Switch to manual configuration

To disable automatic procedures to take back your changes you have to enable the manual configuration mode. 

# netadm enable -p ncp DefaultFixed

Nodename

# svccfg -s svc:/system/identity:node setprop config/nodename = astring: camponotus
# svcadm refresh svc:/system/identity:node
# svcadm restart svc:/system/identity:node

Interfaces

Initial setup

# ipadm create-ip net1 
# ipadm create-addr -T static -a local=192.168.5.101/24 net1/v4mailcluster1

IPMP

# ipadm create-ip net2
# ipadm create-ip net3
# ipadm create-addr -T static -a 192.168.5.102/24 net2/v4ipmptestadress
# ipadm create-addr -T static -a 192.168.5.103/24 net3/v4ipmptestadress
# ipadm create-ipmp ipmp0
# ipadm add-ipmp -i net2 -i net3 ipmp0
# ipadm create-addr -T static -a 192.168.5.101/24 ipmp0/v4mailcluster0

# ipmpstat -i
INTERFACE   ACTIVE  GROUP       FLAGS     LINK      PROBE     STATE
net2        yes     ipmp0       -------   up        ok        ok
net3        yes     ipmp0       --mbM--   up        ok        ok

# ipmpstat -an
ADDRESS                   STATE  GROUP       INBOUND     OUTBOUND
::                        down   ipmp0       --          --
192.168.5.101              up     ipmp0       net3        net2 net3

Set one interface to standby: 

# ipadm set-ifprop -p standby=on -m ip net2
# ipmpstat -i
INTERFACE   ACTIVE  GROUP       FLAGS     LINK      PROBE     STATE
net3        yes     ipmp0       --mbM--   up        ok        ok
net2        no      ipmp0       is-----   up        ok        ok
# ipmpstat -g
GROUP       GROUPNAME   STATE     FDT       INTERFACES
ipmp0       ipmp0       ok        10.00s    net3 (net2)

More sophisticated with aggregations and vnics

<source lang=bash>

  3. dladm show-link

  1. zonecfg -z zone01

Change address

1. Create new interface: 

# ipadm create-addr -T static -a 192.168.5.111/24 ipmp0/v4mailcluster1

2. Login to new IP.

3. Delete the old interface: 

# ipadm delete-addr ipmp0/v4mailcluster0

DNS

Client

# svccfg -s svc:/network/dns/client setprop config/nameserver = net_address: "( 0.0.0.0 192.168.1.1 )"
# svccfg -s svc:/network/dns/client setprop config/search = astring: "timmann.de blindhuhn.de"
# svcadm refresh svc:/network/dns/client:default
# svcadm restart svc:/network/dns/client:default

Activate dns in nameservice switch (nsswitch.conf): 

# perl -pi -e "s/^hosts:\s+files$/hosts: files dns/g" /etc/nsswitch.conf
# nscfg import -f svc:/system/name-service/switch:default
# svcadm refresh name-service/switch
# svcprop -p config/host svc:/system/name-service/switch:default
files\ dns

Server

# groupadd -g 53 dns
# useradd -u 53 -g dns -d /var/named -m dns
# usermod -A solaris.smf.manage.bind dns
# svccfg -s svc:network/dns/server:default setprop start/group = dns
# svccfg -s svc:network/dns/server:default setprop start/user  = dns
# svccfg -s svc:network/dns/server:default setprop options/ip_interfaces = IPv4
# svccfg -s svc:network/dns/server:default setprop options/configuration_file = /etc/named.conf
# svcadm refresh svc:network/dns/server:default
# svcadm enable  svc:network/dns/server:default

Set tcp/udp parameter (formerly ndd)

<source lang=bash>

  1. ipadm show-prop -p smallest_anon_port tcp

PROTO PROPERTY PERM CURRENT PERSISTENT DEFAULT POSSIBLE tcp smallest_anon_port rw 1024 -- 1024 1024-65535 </syntaxhighlight>

<source lang=bash>

  1. ipadm set-prop -p smallest_anon_port=9000 tcp
  2. ipadm set-prop -p smallest_anon_port=9000 udp
  3. ipadm set-prop -p largest_anon_port=65500 tcp
  4. ipadm set-prop -p largest_anon_port=65500 udp

</syntaxhighlight>

Jumbo Frames

The MTU of an ipadm-interface can never be greater than its underlying dladm-interface. To change the dladm-interface the ipadm-interface has to be disabled (DOWNTIME!? BE CAREFUL!). <source lang=bash>

  1. ipadm disable-if -t iscsi0
  2. dladm set-linkprop -p mtu=9000 iscsi0
  3. ipadm enable-if -t iscsi0
  4. ipadm set-ifprop -m ipv4 -p mtu=9000 iscsi0

</syntaxhighlight>

Aggregate for iSCSI

This is cruel but worked on our ciscos: <source lang=bash>

  1. dladm create-aggr -m trunk -P L4 -L off "-l iscsi"{0..7} iscsi_aggr0 | /bin/sh
  2. dladm show-aggr -P iscsi_aggr0

LINK MODE POLICY ADDRPOLICY LACPACTIVITY LACPTIMER iscsi_aggr0 trunk L4 auto off short

  1. dladm show-aggr -L iscsi_aggr0

LINK PORT AGGREGATABLE SYNC COLL DIST DEFAULTED EXPIRED iscsi_aggr0 iscsi0 no no no no yes no -- iscsi1 no no no no yes no -- iscsi2 no no no no yes no -- iscsi3 no no no no yes no -- iscsi4 no no no no yes no -- iscsi5 no no no no yes no -- iscsi6 no no no no yes no -- iscsi7 no no no no yes no </syntaxhighlight>

Set TCP parameters in immutable zones

In normal immutable mode zlogin -U does not change it: <source lang=bash> root@global# zlogin -U immutable-zone ipadm set-prop -p _time_wait_interval=30000 tcp ipadm: set-prop: _time_wait_interval: Invalid argument provided

root@global# zlogin immutable-zone ipadm show-prop -p _time_wait_interval tcp PROTO PROPERTY PERM CURRENT PERSISTENT DEFAULT POSSIBLE tcp _time_wait_interval rw 30000 -- 60000 1000-600000 </syntaxhighlight>

Need to boot into writable: <source lang=bash> root@global# zoneadm -z immutable-zone reboot -w

root@global# zlogin -U immutable-zone ipadm set-prop -p _time_wait_interval=30000 tcp

root@global# zlogin immutable-zone ipadm show-prop -p _time_wait_interval tcp PROTO PROPERTY PERM CURRENT PERSISTENT DEFAULT POSSIBLE tcp _time_wait_interval rw 30000 30000 60000 1000-600000

root@global# zoneadm -z immutable-zone reboot </syntaxhighlight>
