Appendix D Installation in the SAN Boot Environment
D.3.1 Notes on design
Note the following about designing the environment:
Restrictions on slots for FC card connections
For the PRIMEQUEST 580A/540A/580/540
• In a SAN boot configuration, the OS can be installed via any slot in an IO
Unit. After OS installation, making multipath settings that include the slot
used for OS installation enables SAN boot from any slot of the IO Unit.
• In a SAN boot configuration, OS installation via a PCI_Box and SAN boot
cannot be performed.
For the PRIMEQUEST 480/440
• For PRIMEQUEST 480/440, connect the HBA card (FC card) used for SAN
boot in the PRIMEQUEST 480/440 to PCI slot #1 or #3.
• In a SAN boot configuration, OS installation via a PCI_Box and SAN boot
cannot be performed.
For the PRIMEQUEST 520A/520/420
In a SAN boot configuration, OS installation and SAN boot is possible from all
PCI slots in which an FC card has been mounted.
Select 1-to-1 WWPN for zoning.
When FC switches are used, zoning must be set up according to the system
configuration. If zoning is specified manually, either a specified port or WWPN
can be selected. However, for simplicity in the event of a failure, set 1-to-1
WWPN. If a specified port is used and a CA (host/FC switch port on an
ETERNUS unit) fails, zoning must be set up again.
Do not share the system disk.
The system disk cannot be shared by multiple servers. Be sure to use the host
affinity function for exclusive control of the system disk. Before using a non-
Fujitsu SAN storage unit, confirm that an equivalent function is available.
Restrictions on using the ETERNUS multipath driver
1
When the ETERNUS multipath driver is used, the individual logical units
(LUNs) in the ETERNUS unit must be equally assigned to all the HBAs
contained in one server.
2
If a zoning mode other than 1-to-1 WWPN is set, the possible configurations
do not allow access to multiple CAs in the same cabinet through an FC switch
from one HBA.
3
The number of paths is limited.
For Windows, the maximum number of paths that can be configured is 8.
For details, see the ETERNUS multipath driver manual.
