver is used
• TPRLO=2 is specified for the mini-port driver parameter
of the host bus adapter

Automatic recognition function of
LUN
When all the following conditions are satisfied:
• The host mode 00 Standard or 09 Solaris is used
• SUN StorEdge SAN Foundation Software Version 4.2
or better is used
• You want to automate recognition of increase and
decrease of devices when genuine SUN HBA is
connected
12 No display for ghost LUN
When all the following conditions are satisfied:
• The host mode 03 HP is used
• You want to suppress creation of device files for devices
to which paths are not defined.
13 SIM report at link failure
When the user want to be informed by SIM (service
information message) that the number of link failures
detected between ports exceeds the threshold
Registering Hosts in Host Groups
To set LU paths, you must register hosts in host groups. For example, if HP-UX hosts and Widows hosts
are connected to a port, you must register HP-UX hosts and Windows hosts separately in two different
host groups.
When registering a host, you are requested to specify the WWN of the host bus adapter. If you are
unsure of WWNs of your host bus adapters, see Appendix A.
When registering a host, you can assign a nickname to the host bus adapter. If you assign a nickname,
you will be able to easily identify each host bus adapter in the LUN Manager window. Although WWNs
are also used to identify each host bus adapter, the nickname that you assign will be more helpful
because you can name host bus adapters after the host installation site or the host owners.
