“No Mapping/Masking” Mode
All servers that can target the MAGNITUDE device can also see all of the
LUNs on the device. HP Clustered File System can be installed normally
with this configuration. However, you will need to set up the LUNs that
will be used with HP Clustered File System before you begin the HP
Clustered File System installation. See section “9. Create LUNs for the
Membership Partitions and Modify Partition Tables” on page 12 for
information about the LUNs required for HP Clustered File System
operations.
“New Server See Nothing” Mode
Only those servers that have been identified by the MAGNITUDE storage
array are allowed to see specifically mapped LUNs. The storage array
uses the WWID of the FC Host Bus Adapter to manage this mode of
operation.
Before installing HP Clustered File System, you will need to perform the
following procedure, which ensures that the LUNs are available when
you configure HP Clustered File System.
Complete the following steps:
1. Set up the LUNs that are going to be used by HP Clustered File
System. (See section “9. Create LUNs for the Membership Partitions
and Modify Partition Tables” on page 12 for information about the
LUNs required for HP Clustered File System operations.)
2. When booting each server, press Ctrl-Q to enter the QLogic Setup
Program.
3. Select “Scan for Fibre Devices” from the menu.
4. Page through the results until you see the
MAGNITUDE device.
5. On the
MAGNITUDE device, map the LUNs to the WWIDs.
Exit the QLogic Setup Program. The server will reboot automatically.
