6-28 Server Priority Manager Operation
Hitachi Universal Storage Platform V/VM Hitachi Performance Manager User’s Guide
Grouping Host Bus Adapters Server Priority Manager allows you to create an SPM group to contain multiple
host bus adapters. All the host bus adapters (HBAs) in one SPM group must be
of the same priority. Prioritized WWNs (i.e. high-priority HBAs) and
non-prioritized WWNs (i.e. low-priority HBAs) cannot be mixed in the same
group.
You can use an SPM group to switch priority of multiple HBAs from prioritized
to non-prioritized, or vice versa. You can also use an SPM group to set the
same upper limit value to all the HBAs in the group.
Containing Multiple HBAs in an SPM Group
A host bus adapter can be contained in only one SPM group. To create an SPM
group and contain multiple host bus adapters in the group, take the following
steps:
To contain multiple HBAs in an SPM group:
1. Start Server Priority Manager.
The Server Priority Manager window is displayed.
2. Select the WWN tab.
3. In the lower-left tree, select and right-click the Subsystem folder.
4. From the pop-up menu, select Add New SPM Group.
5. In the Add New SPM Group window, enter the name of the SPM group
and then select OK.
An SPM group is created. An SPM group icon ( ) is added to the lower-left
tree.
6. Select an HBA from the upper-left tree and select an SPM group from
the lower-left tree. Next, click Add WWN.
Repeat this operation until all the desired HBAs are added to the SPM
group.
Notes:
Select a host bus adapter from below Monitor. You cannot add HBAs from
below Non-Monitor to SPM groups.
When you select a host bus adapter which is already contained in some
SPM group from the upper-left tree, the Add WWN button is not
activated. Select a host bus adapter which is not contained in any SPM
groups.
Windows users can add a host bus adapter to an SPM group by dragging
the host bus adapter to the SPM group.
7. Click Apply.
