Secure and non secure item page

In our environment,
few pages were giving error "

"This page contains both secure and nonsecure items. Do you want to display the nonsecure items?"

after removing this tag <html:base /> the error went away.

configuring devices

AIX

Like panacea, just one command cfgmgr.




Solaris:
Either of the following commands

1 and 2 for newbies :)

1. In Open Boot PROM, use: boot -r
2. With your OS online, reboot your system with this flag:
   reboot -- -r
   (The system boots with the -r flag as it does with boot -r.)
3. Execute these commands: drvconfig, devlinks, disks

view devices and status

 cfgadm -la
prtdiag

network management

I'll try to explain how to create link aggregation a.ka. Ether channe(AIX), Net-bond(Linux).

Before we create one, we have to know, how many interfaces are present in that system.

List network interfaces.

AIX

# lsparent -C -k ent
ent0 Available 03-08 10/100/1000 Base-TX PCI-X Adapter (14106902)
ent1 Available 03-09 10/100/1000 Base-TX PCI-X Adapter (14106902)



Linux

systool -c net
Class = "net"

Class Device = "bond0"
Device = "0000:02:01.0"

Class Device = "eth1"
Device = "0000:02:05.0"

Class Device = "lo"

Class Device = "sit0"


ip link show
1: lo: mtu 16436 qdisc noqueue


link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: mtu 1500 qdisc pfifo_fast qlen 1000
link/ether 00:0c:29:81:c0:13 brd ff:ff:ff:ff:ff:ff
3: sit0: mtu 1480 qdisc noop
link/sit 0.0.0.0 brd 0.0.0.0

Solaris

# dladm show-dev
e1000g0 link: up speed: 1000 Mbps duplex: full
e1000g1 link: up speed: 1000 Mbps duplex: full

change NIC settings to full duplex/Autoneg

AIX
chdev -l 'ent0' -a media_speed='1000_Full_Duplex'

Linux
ethtool -s speed 1000 duplex full autoneg on
ethtool --change eth0 autoneg off speed 1000 duplex full

ethtool eth0 (same as entstat ent0 on AIX)

Etherchannel configuration




AIX

smitty etherchannel

very easy huh :)

Linux
# ls "$PWD/ifcfg-eth0"
/etc/sysconfig/network-scripts/ifcfg-eth0
# cat ifcfg-eth0

MASTER=bond0
DEVICE=eth0
SLAVE=yes
ONBOOT=yes
USERCTL=no
BOOTPROTO=none

#cat ifcfg-eth1

MASTER=bond0
DEVICE=eth1
SLAVE=yes
ONBOOT=yes
USERCTL=no
BOOTPROTO=none

add/append following lines to /etc/modprode.conf
alias bond0 bonding
options bond0 mode=balance-alb miimon=100

modprobe bonding (for loading bond module)

service network restart
less /proc/net/bonding/bond0
Output
Ethernet Channel Bonding Driver: v3.2.4 (January 28, 2008)

Bonding Mode: load balancing (round-robin)

Solaris




the last step changes the hostname on to aggr1 .
A reboot is required .

For setting jumboframes
edit MaxFrameSize /kernel/drv/e1000g.conf/hme.conf
edit AutoNegAdvertised for setting full duplex etc


# dladm show-aggr -s
