Assigning a processor blade
Assigning a processor blade to a resource
You can assign a processor blade to resources (logical devices, external volumes, and journal
volumes).
1. In the Remote Web Console main window, in the Storage Systems tree, select Components.
2. In Components, select the name of the DKC for which you want to assign a processor blade.
Processor blades can be viewed in the Processor Blades tab.
3. Select a processor blade for which you want to change the settings, and then click Edit MP
Blades.
4. In the Edit MP Blades window, disable or enable Auto Assignment.
• Select Enable if the processor blade can be automatically assigned. This is the default.
• Select Disable if the processor blade cannot be automatically assigned.
5. Click Finish.
6. In the Confirm window, confirm the settings, in Task Name type a unique name for this task
or accept the default, and then click Apply.
If Go to tasks window for status is checked, the Tasks window opens.
Changing the processor blade assigned to an LDEV
1. In the Remote Web Console main window, in the Storage Systems tree, select Logical Devices.
LDEVs are shown in the LDEVs tab.
2. Select the LDEV for which you want to change the processor blade.
3. Click More Actions, and then select Assign MP Blade.
4. In the Assign Processor Blade window, specify the processor blade in Processor Blade.
5. Click Finish.
6. In the Confirm window, confirm the settings, in Task Name type a unique name for this task
or accept the default, and then click Apply.
If Go to tasks window for status is checked, the Tasks window opens.
CAUTION:
• If you change the processor blade ID for an LDEV, do this only when the I/O load is as low
as possible. Do not change the processor blade ID when the I/O load is high (for example:
during initial copy of Business Copy, Continuous Access Synchronous, or Continuous Access
Journal).
• After you change the processor ID for an LDEV, wait more than 30 minutes before you try to
change it again for the same LDEV.
• When you change the processor blade ID for an LDEV, you should use Performance Monitor
before and after the change to check the load status of devices.
Using a system disk
A system disk is a special LDEV used in the storage system for specific purposes. A system disk is
not required in a storage system, but is recommended for buffering of the audit log. A system disk
should not be used for storing user data. After a system disk is created, the system knows what
types of information the system disk is used for and all appropriate information is automatically
sent to the system disk.
For example, when the system disk is used as an audit log buffer, you set parameters to enable
the audit log buffer. The Audit Log feature recognizes the LDEV number of the system disk and then
