Implementing a disk array
You must not change the disk array during system operations. Otherwise, the
system would lose all data.
If you select [New Configuration], the hard disk will lose all data.
Power operation
Follow the prescribed procedure for power operation. Power input or output not
according to the prescribed procedure may cause problems to the system
equipment.
Faulty disk
If you attempt to replace a faulty disk using an incorrect procedure, data on the
disk may be corrupted. Before starting disk replacement work, back up the
data.
Replacing a hard disk without failure will corrupt the data on it. Do not remove any
hard disk other than the faulty disk.
Connecting a cable to the management module
When you connect the management module over a network, the system will incur
an error if a device assigned with the same IP address as for the BMC on the
management module or server blade exists on the network.
After the end of a network configuration, connect a cable to the management
module.
N + M cold standby function
When the N+M cold standby function is enabled, Pre-configuration is
automatically executed and the status LED (CND) on the server blade lights
solid green after the POWER LED on the front panel lights solid orange.
Confirm that the POWER LED of the front panel lights solid orange to show
Pre-configuration is completed before executing step 3 described above.
Make sure to use the same LPAR manager firmware version as the active
partition for the standby partition. Otherwise, N+M failover may fail.
Do not move the EFI Shell to the highest booting priority in the EFI Setup menu. If
the EFI Shell is on the top of the boot option, the OS will not successfully boot
after N+M switching and failback.
For a Xeon server blade, executing the Pre-configure automatically changes the
SAN booting priority to the lowest of the priority settings.
If you change the LPAR configuration (processors, memory, or device
assignment), make sure to implement [F9]: "Save Configuration" on the LPAR
manager Menu screen. For details, refer to "Saving Settings on the LPAR
manager Screen".
When a switching alert is issued by the BSM command execution, the active
partition is forcibly powered off.
