This section outlines the ETERNUS main unit settings. For details, see the manuals
supplied with the ETERNUS unit.
D.4.1 Reserving areas (RAID group, logical unit)
Reserve the areas required for setting up the SAN boot environment on the
ETERNUS unit. No special restrictions and notes apply to such areas used as the
system disk. For the procedure of reserving the necessary areas, see the ETERNUS
manuals.
D.4.2 Making settings for logical units
Allocate the reserved logical unit area to a CA.
Use ETERNUS setup software to allocate it. For details, see the ETERNUS manuals.
Two setting patterns are available:
z
If an environment in which HBA access is enabled is already set up (such as when
the ETERNUS unit is connected directly to the HBA), the HBA WWPN required
for this setting can be specified from the list displayed by ETERNUS setup
software.
Note: I/O processing across the ETERNUS unit must have been executed at
least once from the HBA.
z
In other cases, obtain information from the EFI console of the server containing the
HBA. For the procedure, see "Configuring the EFI driver."
Note the following about making settings for logical units:
•
Use the security function.
Use the host affinity function to limit the servers that can access each disk. For
example, if one ETERNUS unit is shared by two partitions, and if a system disk
and shared disk are provided for each partition, the servers (HBAs) that can
access each disk must be limited. This function must be used to prevent damage
to the system disks.
