Configuring the SAN Boot Environment

1.3.4 Notes on system operation

Keep the following points in mind when operating the system.

Be sure to confirm that the SAN storage and FC switch are completely in the Ready state.

Use the MMB Web-UI to set the time period until the power-on of the partition.

When the partition is started, the boot disk may not be found. In this case, try partition reset from the UEFI.

Record the dates and times of server switching (FC card replacement. Including move.) on separate media. Prepare
this media in case the possibly faulty part of the hardware can no longer be located in an event log primary analysis, at
a hardware failure, or at the occurrence of another problem.

When the FC card has been replaced with a maintenance part, the HBA UEFI/Legacy BIOS must be reset. Also, the
SAN storage unit must be reset.

In the SAN boot environment, OS boot may fail depending on the quality of the FC transmission path. In such a case,
use the FC switch and SAN storage unit to check the alarm or system status and identify the faulty part. Then, select
[Reset] from the [Power Control] window of the MMB Web-UI to restart the system.

In a Linux environment, a SAN boot in a multipath configuration may be performed. To start up in Rescue mode and
automatically mount the ETERNUS disk in such cases, enable only one FC port in advance of startup.
If the multipath configuration is left as is, the system may fail to start up normally. Even if you do not use automatic
mounting, we recommend enabling only one FC port in advance of startup in Rescue mode in order to prevent
operational errors.
