1000Base-SX card settings

[David Watts]

I have a cluster of 2 L3000 both with 1000Base SX fibre cards. When I view the settings thru SAM for the primary it is shown as 10Mb half duplex with auto off but speed and duplex settings are greyed out, where as using lanadmin it's speed is shown as 1000,000,000 (1000Mb) but I'm not sure of the duplex. On the secondary server SAM shows it's card as 100Mb full with auto off and using lanadmin shows a speed of 100,000,000 (100Mb). The switch is speeds are 1000Mb full.

Which is right ? and how do I make sure that both cards are running at 1000Mb full duplex.

I am having slow backup speeds across the network to the secondary.

Many thank

As first step, I suggest to read the info found in files /etc/rc.config.d/hpgelan and its startup script /sbin/init.d/hpgelan

I have looked at these files and there are no settings in them.

David, I told that in order to customize your startup config.

You can use lanadmin to check the current config. If your 1000Base-SX card be lan3, you can type:

# lanadmin -x 3


In /sbin/init.d/hpgelan script you can read:

# /etc/rc.config.d/hpgelanconf defines the configuration parameters:
#
# HP_GELAN_INTERFACE_NAME Name of interface (lan0, lan1...)
# HP_GELAN_STATION_ADDRESS Station address of interface
# configured through lanadmin(1m)
# HP_GELAN_AUTONEG Enable or Disable the 1000-SX card's auto negotiation mode
# By default this mode is always enable
# Enable = 1
# Disable = 0
# HP_GELAN_FLOW_CONTROL Enable or Disable the card's flow control
# By default, it is always enable
# Enable = 1
# Disable = 0
# HP_GELAN_SEND_MAX_BUFS Change the number of send buffer descriptors
# to send at one time
# HP_GELAN_RECV_MAX_BUFS Change the number of receive buffer descriptors
# to send at one time
# HP_GELAN_SEND_COAL_TICKS Change the number of send coalesced ticks.
# HP_GELAN_RECV_COAL_TICKS Change the number of receive coalesced ticks.
# HP_GELAN_MTU Change the size of maximum transmission unit.
# HP_GELAN_SPEED Change speed/duplicity of 1000-T cards
# 1 = 10hd
# 2 = 10fd
# 3 = 100hd
# 4 = 100fd
# 5 = auto_on

This is the info needed to configure your 1000Mb-SX lan card.

any idea why SAM is showing different to lanadmin ?

1000BaseT is "relatively" recent, when was the last time you applied a SAM patch?
