Dedicated Service LAN
Connections to both X and Y fabrics (for fault tolerance) for OSM system-up
maintenance (any one of these connections is valid as long as there are at least
two connections total):
°
Gigabit 4-port ServerNet adapters (G4SAs) installed in an IOAM enclosure
°
Ethernet 4-port ServerNet adapters (E4SAs), Fast Ethernet ServerNet
adapters (FESAs), or Gigabit Ethernet ServerNet adapters (GESA) installed in
a NonStop S-series I/O enclosure with IOMF 2 CRUs
You can configure the dedicated service LAN as described in the OSM Migration
Guide. HP recommends that you use a fault-tolerant LAN configuration.
A fault-tolerant configuration includes these connections to two maintenance switches:
A system console to each maintenance switch
Processor switch on the X fabric to the first maintenance switch
Processor switch on the Y fabric to the second maintenance switch
G4SA, E4SA, FESA, or GESA on the X fabric to the first maintenance switch
G4SA, E4SA, FESA, or GESA on the X fabric to the second maintenance switch
Only one connection between the maintenance switches is permitted. More than one
connection overloads network traffic, rendering the dedicated service LAN unusable.
