Note: In WWNs, "X" is an arbitrary number or character. The ports in a physical storage system have the identical
value.
When the model of HUS/AMS/WMS storage system is changed, the WWN of the port is changed
as well. If the HUS/AMS/WMS storage system is used as an external storage system, the mapped
external path may be blocked. To correct this problem, you can delete the mapping of the external
path and remap it to use the blocked external path. See
“Requirements for external storage system
maintenance” (page 65) for detailed information on remapping.
Identifying logical volumes using Characteristic1
The Characteristic1 value is the internal LUN number of the LUNS from the AMS/WMS.
Caution on using the power savings option
When an HUS 150, HUS 130, HUS 110, AMS 2500, AMS 2300, AMS 2100, or AMS 2010
storage system is connected as an external system with the Power Savings option is enabled, do
not access external volumes from a host if the external volumes are spinning down. This prevents
the external volume status from changing to Blockade.
If external volume status changes to Blockade, the volume is automatically restored in several hours.
You can also manually restore the external volumes by reconnecting the external volume.
HUS and AMS 2000 series guidelines
•
Avoid unnecessary load to the external storage system. Path mode between storage systems
is Multi mode; therefore, when many external paths and mapping volumes are mapped, the
load to the external system is high; some commands from host to HP XP7 Storage or from HP
