1.3.3 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 or FCoE 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 and converged network adapter
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 or the converged network adapter has been replaced with a maintenance part, the HBA
UEFI/expansion 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 or FCoE transmission
path. In such a case, use the FC switch or FCoE 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.
For details, see the notes on operating system installation in 1.3.2 Notes on system installation.
