Restriction when TPM (Trusted Platform Module) is installed

LPAR manager does not support TPM (Trusted Platform Module). Set the TMP
setting in the EFI setup menu as follows:
Select System Settings > System Security > TPM Settings. And then disable
TPM Device.
For details, see the Hitachi Compute Blade 500 series EFI User's Guide.

Isolation/degradation for CPU, memory, or PCI device

• System event log (SEL) collection for a system unit or alert notice for SC/
BSM is performed when isolation/degradation occurs in a CPU, a memory,
or a PCI device.
• Some devices cannot be recognized at the next LPAR manager startup
time, and some LP configuration information are deleted or reconfigured
when isolation/degradation occurs in a CPU, a memory, or a PCI device.
Note that, by using the KeepConfig option, the LPAR manager holds the
LPAR manager configuration in the management module. For details, see
Backing up the LPAR manager configuration as of a time before device
isolation on page
• Restore backup files to return to the original LP configuration information
before starting a LPAR manager when isolation/degradation is recovered
due to hardware exchange. If the backup file is not created, check that
the LP configuration is changed or not, and set the LP configuration as
needed.
• When you migrate an LPAR with one or more FC ports isolated on the
source server blade to the destination server blade with FC ports with no
errors in Concurrent Maintenance mode, the FC ports may be isolated
even on the destination server blade.
For removing an FC port isolated, see the Hitachi Compute Blade LPAR
Migration Guide.

CPU core degradation

When restarting LPAR manager in a state that CPU core degradation occurs,
LPAR manager cannot recognize a core which was degenerated, and the
following events occur.
• A mapping of physical processor for logical processor in all LPARs is
initialized.
• A processor group number of core which was degenerated is initialized.

Restrictions on use of Onboard LAN

Note the following restrictions when you use Onboard LAN on CB 520X B1/
B2/B3 server blades.
• Disable a port on an OS when you do not desire to allow the OS to use
the port.
